    There are various varieties of electrical wire. Each different of electrical wire is good for another job. The wires even have kinds of insulation and protection; this is exactly what makes each one of these ideal for a different application. There’s THHN and TFFN wires that are similar. And then there are the NM-B and Romex wires and in many cases the MC Conduit cable. These wires are perfect for electrical work indoors and a few of which may also be used outside, as well as in conduit.

    TFFN and THHN

    Both these wire names are abbreviations. TFFN stands for thermoplastic insulation, flexible, fixture, and nylon coating. As the THHN means thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then include that some of the THHN wires come even during a water, gas and oil prices resistant form, and you get THWN wire. They are all single conductor copper wires that can be used both indoors, outdoors as well as in conduit.

    NM-B and Romex

    Romex will be the Southwire model of an NM-B cable. The actual NM stands for non-metallic. Which means as opposed to the wire being incased in the metal jacket. The NM-B cable has a PVC jacket throughout the multiple conductors it holds. Now this type of electrical wire can only be used indoors. The wire doesn’t have enough protection into it to use outside. The most typical use for this kind 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 extremely not the same as the NM-B cable. This is because the MC Conduit cable is metal clad. This sort of electrical cable has an aluminum interlocked armor jacket instead of the typical PVC. The aluminum jacket around the wires conductors is designed to behave as a conduit there will not an excuse for one when it’s being installed. This design is additionally supposed to accelerate the installation process, subsequently saving electricians and contractors both time and cash.

    Each one of these electrical wires may be used indoors as building wire. Most could even be used outdoors in conduit also. Now although all of these wires are somewhat similar, they may be still different, to ensure the variation in applications. Make sure to look at all of your options to find the correct wire for your job or project!
