Common Questions About Security and Alarm Cables, Answered

Not sure which type of security or alarm cable your facility or system needs? Hopefully, these answers to common questions can help!

What cable is used for alarm systems? Security and alarm systems are usually wired with small-gauge wire specifically designed for the purpose.

For instance, many security systems are wired with 12 and 18 AWG gauge alarm wire, as these low-voltage applications do not necessarily require larger, heavier wires.

However, larger or wire gauges may be required depending on the circumstances.

Also, there are some unique requirements for some systems. For instance, fire alarm cables must be made with specific insulation that is heat resistant and which does not produce toxic smoke when burned.

What gauge cable do you need for alarm systems? Only your specific system requirements can answer that question, but often large wire gauges (that is, smaller wires) are used as security and alarm cables because of the low-voltage, low-current application.

What is the best cable for alarm systems? Copper is the most commonly used conductor for security and alarm systems because it offers excellent conductivity and flexibility.

Can you use Cat6 cable for alarm systems? Some access control systems can actually use Cat5E ethernet cables for power; if they can accept them, then Cat6 cables, which are backward-compatible with Cat6 cables, can be used.

This does not mean that all security and alarm systems can be wired with Cat5E or Cat6 cables. If you are not sure, consult an electrician.

What’s the difference between Type 1 and Type 2 alarm cables? The difference here is primarily related to insulation. Both Type 1 and Type 2 alarm cables must have a resistivity of less than 100 Ω/km, but Type 1 cables must have low smoke, zero halogen insulation and sheathing whereas Type 2 cables are made with PVC insulation and sheathing.

Does my alarm cable need to be shieded? That depends primarily on the unique circumstances of the application. EMI, or electromagnetic interference, can badly scramble if not incapacitate an alarm system. If there is a high volume of EMI in your location that affects your security system, then it is probably worth it to get shielded security and alarm cables.

What’s the difference between riser-rated and plenum-rated fire alarm cable? The difference between riser-rated and plenum-rated fire alarm cable has to do with their insulation.

Plenum-rated fire alarm cable offer a higher fire resistance rating than riser-rated cable.

Riser-rated cables are meant to be used in the space above a drop ceiling and are made with a special, non-toxic insulation that helps control the propagation of dangerous fumes in the event of a fire.

Plenum-rated cables are more protective and expensive than riser-rated cables and can be used in riser space, but riser-rated cables cannot be used in plenum space.

Marine Battery & Cable Maintenance

Your boat’s battery is necessary to start the engine, power the electrical system, including lights and navigation, and much more.

For boats powered by a trolling motor, it i the only power source for the vessel.

Without it, you would be dead in the water.

With that said, here are some high-level ways to take care of your marine battery and cables.

Protect and Clean the Terminals The easiest aspect of marine battery maintenance is to keep the terminals clean. Over time, discharge will exude from the terminals, and this corrosion can damage the battery and make it difficult to establish a solid electrical connection.

Use a solution of warm water and baking soda with a battery terminal brush or a steel wire brush to scrub them clean from time to time.

Then, apply some dielectric grease to the terminals. A thin coating will help prevent water ingress and almost entirely prevent corrosion.

Keep the Battery Charged A fully charged battery will last longer than one that is fully discharged and allowed to remain at a low level. If possible, you should never allow your battery to die.

Keep your battery fully charged before leaving port. When in port, you may want to hook it up to a battery maintainer with a trickle charge function.

Protect It Against Extreme Temperatures For small vessels that are removed from the water during the winter, it might be a good idea to remove your battery when your vessel is dry-docked.

Keep it somewhere that preferably won’t experience freezing temperatures, as these can damage batteries, and keep it charged throughout the winter.

Use Only Approved Marine Battery Cable For wiring purposes and battery leads, it is important to use only USCG and UL-approved marine battery cables.

Marine battery cable is made with very thin copper conductors that are individually tinned. This does two things: it makes them very flexible, and it helps prevent corrosion as the tinned copper is better insulated.

Use the Right Size Marine Battery Cable It is also critical to use the right gauge of marine-grade wire for the application.

