Finding the Right Electrical Cable for Nearly Any Project

Electrical cables come in a variety of forms, all of which have their own unique uses and capabilities. But what kind of cable is ideal for each job? When choosing the ideal cable for a particular project, there are endless possibilities! In this article, however, there are three different types of cable that are going to be explored: low-voltage, optical fiber, and coaxial cables.

  • Low-Voltage Cable

Low voltage cables are usually created from plain flexible copper conductors that are bunched together. These cables are insulated and colored so they’re safe to use and easy to identify. The copper core wires are twisted together and then covered with a flexible form of high grade PVC, or polyvinyl chloride. These cables are used for a variety of products, from everyday appliances to small industrial machines.

  • Optical Fiber Cable

Optical fiber cables are great for electronic devices that need to carry and transport data. These cables are fairly common and are used in households and data centers around the world. Televisions, internet, and other complex electrical equipment use these wires and most people are already familiar with how they work. Optical fiber cables are also some of the most reliable forms of cable, thanks to their flexibility and efficiency.

  • Coaxial Cable

Coaxial cable is another commonly used electrical cable. This cable has an inner conductor which is surrounded by insulation. It connects with other devices used a tube-like conducting shield. The coaxial cable gets its name because both conductors run parallel to each other on the same axis. Many households and commercial businesses use this form of cable, however, its most common usage is to connect a TV to an antennae.

Understanding what each type of cable does best is a great way to decrease the uncertainty of an electrical project, particularly if you’re doing it yourself. Also remember that electrical accessories are available which can make a potentially frustrating project even easier. If you’re uncertain about what type of cable or accessory is needed for your project, it’s best to ask a trusted and reputable expert to assist you.

 

Copper MC Cable Information

MC CableMC stands for Metal Clad which is derived from the aluminum armor that wraps around the conductors. Copper strands are used to conduct electricity, THHN insulation is used to protect the copper and aluminum armor is used as a jacket instead of duct for indoor applications. Copper MC cables also have industry approvals that allow it to pass inspection per the NEC code.

Copper Strands

Electrical cables are those used in homes and buildings either bringing power to the building or supplying smaller amounts of power throughout the building. Electrical cables are typically manufactured with stiff copper strands because it helps during the installation process. Pushing flexible cables through conduit and duct is difficult because it will bunch and get stuck. Stiff MC cable can be used indoors without conduit, outdoors and underground when in conduit or raceway. The only environmental application not safe for MC cables is directly underground because they don’t have enough protection.

In order to install a copper MC cable underground you will need to get the additional PVC jacket. The construction is exactly the same with an additional PVC jacket to create a water tight jacket and a cable available for direct burial applications.

THHN THWN Insulation

The term “insulation” is used to describe what covers the copper strands and the term “jacket” is used to describe the outer wrapping that covers all of the wires inside the cable. The MC cable conductors are covered with THHN THWN approved insulation. THHN stands for Thermoplastic High Heat Nylon which describes the materials used and protection it’s exerting. So, depending on the amount of conductors your cable has, 2, 3 or 4 THHN wires are bundled together and wrapped with aluminum interlocked armor.

Aluminum Interlocked Armor

The metal clad jacket, named aluminum interlocked armor, is very different compared to standard types of electrical cable jackets. It was designed to be used indoors for applications that require a cable and conduit together. MC cable is approved as a “cable and conduit” in one for indoor applications. It will pass inspection with approved THHN THWN wires and an approved metal clad jacket. MC cables can also be used outdoors and in conduit underground when necessary.

Please speak to your wire and cable supplier before making an electrical cable purchase. They can help match the most cost effective cable for your installation based on the environment it will be placed in. Getting an approved cable at the right price is what most contractors, electricians and installers want when they’re in search for copper cables.

Copper Strands in Electrical Wire

Copper is the best conductor of electricity and the most widely used commodity in electrical wire and cable. Different sizes of copper are twisted together to create varying flexibility in gauge sizes used across the industry.

