There are numerous forms of electrical wire. Each different kind of electrical wire is good for another job. The wires need kinds of insulation and protection; this is exactly what makes each one of these great for an alternative application. There’s THHN and TFFN wires which 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 a few ones doubles outside, as well as in conduit.
TFFN and THHN
Both these wire names are abbreviations. TFFN means thermoplastic insulation, flexible, fixture, and nylon coating. While the THHN represents thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then add in that many of the THHN wires come even in a water, oil and coal resistant form, and you get THWN wire. These are all single conductor copper wires which can be used both indoors, outdoors as well as in conduit.
NM-B and Romex
Romex is the Southwire model of an NM-B cable. Now the NM stands for non-metallic. Which means that rather than wire being incased within a metal jacket. The NM-B cable carries a PVC jacket across the multiple conductors it holds. This sort of electrical wire can only supply indoors. The wire doesn’t have enough protection about it to use outside. The most typical use for this form of wire is at insulated homes and buildings, running power from electrical boxes to outlets, appliance and lighting.
MC Conduit Cable
This kind of electrical cable is very not the same as the NM-B cable. That is because the MC Conduit cable is metal clad. This type of electrical cable has an aluminum interlocked armor jacket rather than the typical PVC. The aluminum jacket around the wires conductors is supposed to act as a conduit there will not an excuse for one when it’s being installed. This design is also designed to quicken set up . process, in turn saving electricians and contractors both money and time.
Most of these electrical wires may be used indoors as building wire. Most can even be used outdoors in conduit as well. Now even though all of these wires are somewhat similar, they are still different, which means the variation in applications. Be sure to have a look at your options to find the right wire for your job or project!
