There are numerous types of electrical wire. Each different kind of electrical wire is ideal for an alternative job. The wires have kinds of insulation and protection; this is what makes each ideal for some other application. There is THHN and TFFN wires which can be similar. There are the NM-B and Romex wires and in many cases the MC Conduit cable. All of these wires are great for electrical work indoors and several of them can also be used outside, as well as in conduit.
TFFN and THHN
Both these wire names are abbreviations. TFFN is short for thermoplastic insulation, flexible, fixture, and nylon coating. As the THHN is short for thermoplastic insulation, heat resistant, high temperature resistant, and nylon coating. Then add in that a few of the THHN wires come even just in a water, coal and oil resistant form, and also you get THWN wire. These are all single conductor copper wires which can be used both indoors, outdoors and in conduit.
NM-B and Romex
Romex could be the Southwire model of an NM-B cable. The NM is short for non-metallic. Which means rather than wire being incased in the metal jacket. The NM-B cable features a PVC jacket round the multiple conductors it holds. Now this form of electrical wire could only be used indoors. The wire does not have enough protection about it to be utilized outside. The most prevalent use because of this sort of wire is at insulated homes and buildings, running power from electrical boxes to outlets, lights and appliances.
MC Conduit Cable
This type of electrical cable is extremely not the same as the NM-B cable. That is because the MC Conduit cable is metal clad. This kind of electrical cable comes with an aluminum interlocked armor jacket instead of the typical PVC. The aluminum jacket around the wires conductors is supposed to become a conduit there will not be the need for one if it’s being installed. This design can also be designed to quicken the installation process, consequently saving electricians and contractors both time and expense.
Each one of these electrical wires can be utilized indoors as building wire. Most could even be used outdoors in conduit also. Now even though these wires are somewhat similar, they’re still different, therefore, the variation in applications. Ensure that you check out your entire alternatives to find the right wire for your forthcoming job or project!
