There are numerous types of electrical wire. Each different of electrical wire is ideal for another job. The wires have even different kinds of insulation and protection; this is exactly what makes every one ideal for a different application. There exists THHN and TFFN wires that are similar. There are the NM-B and Romex wires and also the MC Conduit cable. These wires are great for electrical work indoors and a few of these could also be used outside, and in conduit.
TFFN and THHN
These two wire names are abbreviations. TFFN stands for thermoplastic insulation, flexible, fixture, and nylon coating. While the THHN means thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then include that many of the THHN wires come even just in a water, gas and oil resistant form, and also you get THWN wire. These are generally all single conductor copper wires you can use both indoors, outdoors as well as in conduit.
NM-B and Romex
Romex will be the Southwire make of an NM-B cable. The actual NM stands for non-metallic. Because of this instead of the wire being incased inside a metal jacket. The NM-B cable includes a PVC jacket round the multiple conductors it holds. This sort of electrical wire can only supply indoors. The wire doesn’t have enough protection into it to be used 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
These kinds of electrical cable is very completely different from the NM-B cable. This is because the MC Conduit cable is metal clad. This type of electrical cable posseses 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 so there will not an excuse for one when it is being installed. This design is additionally meant to quicken the installation process, in turn saving electricians and contractors both money and time.
These electrical wires can be used indoors as building wire. Most could 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, therefore, the variation in applications. Ensure that you have a look at all of your options to find the appropriate wire for your next job or project!
