There are several varieties of electrical wire. Each different of electrical wire is perfect for another job. The wires need different types of insulation and protection; this is just what makes each one of these suitable for some other application. There exists THHN and TFFN wires that happen to be virtually identical. And then there are the NM-B and Romex wires and also the MC Conduit cable. These wires are ideal for electrical work indoors and several of them may also be used outside, and in conduit.
TFFN and THHN
Both these wire names are abbreviations. TFFN means thermoplastic insulation, flexible, fixture, and nylon coating. As the THHN stands for thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then toss in that a few of the THHN wires come even just in a water, gas and oil prices resistant form, and you get THWN wire. These are all single conductor copper wires you can use both indoors, outdoors plus conduit.
NM-B and Romex
Romex may be the Southwire label of an NM-B cable. The actual NM stands for non-metallic. Which means that as opposed to the wire being incased in the metal jacket. The NM-B cable includes a PVC jacket around the multiple conductors it holds. This particular type of electrical wire are only able to be used indoors. The wire does not have enough protection on it to be used outside. The commonest use just for this form of wire is at insulated homes and buildings, running power from electrical boxes to outlets, lights and appliances.
MC Conduit Cable
These kinds of electrical cable is incredibly completely different from the NM-B cable. This is because the MC Conduit cable is metal clad. This kind of electrical cable posseses an aluminum interlocked armor jacket as opposed to the typical PVC. The aluminum jacket across the wires conductors is supposed to behave as a conduit there will not be any excuses for one if it is being installed. This design can also be designed to speed up mobile phone process, consequently saving electricians and contractors both time and money.
Most of these electrical wires can be used indoors as building wire. Most can also be used outdoors in conduit at the same time. Now although all of these wires are somewhat similar, these are still different, which means the variation in applications. Ensure that you take a look at your options to find the right wire for your job or project!