The use of a wire in a gauge that is inappropriate for the load of the circuit will cause the wire to overheat, can cause the insulation to break down, and can cause fires.

Protect Against Chafing Be cognizant of where the cable exits and enters from any compartments in your vessel. These are all chafing points.

If the wire’s insulation chafes and wears through, you’re at a much higher risk of fire.

Instead, protect your cables with conduit, electrical tape, silicone, or some other buffer at entry points. Consult a marine electrical engineer if you have questions.

Welding Cable for Sale: Three Key Features to Assess

When you’ve got welding cable on its last legs and are looking for a replacement, one of the best things you can do is buy an exact match for the cable you’ve been using (assuming you were using a suitable cable in the first place).

That isn’t always possible, so if you’re looking for welding cable for sale, judge quality by these three criteria.

Voltage Rating This is the most important single consideration you need to make when looking at prospective welding cables.

Voltage rating is an indication of how much voltage the cable can work with, which will impact how much current it can carry as well.

Thicker cables can carry a higher voltage than thinner cables, all things considered.

Many welding cables are rated to 600V, just like much building wire. Whatever the case, be entirely certain that the application for which the cables are intended is within the cable’s voltage range.

Insulation The insulation with which welding cables are made also plays a prime role in how well they can fill their role.

Welding cable should be made with insulation that is extremely durable and resistant to abrasion. This is because these cable will often be used outdoors in extreme conditions and temperatures.

Many types of welding cable for sale are made with insulation that is resistant to weather, moisture, high and low temperatures, acids, oils, bases, and oil and gasoline.

Some of these types of cable are even made with insulation that is resistant to ultraviolet light as well.

Because of these reasons, welding cable for sale is also often marketed as solar PV wire, inverter cable, and as leads for motors and generators.

It’s also customary for these types of cable to be made with red and black insulation, making it suitable for use as battery wire.

Insulator Strand Count (Flexibility) Last but not least, it is important to choose a flexible welding cable that has a high conductor strand count.

Welding cable for sale is customarily manufactured with a very high conductor strand count (using fine, 100% copper conductors) as these are more flexible than larger, stiffer wires.

Flexibility is often used as a prerequisite determinant of quality in welding cable for sale, as these large, heavy cables must often be used outside or in tight spaces, in which it would be difficult to manipulate stiffer cables.

Therefore, just like marine battery cables, cables used for welding applications should have a high strand count and be extra flexible.

Where Can You Find High-Quality Welding Cable for Sale? If you’re looking for quality welding cable for sale, we’ll give you the place to start looking: EWCS Wire, at EWCSWire.com.

They carry a wide range of electrical wires and cables (including specialty wire) including extra-flexible welding cable made with ultra-durable, abrasion and oil-resistant EPDM insulation.

Two Important Things You Need to Know About Marine Electrical Wire

Do you own a boat? Are you a member of a ship’s crew? Are you a ship’s mechanic or an electrician by trade?

If you answer yes to any of these questions, you will at some point or other come across marine electrical wire in the course of your career.

Something important you’ll need to keep in mind is that marine electrical cable and wire is not the same as standard building wire; nor is it the same as automotive battery wire.

Here are the two big defining traits.

Marine Electrical Wire Is Highly Flexible If there’s one thing you need to know about marine electrical wire (also sometimes called marine battery cable or marine battery wire) it’s that it’s highly flexible.

This is accomplished by making these conductors out of very high strand counts of very thin conductors.

Typically, marine battery wire conductors are made from pure, 100% copper and each conductor is very thin. Doing so makes the cable very flexible.

Why is this necessary? Well, for that, there are three things you need to know about seagoing vessels.

One is that they are constantly in motion as a result of the water. Another is that being in motion puts potentially high stress on everything within.

Finally, the interior of a vessel is often very cramped. Getting thick, heavy, stiff electrical conductors in and out of a vessel’s interior for the purpose of establishing an electrical connection would be very difficult without flexible wire.

Marine Electrical Wire Is Tinned Equally important to flexibility is the fact that marine electrical wire is protected against corrosion.