Bare copper ground wire doesn’t have any insulation covering the copper and it’s normally one solid strand. A 30 awg copper strand is more flexible than a 2 awg copper strand because of the size. The bigger it is the less flexible it can be, similar to thin a metal rod being easier to bend than a think rod. Therefore, when discussing the flexibility of a wire or cable the size of the copper strands play a big part.

THHN electrical wire comes in the option of solid or stranded copper depending on the amount of flexibility you need for your application. One might need it to be flexible so that it can bend around corners while another might need it less flexible to push it through conduit easier. The PVC insulation and nylon coating also limit the amount of flexibilty of THHN building wire.

Welding cable is known to be much more flexible in the industry for two reasons. The first is the 30 awg copper strands compared to THHN’s 19 strands that get larger as the wire gets larger. The next is the rubber insulation which is much more flexible, and expensive, than PVC. With a rubber jacket there will be almost zero chances of it cracking or splitting during installation unlike THHN wire.

Talk to us about your needs so that we can help you find the correct product at the right price for you. You may think you need welding cable but after discussing your situation with us we might find that you can use something less expensive without compromising the application. We’re an ISO 9001 certified company that not only wants to, but needs to continuously improve in order to keep our certification.

The Importance and Safety of Service Entrance Cable Type SER

Wires and cables are primarily used to transmit electrical energy from its main source to the various users such as manufacturing industries, factories, business offices as well as the home.  But before the electricity can reach the end user, the edifice that will utilize it needs to have a service entrance where the electrical devices and wires of the home or edifice and of the electrical company meet. The energy have to pass this device since it serves to meter, protect and distribute the electrical supply to the various branch circuits placed strategically inside the house and/or edifice.  Service Entrance Cable Type SER is a type of cable that is used widely consumers due to its simple but sleek design.

Service Entrance Cable Type SER contains wires that are made of copper.  The cable contains three wires, two of which are insulated in different colors while the last one is completely bare for easy identification.  The two insulated wires are the primary transmitter of electrical power while the bare or the neutral wire serves to support and/or neutralize the other two wires.  These wires are then covered with rubber and/or plastic.  An outer cover is also installed to protect the wires from damage since it will be constantly exposed to the harsh elements.  That is the reason why the insulators that are used in these cables are sturdy enough to withstand fluctuating temperatures.  There is a need for these wires and of the cable as a whole to be free from any defects.  This is to ensure the safety of its user and to avoid any damage and/or malfunctioning.  Thus, this type of cable has materials that can withstand wet and dry locations. 

In installing Service Entrance Cable Type SER, proper procedure should be followed based on the guidelines provided by the NEC and the wiring and protection law that is implemented in the state where you are currently located.  These guidelines are precautionary measures to prevent accidental electrocution and or to avoid other hazards that individuals may experience if the said wires are haphazardly installed.  Contractors and consumers should to purchase these type of wires from accredited manufacturers and sellers to ensure the high quality of materials that is used. 

Online sellers and hardware stores are selling this type of cable at a very competitive price.  There is a standard color of the insulator for this type of cable for easier identification.  You need to check the wire to determine the uniform thickness from end to end.  You can purchase this cable by meter or by bulk.  Manufacturers may ship the material to you for free if you purchase a minimum amount from them.  You can ask the seller to cut and strip the cable at a specified length before sending it to you.  You can also ask them to tin dip the wire if you do not want a cable with fray edges.  Inquire from the seller the exact day of delivery for there are some sellers who have a delivery time of two weeks from the date of purchase.  If you want faster delivery, you need to negotiate with them.

Copper Electrical Cable Differences

Copper electrical cable is very expensive, but the real differences in price actually comes down to the insulation type more than the copper. Copper is the conductor of electricity in all copper electrical cables and the price of copper changes everyday. However, Romex 6/3® has the same amount of copper as UFB 6/3, so why is the price different?

A 6 awg wire is a 6 awg wire whether it’s in a Romex NMB® jacket or a tough underground PVC jacket. That means each 6 awg wire would be the same price if they were both stripped of all insulation. A UFB underground insulation was manufactured to be used without conduit. So the jacket needed extra protection in order to last as long as an electrical cable in conduit.

