Electrical Wire Made Easy
There are many different varieties of electrical wire. Each different of electrical wire is designed for an alternative job. The wires even have kinds of insulation and protection; this is what makes each perfect for an alternative application. There is THHN and TFFN wires which are virtually identical. And then there are the NM-B and Romex wires as well as the MC Conduit cable. These wires are perfect for electrical work indoors and some of these can also be used outside, and in conduit.
TFFN and THHN
These two wire names are abbreviations. TFFN means thermoplastic insulation, flexible, fixture, and nylon coating. Even though the THHN is short for thermoplastic insulation, heat resistant, high temperature resistant, and nylon coating. Then throw in that a few of the THHN wires come even during a water, oil and coal resistant form, and also you get THWN wire. These are all single conductor copper wires you can use both indoors, outdoors as well as in conduit.
NM-B and Romex
Romex may be the Southwire make of an NM-B cable. The actual NM stands for non-metallic. Which means rather than the wire being incased in a metal jacket. The NM-B cable carries a PVC jacket round the multiple conductors it holds. The following form of electrical wire is only able to be utilized indoors. The wire won't have enough protection onto it to be used outside. The most prevalent use because of this sort of wire is insulated homes and buildings, running power from electrical boxes to outlets, lights and appliances.
MC Conduit Cable
This type of electrical cable is very different from the NM-B cable. The reason being that the MC Conduit cable is metal clad. This type of electrical cable comes with a aluminum interlocked armor jacket rather than typical PVC. The aluminum jacket across the wires conductors is meant to behave as a conduit so there will not the need for one when it's being installed. This design can also be designed to accelerate mobile phone process, therefore saving electricians and contractors both time and expense.
Every one of these electrical wires may be used indoors as building wire. Most can even be used outdoors in conduit too. Now despite the fact that all of these wires are somewhat similar, they are still different, therefore, the variation in applications. Make sure to take a look at all your options to find the proper wire for your job or project!