This is accomplished by treating the conductors with tin, or “tinning” them. In the case of marine electrical wire, usually, the conductors are individually tinned, eliminating any proverbial chinks in the armor.

Saltwater is noxiously corrosive and copper is highly suspect to chemical attack. Fortunately, tin is much more resilient, so protecting this type of battery cable against these influences is a must.

Saltwater, however, is not the only dangerous substance with which marine cables frequently come in contact. There are also gasoline and oil, acids and alkaline chemicals, and more.

As a result, most high-quality marine electrical cable is resistant to moisture, oil, gasoline, acids and alkalis, and even abrasion.

This helps protect marine electrical cables not only against seawater-induced corrosion but against other forms of chemical assault.

Where Can You Find High-Quality Marine Electrical Wire? Ensuring marine electrical battery cable and wire meet these two important criteria is tantamount to producing reliable, reputable, quality electrical equipment.

These are some of the reasons it is inadvisable to use automotive battery wire on vessels. While it might be flexible enough to establish connections, it is rarely if never adequately protected against corrosion.

If you’re looking for quality marine electrical wire that satisfies these requirements, visit EWCS Wire online at EWCSWire.com.

They carry a wide range of marine electrical cable and other specialty electrical conductors including welding cable, battery and alarm cable, armored cable, tray cable, aluminum cable, and of course building cable.

Wire Voltage Ratings, Explained

Voltage rating is one of the most basic, fundamental ratings associated with electrical wire and cable, given in volts.

Voltage itself is a measurement of electrical potential, calculated by multiplying a given electrical current (in amperes, I), by the resistance of a conductor, (in ohms, Ω).

The material of the conductor, as well as the thickness, will all impact resistance. These things, being variables from which voltage is drawn, affect voltage rating.

Think of voltage as the force “pushing” the electricity through a wire or cable, similar to how plumbing pipes experience line pressure, except that line pressure is measured in PSI instead of volts.

Just like with water pipes, it is essential never to exceed the voltage rating of a given conductor - but instead of a burst pipe, exceeding the voltage rating of an electrical conductor can cause overheating, fires, and an elevated risk of dangerous electrical shock.

But what exactly is a wire’s voltage rating?

So, What Really Is 600 Volt Wire? The voltage rating is the highest voltage that can be continuously applied to an electrical conductor in a sustained manner without the risk of overheating or circuit failure.

Voltage rating is calculated by accounting for Ohm’s Law, related to electrical resistance, and the Power Calculation Formula, which is related to power output.

Voltage rating is affected by the diameter of the wire, the electrical resistance of the material from which it is made, and the dielectric rating of the conductor’s insulation. All things being equal, the thicker the wire, the greater voltage it can tolerate. However, material and insulation can affect this, too.

It is critical never to exceed the posted voltage rating of an electrical conductor because it will cause the wire to overheat and increases the risk of electric shock.

Excess voltage can also be extremely destructive to sensitive electronic components and connections. Sustained, excessive voltage can cause them to melt or burn out.

What Is Voltage Drop? Voltage drop is the natural loss of electrical potential of an electrical stream running through an electrical conductor, which is the product of the conductor’s length, thickness, and resistance.

Voltage drop is an undesirable condition that impacts the voltage supplied at one point of a given circuit. Electric Codes (such as the NEC) may be responsible for setting guidelines for the maximum voltage drop permitted in a circuit in order to ensure an efficient supply of power.

Where Can You Get High Quality 600 Volt Wire and Specialty Wire? Looking for high-quality 600-volt wire, building wire, and other specialty electrical wire and cable? Visit EWCS Wire online at EWCSWire.com.

Obtaining the Most Agile Welding Cable for Sale

Agility is important for a few kinds of electrical wires, but it isn't required for all of them for the same rationale. With this in mind, marine battery cable is often designed to be very pliable to fit through a boat's tight spaces more readily.

Welding cables for sale are another kind of cable that need a high level of flexibility during production. To be able to withstand the rigors of the industry, they must be designed to be as flexible as possible, much like marine battery wire.

