There are various forms of electrical wire. Each different of electrical wire is good for some other job. The wires need different kinds of insulation and protection; this is just what makes each one ideal for some other application. There is THHN and TFFN wires that happen to be similar. And then there are the NM-B and Romex wires and also the MC Conduit cable. Many of these wires are perfect for electrical work indoors and some of these doubles outside, plus conduit.
TFFN and THHN
These two wire names are abbreviations. TFFN is short for thermoplastic insulation, flexible, fixture, and nylon coating. Even though the THHN stands for thermoplastic insulation, heat resistant, high temperature resistant, and nylon coating. Then throw in that a few of the THHN wires come during a water, gas and oil resistant form, and also 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 make of an NM-B cable. The actual NM is short for non-metallic. Which means as opposed to the wire being incased within a metal jacket. The NM-B cable carries a PVC jacket across the multiple conductors it holds. This particular form of electrical wire can only supply indoors. The wire won’t have enough protection into it for use outside. The most prevalent use with this sort of wire is insulated homes and buildings, running power from electrical boxes to outlets, lights and appliances.
MC Conduit Cable
These kinds of electrical cable is extremely completely different from the NM-B cable. The reason is the MC Conduit cable is metal clad. These kinds of electrical cable has an aluminum interlocked armor jacket as opposed to the typical PVC. The aluminum jacket around the wires conductors is designed to behave as a conduit there will not the need for one if it’s being installed. This design can also be designed to increase the installation process, therefore saving electricians and contractors both money and time.
Each one of these electrical wires can be utilized indoors as building wire. Most can also be used outdoors in conduit too. Now although all of these wires are somewhat similar, they’re still different, hence the variation in applications. Make sure you check out your entire choices to find the proper wire for your job or project!
