Electrical Wire Done Affordably
There are numerous forms of electrical wire. Each different of electrical wire is designed for another job. The wires even have different kinds of insulation and protection; this is just what makes each one of these ideal for an alternative application. There's THHN and TFFN wires which can be virtually identical. There are the NM-B and Romex wires and in many cases the MC Conduit cable. These wires are ideal for electrical work indoors and a few of which could also be used outside, and in conduit.
TFFN and THHN
Those two wire names are abbreviations. TFFN means thermoplastic insulation, flexible, fixture, and nylon coating. Even though the THHN stands for thermoplastic insulation, heat resistant, high heat resistant, and nylon coating. Then toss in that a number of the THHN wires come even just in a water, oil and coal resistant form, and you also get THWN wire. These are generally all single conductor copper wires which you can use both indoors, outdoors as well as in conduit.
NM-B and Romex
Romex is the Southwire model of an NM-B cable. Currently the NM stands for non-metallic. Because of this as opposed to the wire being incased in the metal jacket. The NM-B cable has a PVC jacket around the multiple conductors it holds. Now this form of electrical wire can only be used indoors. The wire won't have enough protection onto it for use outside. The most typical use because of this sort of wire is at insulated homes and buildings, running power from electrical boxes to outlets, appliance and lighting.
MC Conduit Cable
This sort of electrical cable is very different from the NM-B cable. The reason being that the MC Conduit cable is metal clad. These kinds of electrical cable comes with a aluminum interlocked armor jacket rather than typical PVC. The aluminum jacket across the wires conductors is designed to work as a conduit there won't be the need for one if it's being installed. This design is also designed to accelerate mobile phone process, in turn saving electricians and contractors both money and time.
These electrical wires may be used indoors as building wire. Most can also be used outdoors in conduit at the same time. Now even though many of these wires are somewhat similar, they may be still different, hence the variation in applications. Be sure to have a look at all of your options to find the proper wire for your upcoming job or project!