There's another reason why welding cables for sale need to have a high degree of flexibility: a large percentage of activities involving welding are in industrial or construction environments. As you would expect, these workplaces are not "flexible." The welding cable, however, has to be.

It is essential that the power cables that feed welding equipment be able to withstand the dangers of the working site while also being flexible enough to meet the needs of the welders. With no flexibility in either the welding equipment or the project as a whole, this leaves just one option: the welding cable.

Because of this, welding cable must have the greatest degree of flexibility. Welding cables on the market are marketed as "very flexible," however there is no objective standard to measure their flexibility, and this is a concern for some.

To determine the most flexible welding cable, just count the number of strands in the cable before making your selection. One of the most reliable methods for determining a welding cable's degree of pliability. For a given diameter, the stiffer a cable will be if the number of conductor strands is also increased.

If you're looking for an easy method to measure your flexibility, this is a great option. In contrast to AWG, strand count as a single vector. The more strands in a welding cable, the more flexible it should be.

Welding wire for sale isn't only beneficial because it's flexible. In addition, the insulation of welding cables must be resistant to a broad variety of severe environmental conditions.

Insulation resistant to environmental conditions, such as temperature fluctuations, humidity, storms, and even UV radiation, is very important for a welding cable. Welding cables that are naturally resistant to chemicals, as well as gasoline and oil, are especially beneficial because of the nature of work sites.

Even better if you can discover a welding wire with highly robust insulation that is also mechanically strong. The harder the insulation, the better it can endure abrasion, regardless of chemical resistance. The fact that certain welding cables are useful as battery and solar array leads is a result of their wide range of properties.

Is Marine Battery Wire Silver?

If you’ve ever done any wiring on a boat, whether you’re in the electrical trade or just a casual boater, this is a legitimate question. After all, stripping marine battery wire will expose some silvery filaments that do, after all, look silver.

So are they? Let’s look at what qualifies marine battery wire and the reasons it is designed and manufactured according to those qualifications.

So What Is It Made of? First things first, marine battery cable is actually not silver, although it looks like it.

Ironically, silver is an excellent electrical conductor, among the best known. However, silver, like copper (which is used for most electrical conductors, including marine cable as you are about to see) suffers from a common deficiency.

Both are prone to oxidation - that is, both silver and copper corrode. As you might know, these effects are broadly exacerbated in humid and saltwater environments - both of which ships and boats are prone to encounter.

To answer the question initially posited by this article, marine battery wire actually is made of copper conductors - it just has a special protective coating that helps to insulate it from the ravages of saltwater-induced oxidation.

Marine battery cables and wires are made from many fine strands of copper conductors that are then individually coated, typically in tin. These tin-coated strands can much better resist environmental influences that would cause corrosion and degradation.

This tin coating is readily apparent whenever you strip the wire - such as to make connections to the terminals of a battery. They do also give marine wire the appearance of being made of silver - but make no mistake about it, they are not.

What Should Marine Battery Wire Be Able to Withstand? While the threat of corrosion is one of the most noxious influences faced in most marine environments, it is not the only factor against which marine-grade cables should be able to stand.

Consequentially, many tinned copper marine grade wires are also made with special insulation that makes them uniquely able to withstand acid, abrasion, gasoline, oil, and of course, moisture.

In addition, marine battery cables are made with a high number of strands which keep them extra flexible. This is a bonus given the tight confines of the inner workings of most vessels, as cables with superior flexibility are easier to manipulate into location and can better navigate the tight recesses within boats. Additionally, highly flexible cables withstand fatigue better.

Where Can You Get Marine Grade Copper Battery Cables? Looking for high-quality marine-grade battery wire and cable? Visit EWCS Wire online at EWCSWire.com.

They carry a wide range of marine battery wire that is United States Coast Guard, American Boat and Yacht Council, and UL-approved.

3 Factors To Take Into Account When Choosing Battery Cables

When talking about battery management systems of any kind, battery cables are among the most important components. It does not matter if we´re talking about automotive or marine battery cables, they must ensure you always have stable power and prevent battery drain.

