Electric power Wire Made Simple

There are several kinds of electrical wire. Each different kind of electrical wire is good for a different job. The wires have even different types of insulation and protection; this is just what makes every one great for a different application. There's THHN and TFFN wires that are virtually identical. There are the NM-B and Romex wires as well as the MC Conduit cable. Many of these wires are great for electrical work indoors plus some of which can also be used outside, and in conduit.


Those two wire names are abbreviations. TFFN stands for thermoplastic insulation, flexible, fixture, and nylon coating. While the THHN represents thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then toss in that many of the THHN wires come even just in a water, gas and oil resistant form, and you also get THWN wire. They're all single conductor copper wires you can use both indoors, outdoors plus conduit.

NM-B and Romex

Romex will be the Southwire label of an NM-B cable. The NM represents non-metallic. This means that instead of the wire being incased in a metal jacket. The NM-B cable features a PVC jacket across the multiple conductors it holds. The following form of electrical wire could only provide indoors. The wire doesn't need enough protection into it to be utilized outside. The most prevalent use for this type of wire is insulated homes and buildings, running power from electrical boxes to outlets, appliance and lighting.

MC Conduit Cable

This kind of electrical cable is quite not the same as the NM-B cable. This is because the MC Conduit cable is metal clad. This kind of electrical cable comes with a aluminum interlocked armor jacket instead of the typical PVC. The aluminum jacket across the wires conductors is supposed to become a conduit so there will not a need for one if it's being installed. This design can also be designed to quicken cellular phone process, in turn saving electricians and contractors both time and cash.

Every one of these electrical wires may be used indoors as building wire. Most can even be used outdoors in conduit as well. Now despite the fact that many of these wires are somewhat similar, they are still different, therefore, the variation in applications. Make sure to look at all your options to find the proper wire for your upcoming job or project!
