    There are numerous forms of electrical wire. Each different of electrical wire is designed for some other job. The wires need different types of insulation and protection; this is exactly what makes each ideal for a different application. There is THHN and TFFN wires which can be much the same. Then there are the NM-B and Romex wires and even the MC Conduit cable. These wires are ideal for electrical work indoors and several of them could also be used outside, as well as in conduit.

    TFFN and THHN

    Both of these wire names are abbreviations. TFFN is short for thermoplastic insulation, flexible, fixture, and nylon coating. Whilst the THHN represents thermoplastic insulation, heat resistant, high temperature resistant, and nylon coating. Then add in that many of the THHN wires come even during a water, gas and oil prices resistant form, and you also get THWN wire. They are all single conductor copper wires you can use both indoors, outdoors along with conduit.

    NM-B and Romex

    Romex is the Southwire label of an NM-B cable. The actual NM stands for non-metallic. Which means as opposed to the wire being incased within a metal jacket. The NM-B cable has a PVC jacket across the multiple conductors it holds. This particular type of electrical wire is only able to be used indoors. The wire doesn’t need enough protection about it to use outside. The most prevalent use with this form of wire is within insulated homes and buildings, running power from electrical boxes to outlets, appliance and lighting.

    MC Conduit Cable

    These kinds of electrical cable is quite completely different from the NM-B cable. That is because the MC Conduit cable is metal clad. This kind of electrical cable has an aluminum interlocked armor jacket as opposed to the typical PVC. The aluminum jacket round the wires conductors is meant to work as a conduit there will not be an excuse for one when it is being installed. This design is also intended to speed up cellular phone process, in turn saving electricians and contractors both time and money.

    These electrical wires can be utilized indoors as building wire. Most could be used outdoors in conduit as well. Now even though many of these wires are somewhat similar, they’re still different, which means the variation in applications. Make sure you take a look at all of your choices to find the appropriate wire for your next job or project!