This not only means that they have to be properly secured and protected. Size and gauge play a vital role when choosing the right battery cable for your system.

Here are three things you must always bear in mind when selecting and installing your battery cables.

Proper Gauge Understanding cable gauges can be a problem for many as gauge measurements can be very counterintuitive. During the early days of the cable industry, cables were made out from a strand of iron that needed to be thinned out by passing them through increasingly narrower drawing dice until they were the right diameter. A 0 gauge cable meant that it didn't need to be reduced or gauged, while a 30 gauge cable went through 30 drawing dice until it was thin enough for its intended use.

Using the wrong gauge in your battery system is one of the most common causes of power problems. Using gauges that are too thick will not be able to properly distribute power as diameter affects resistance. If your battery cable is too thin for your requirements there is an increased risk of short circuit and even fire.

The best way to prevent gauge problems is to make amp and gauge charts available for everyone involved in the installation and maintenance process.

Proper Length In the same way cable diameter affects resistance, so does battery cable length. Voltage progressively drops while traveling through a cable. So, the longer the distance, the lower the voltage. If the cable is too long, the electrical resistance will cause the voltage to drop below usable levels.

When trying to determine the correct length and gauge of your battery cable, take Ohm´s Law into account: Voltage drop (V) equals current in amperes (I) times the resistance expressed in Ohm (R), or V=IR.

Consider that thinner wires always have a higher voltage drop rate than shorter but thicker wires. Make sure you and everyone involved take the time to calculate and select the correct battery cable gauge and length.

Strand Count First, we must understand the difference between cables and wires. A wire is a single conductor, usually made of copper, which can be bare and twisted or be a single thick strand that is difficult to bend. A cable is a group of wires bundled together and insulated.

The strand count inside your battery cable will affect its flexibility: the higher the strand count, the higher its flexibility. Marine battery cables, for example, need to be flexible enough to be driven through narrow spaces and corridors and also provide increased stability under the harsh conditions of a rocking boat.

If you are not sure which gauge, length, or type of battery cable you need, or if you are looking for high-quality battery cables, visit EWCS Wire and check out their incredible variety of wires and electrical components.

What Makes Marine Battery Cables and Terminals So Special?

Owning a boat requires a lot of work if you want to keep it in top shape for the next outing. Washing and waxing the fiberglass hull, cleaning up the bilge so you can spot leaking fluids, lubricating where needed, flushing your engine…

However, one of the most important things to be concerned about is making sure your electrical system works properly. You really don't want to have a power outage when you're away from the shore. Your electrical system not only keeps the lights on in your boat but also pumps life into your engines and powers vital instruments like your navigation and comms equipment.

These systems are relatively easy to maintain on land. However, the marine environment puts tremendous amounts of pressure on your electrical systems in the form of humidity, corrosion, constant vibration, and exceptionally common instances of “Murphy's Law” at play.

Being aware that anything that can go wrong will go wrong, boat owners are forced to be proactive and make sure they solve problems before they happen. So, installing dedicated marine battery cables and terminals is essential if you want your electrical systems to work regardless of what the open sea throws at it.

But, what's the difference between regular wire and marine battery cables and terminals?

In general, wires and cables should be able to carry a current load around an electrical circuit. The best material for this is copper as this material is a highly efficient conductor. However, copper is highly vulnerable to corrosion, meaning that any exposure to the marine environment will chew it up faster than you can say “ready to set sail”. Moreover, copper wires are usually too rigid, which means that the constant rocking of a boat can progressively loosen soldered connectors and terminals.

Marine battery cables and terminals are specifically made to withstand all these conditions and still be easier to install and maintain. Marine-grade wire has a higher strand count, which means that it is extremely flexible and can be driven through narrow and constrained environments usually found on boats. They are also more stable, even under constant vibration and movement. Each strand inside marine battery cables is individually tinned for maximum corrosion resistance, which gives them their typical silvery look.