In order of the amount of protection Romex® comes first, MC cable second and UFB cable third for electrical cables. Even though each of these cables have different levels of protection they all still have THHN THWN as the wire conductor insulation, so what changes the fact that some have more restrictions?

Romex® cable has a bare copper uninsulated ground wire, but lacks a strong enough jacket to protect it outdoors or in conduit. Moisture, gas, solvents and other fluids can puncture the jacket and hit the bare ground wire leaving it only available for wiring indoors.

MC cable is manufactured with all THHN wires and a THHN insulated green ground wire. That allows MC electrical cables to be used outdoors and in conduit because it resists all water, moisture oils and gases without an uninsulated ground wire in the way.

UFB cable is manufactured as an underground electrical cable which is also known as direct burial in the wire and cable industry. It still has an uninsulateed ground wire but the PVC jacket is engineered tough enough to protect all of the wires even when used directly underground.

In order to find the cheapest cable possible you’ll want to first speak to an electrician to let you know the awg size of the cable you need. This will prevent you from getting a size too big and paying more money than you need to. The second thing you want to do is make sure you’re not getting too much insulation that you may not need. Getting UFB cable when you’re using conduit anyways is a waste of money. You should get MC cable which is cheaper and manufactured for use in conduit.

We offer exact cut lengths on all of our electrical cables and THHN wire because in the contractors, engineers and installers like to have the exact length they need to avoid waste of small lengths at the end of each spool. We also offer free shipping on orders over $250 so that you don’t have to negociate deals with trucking companies to get spool of wire or cable.

Please call us if you need any type of wire, cable or heat shrink tubing as we’ve been a stocking distributor for over 25 years.

Electrical and Electronic Wire Products Navigation

We decided to change the navigation on our website to better group each type of electrical and electronic wire by keyword for our customers and visitors. We know it will help our customers find what they’re looking for much faster based on how they search for wire and cable.

Before anyone gets to our wire and cable distribution website they must first type a phrase into the search engine. Once the searcher visits our website we can see the phrase that was entered into the search engine, which we then analyze, and alter our website accordingly.

If we get 100 visits based on the term “electrical wire” being typed in then we need to make sure they land on a page with multiple electrical wire items available so that they find what they need as quick as possible. We analyzed each landing page of our website so that we could offer all the products that our visitors are looking for.

We also reworked the side bar product listings because we’ve been adding more products to our website and need to organize it better. Each product is listed based on its keyword rather than our part number to allow our visitors to easily find what they need.

We’ve also added more pictures so that it reassures our customers that they’re buying the correct product online. Sometimes it can be hard to realize you’re buying the right type of electrical wire online because all you can see is the vender part number and about a million different products to choose from.

When you’re on WesBell’s website you’ll find that every page is unique and specific to one item only. You’ll be able to see all of the spcifications, approvals and guage sizes of that type of wire or cable. Please call when you have any questions because we openly give out our phone number instead of hiding it in one of the back pages.

Electrical wire is the biggest product listing on our website including Romex®, UFB, SER, SEU, THHN and MC wire and cable. Each type of electrical wire has similar characteristics and most commonly used in the electrical field carrying current from your electrical panel to all of the lights, outlets and appliances in your home. Bigger awg sizes of electrical wire are used to carry current from the street to your electrical box, which is then distributed throughout your home with smaller types of wire and cable.

Electronic wire and cable includes hook up wire, high temperature wire, multiconductor cables, fire alarm cable, shielded and unshielded cables. Electronic cables are used mostly with indoor electronics such as stereos and appliances. When you take off the back panel of anything electronic you’ll see wires harnesses and cables that need to each have specifications to meet for that application.

Some electronic cables can be basic PVC / PVC cables, some need higher voltage, some need a shield, some need higher temperature and some need to be more flexible than others in order to be approved for that application. These are the types of keywords we like to list our products under because our customers don’t know our part numbers or the manufacturers part numbers. All they know is that they want a “high temperature cable with 3 conductors and a shield” so we list our products accordingly.

Take a walk through our website to see the difference because you’ll find it’s much easier to use than other wire and cable websites that list their products by their own part number. Call us if you have any questions so that we can help make sure you have the best type of wire or cable for your application at the cheapest price possible.
