There are numerous forms of electrical wire. Each different kind of electrical wire is designed for some other job. The wires even have different types of insulation and protection; this is exactly what makes each one of these perfect for some other application. There is THHN and TFFN wires that are much the same. You can also find the NM-B and Romex wires and also the MC Conduit cable. Most of these wires are fantastic for electrical work indoors and some of them could also be used outside, as well as in conduit.
TFFN and THHN
Both of these wire names are abbreviations. TFFN stands for thermoplastic insulation, flexible, fixture, and nylon coating. Even though the THHN means thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then toss in that a few of the THHN wires come even during a water, coal and oil resistant form, and also you get THWN wire. They're all single conductor copper wires you can use both indoors, outdoors plus conduit.
NM-B and Romex
Romex could be the Southwire model of an NM-B cable. The NM means non-metallic. Because of this rather than wire being incased in a metal jacket. The NM-B cable carries a PVC jacket round the multiple conductors it holds. This type of electrical wire is only able to provide indoors. The wire does not have enough protection on it to be utilized outside. The commonest use because of this type of wire is within insulated homes and buildings, running power from electrical boxes to outlets, appliance and lighting.
MC Conduit Cable
This sort of electrical cable is very different from the NM-B cable. That is because the MC Conduit cable is metal clad. These kinds of electrical cable comes with a aluminum interlocked armor jacket instead of the typical PVC. The aluminum jacket round the wires conductors is supposed to behave as a conduit so there will not the need for one if it's being installed. This design can be supposed to speed up mobile phone process, subsequently saving electricians and contractors both time and money.
These electrical wires may be used indoors as building wire. Most can even be used outdoors in conduit at the same time. Now despite the fact that all of these wires are somewhat similar, they're still different, to ensure the variation in applications. Make sure you have a look at all of your options to find the right wire for your upcoming job or project!