On the other hand, marine battery terminals are solderless, reducing the amount of labor required to install or replace the wiring. You won't find the usual plastic or PVC sleeves found in automotive-grade terminals. These are replaced by nylon sleeves that provide increased crack, puncture, and corrosion resistance. Their conductors are not made of bare copper but from tin-plated electrolytic copper which reduces power loss, and increases corrosion resistance. They also provide unmatched mechanical connectivity through a tightly insulated wire crimp.

As you can see, there are important differences between automotive-grade wiring and marine battery cables and terminals. If you want to find marine-grade electrical supplies, we recommend EWCS Wire. They have everything you need for your next marine electrical project in one place. If you want to know more about their high-grade marine battery cables and terminals, call them at 800-262-1598 for further assistance.

Why Fire Alarm Plenum and Riser Ratings Are So Important

Fire alarm cable is of the utmost importance to public safety, as it allows the different nodes within a fire alarm system to communicate. If there’s a problem with the wiring and the system can’t communicate, it can’t relay important information about heat, smoke detection, or carbon monoxide to other nodes, smoke detectors, or alarms in the system.

Talk to any civil or electrical engineer about that and they’ll concur. That’s why all of the minute details associated with wiring should be understood - thoroughly understood - before attempting to complete plans or install wiring.

With that in mind, let’s take a closer look at two important fire alarm cable ratings - for riser-rated and plenum-rated cables.

What Is Riser Space? Riser space, as the name might suggest, allows for utilities to “rise” through a building. That is, it is the vertical space reserved for things like communication lines, water pipes, conduits, and of course, alarm cables, to be vertically distributed throughout a building.

Think of riser space as the “space between the walls” because, in most instances, that’s exactly what it is. It’s also typically sealed off to access from the inside.

As a result, riser-rated cables are typically built to lower or less stringent specifications than plenum-rated cables, but this is not always the case (see below).

What Is Plenum Space? Plenum space, unlike riser space, is space that is hollowed out between the floor and the ground, or more commonly, between a drop ceiling and the actual ceiling. While plenum space can also be used for water pipes and conduits, it is also the space in a building that is reserved for ductwork and HVAC.

As a result, it is possible for the contents of the plenum space to communicate with the rest of the building. That is to say, if there were, for instance, smoke in the plenum space, it could get into the living quarters of the associated floor.

Consequently, plenum-rated fire alarm cables (and other cables) must be much more resilient to heat and fire than riser-rated cable.

How Does This Affect Fire Alarm Cable? Since fire alarm cable must be safe for use around people and also resilient to fire in order to work, this has some implications for alarm cable specifications.

Generally speaking, all fire alarm cables should be high heat resistant, self extinguish, and not produce toxic smoke when burned. However, pllenum-rated cable must be more resistant to heat and fire than riser-rated cable because of the nature of plenum space. As a rule, you can use plenum-rated cable in riser space but not a riser-rated cable in plenum space.

Also, one thing to keep in mind is that there are also riser and plenum-rated conduits. If you use a plenum-rated conduit, it may be possible for you to use riser rated cable - but check with an electrical engineer to be sure.

What To Look For When Buying Marine Electrical Cables

Purchasing your first boat is a uniquely liberating experience. The thought of being able to sail away from worries, being alone at sea, spending quality time with your family aboard, or even traveling at leisure, are all ideas that cross most people's minds every once in a while. However, anyone with an IQ of room temperature knows that owning a boat comes with a new host of responsibilities that need to be properly taken care of if they want their dream to last. That's why I have prepared a short and sweet guide on what to look for when buying one of the most important onboard elements: marine electrical cables.

What Is Considered Marine Electrical Cable? Even the most barebones dingy today has some kind of electrical equipment on board, and they're no good if there is a risk of them breaking as soon as you lose sight of the coast.

Marine electrical cables are a category within the electrical wiring industry to designate cables specifically designed to withstand anything life at sea can throw at them. Regular cables used for homes and other commercial uses are designed for dry and static environments where they can remain safely out of sight for years or decades. Contrastingly, marine electrical cables are made with specific uses and conditions in mind to earn their stripes.

First, they should be corrosion resistant. While most cables have a protective jacket or insulator, only marine electrical cables have their conductive strands individually coated in tin or lead, making them impervious to corrosion.

