    There are several types of electrical wire. Each different of electrical wire is perfect for a different job. The wires have even different kinds of insulation and protection; itrrrs this that makes each one of these perfect for some other application. There’s THHN and TFFN wires that happen to be much the same. And then there are the NM-B and Romex wires and in many cases the MC Conduit cable. Most of these wires are great for electrical work indoors and several ones may also be used outside, along with conduit.

    TFFN and THHN

    Those two wire names are abbreviations. TFFN stands for thermoplastic insulation, flexible, fixture, and nylon coating. Whilst the THHN represents thermoplastic insulation, heat resistant, high temperature resistant, and nylon coating. Then include that some of the THHN wires come even just in a water, coal and oil resistant form, and you get THWN wire. These are all single conductor copper wires which you can use both indoors, outdoors plus conduit.

    NM-B and Romex

    Romex will be the Southwire label of an NM-B cable. Currently the NM represents non-metallic. Which means rather than the wire being incased in a metal jacket. The NM-B cable features a PVC jacket across the multiple conductors it holds. Now this version of electrical wire can only be utilized indoors. The wire doesn’t need enough protection onto it to be utilized outside. The commonest use for this type of wire is at insulated homes and buildings, running power from electrical boxes to outlets, appliance and lighting.

    MC Conduit Cable

    These kinds of electrical cable is incredibly completely different from the NM-B cable. The reason is the MC Conduit cable is metal clad. This type of electrical cable comes with an aluminum interlocked armor jacket instead of the typical PVC. The aluminum jacket round the wires conductors is supposed to behave as a conduit there won’t be the need for one when it’s being installed. This design can also be meant to accelerate set up . process, therefore saving electricians and contractors both time and money.

    Each one of these electrical wires can be used indoors as building wire. Most can even be used outdoors in conduit also. Now though many of these wires are somewhat similar, they’re still different, therefore, the variation in applications. Make sure you check out your options to find the proper wire for your job or project!