Secondly, they must be flexible enough to pass through narrow spaces. Boats are known for posing challenging space restrictions, so having adaptable cables is a necessity so you can bend them to accommodate the demands of your ship.

Lastly, they need to withstand the rocking of the ship and constant vibrations. Stiff cables transfer vibration to connectors and cause them to become unstable. Marine electrical cables reduce this transfer and provide system stability even under heavy stress.

Factors To Be Considered When Buying Marine Wires Now that you know the importance of marine electrical cables, you need to make sure you are getting the right wires for the intended applications.

Make sure you know the amount of voltage your wires need to carry and the voltage drop. As current travels through a conductor the voltage drops, creating a measurable difference between input and output loads. Your cables should not have more than a 3% voltage drop.

Amperage is another factor you should consider. You need to take into account ambient average temperatures, gauge conductor dimensions, jacket temp ratings, and interior conditions.

Are Marine Electrical Wires The Same As Regular Cables?

In the world of electronics, there is a huge overlap between the different uses of electrical components in various industries. The reason is that anything powered by electricity needs wiring, and they are made according to widely general principles.

However, certain environments and uses can push electrical components to the limit, or prove to be extremely taxing for regular components made for all-around use.

Components that go onboard an open sea vessel must be able to withstand extremely harsh and prolonged conditions. This includes tools, work equipment, and electronics. As a general rule, always be ready to lose anything you bring on board.

The Key Aspects Of Marine Electrical Wire Some think that automotive wire is tough enough for marine use. In fact, automotive wire is specifically made to withstand extreme heat conditions, and be oil resistant. This might prompt many to assume that automotive and marine electrical wires can be used interchangeably. However, certain features make marine-grade cables more suited for their intended tasks.

One of the most obvious factors is that only marine electrical wires are specifically protected from the damaging effects of life at sea.

For example, marine-grade wire is usually larger than its advertised gauge size. Sometimes the dimensional difference can be up to 12%. This has to do with their added protection from elements. While copper, the main component of most wires, is relatively more corrosion resistant than ferrous metals, oxidation is still a major concern when on board. Perhaps you have seen the effects of corrosion on copper pipes at home. The distinctive green patina that forms around the affected zone serves as a protective coating in many instances, and some even like the aged look of verdigris copper. However, this patina will prevent electrical current from flowing freely.

As a solution, marine electrical wire is spun in thin strands of copper, but each of them is covered by a protective tin layer that protects the cable from the effects of corrosion for years.

The insides of a boat do not offer much room for onboard equipment. Moreover, the probability of water coming inside, makes it imperative to keep wires and electrical components out of sight. This often requires your wiring to go through very narrow and winding paths that demand extra flexibility. The copper strands inside marine electrical wires are thinner than those found in automotive cables. This means they are more flexible and less prone to breaking, offering added stability under conditions of extreme mechanical vibrations. The increased copper content makes sure your wires can comfortably carry the intended load.

To ensure stable connections, and prevent many of the dangerous incidents caused by faulty electrical connections, make sure you use high-quality marine electrical wire. Electric Wire and Cable Specialists is an online business with decades of experience in the industry. They carry a wide selection of marine electrical wires and accessories for boaters and experienced DIY enthusiasts looking for electrical components and supplies.

Why Are Security and Alarm Cables So Important?

Many appliances in our homes deserve more attention than what they usually get. That is the case of fire alarms, CCTV systems, motion sensors, keypads, and devices that make our homes and businesses safer but stay out of sight and out of mind for most of us. However, these devices are just as important as televisions or refrigerators.

Security cables are the unsung heroes among home appliances - they're not glamorous, they don't have a cool display, and you might never see them again after installation. But security cables play an essential role in our lives by ensuring that the various utilities we rely upon are safe and secure.

There are two kinds of security cables: safety cables and security cables. While they both enhance home or office safety, they provide that protection in different ways. Security cables are designed to accurately relay information between control and alarm systems. On the other hand, safety cables ensure that devices do not pose a fire hazard by preventing the transmission of electricity.

Most of the time, security and safety cables are used in tandem. When you wire a home or an office with CCTV cameras, security cables connect the cameras to the monitor. However, safety cables are needed to protect the system against fire hazards. If a cable that does not have the proper insulation is exposed to high heat, it can cause a fire.

The other common application for security and alarm cables is in fire alarms. Most alarm systems rely on several sensors to detect signs of danger from smoke or flames. Sensors are installed in areas where fires frequently occur, such as near a stovetop or a fireplace. They are connected to the main control panel with security cables, but those cables must also be combined with safety cables to prevent electrical hazards.

Safety and security cables use different insulation materials to protect against heat, so they offer very distinct benefits for appliances that face different risks of catching on fire.

Now, there are many options out there when it comes to choosing security and alarm cables. We recommend going with high-quality cables that come in the right variety depending on your needs. For example, you might need riser or plenum-rated cables.

Riser cables are used for vertical runs in a building, such as from a basement to the ground floor of an office. Plenum cables, on the other hand, are designed for horizontal runs through air ducts and plenums that serve as pathways for heating and ventilation equipment.

On top of that, riser cables tend to be more durable because they need to be able to maintain insulation standards in the event of a fire.

Security cables are designed to meet different standards for plenum and riser applications based on their electrical performance capabilities.

We find that Belden security and alarm cables are incredibly reliable and easy to install. They come both in plenum and riser varieties and have features that facilitate their installation, such as ripcords for fast jacket removal, and footage markings to eliminate the need for guesswork. EWCS Wires offers the widest selection of Belden security and alarm cable for all your needs.

Marine Battery Cables and Terminals: A Short Q&A

Is your boat’s electrical system on the fritz? Do you need to make a new connection to your boat’s batteries? Thinking of tackling the project on your own?

If you do, make sure you use the right tools and parts for the job - which includes dedicated marine battery wire for any wiring jobs or connections.

And in case you have any questions about marine battery cable and terminals, these are some of the most common.

What Is the Difference Between Marine Battery Wire and Regular Wire? Both marine battery wire and regular wire and used to carry a current around an electrical system, in the case of battery cable, as leads for a battery.

However, marine battery wire has two specific attributes that make it more suitable for the application than normal wire.

One is that it is not wire at all, but cable. “Wire” is a bit of a misnomer, actually, since a wire is a single-stranded conductor. Cable, on the other hand, is made of many fine braided conductors. Marine battery cable is made with an exceptionally high conductor strand count to make it more flexible.

The other distinguishing feature of marine battery cable is that it is specially treated to resist corrosion (see below).

Why Does Marine Battery Wire Look Silver? Marine battery cable, A.K.A. marine-grade cable, is typically made with a high number of tinned copper conductors - and each conductor features individual tin plating. This gives the copper a higher-than-average resistance against corrosion, which is a significant hazard in marine environments where corrosives like salt spray and battery acid could quickly inhibit an electrical circuit.

What Gauge Does Marine Battery Wire Need to Be? The gauge of your marine battery cables and terminals should match. Therefore, if your battery terminals are 14 gauge terminals, your cables should be 14 gauge battery cables. Some battery terminals are capable of accepting a range of compatible gauge sizes, so consult the battery manufacturer if you have any questions. It is also important to remember that a larger battery cable offers less electrical resistance and higher current carrying capacity.

Can You Use Automotive Battery Wire instead of Marine Battery Wire? It is inadvisable to use automotive battery cable in situations calling for the use of marine battery cables and terminals. While automotive battery cables are intended to be used as leads for batteries, they will either lack the flexibility or corrosion resistance necessary to make them serviceable in a marine environment.

Where Can I Buy Marine Battery Cables and Terminals? If you’re looking for the highest quality equipment you can find for your next marine electrical project, look no further than EWCS Wire at EWCSWire.com.

All of their marine battery cables are UL-listed and many of them are USCG and ABYC approved. They are also protected against corrosion and fatigue and also feature oil, gasoline, moisture, acid, alkali, and abrasion resistance.
