There are several varieties of electrical wire. Each different kind of electrical wire is perfect for a different job. The wires have different kinds of insulation and protection; itrrrs this that makes each one of these great for another application. There is certainly THHN and TFFN wires which can be very similar. Then there are the NM-B and Romex wires and also the MC Conduit cable. All of these wires are perfect for electrical work indoors plus some of which could also be used outside, as well as in conduit.
TFFN and THHN
These two wire names are abbreviations. TFFN represents thermoplastic insulation, flexible, fixture, and nylon coating. Even though the THHN represents thermoplastic insulation, heat resistant, high temperature resistant, and nylon coating. Then add in that a number of the THHN wires come even during a water, gas and oil resistant form, and you get THWN wire. They are all single conductor copper wires you can use both indoors, outdoors plus conduit.
NM-B and Romex
Romex is the Southwire make of an NM-B cable. The NM represents non-metallic. Because of this as opposed to the wire being incased within a metal jacket. The NM-B cable features a PVC jacket around the multiple conductors it holds. The following type of electrical wire could only provide indoors. The wire does not have enough protection into it to be used outside. The most typical use for this kind 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 not the same as the NM-B cable. The reason is 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 round the wires conductors is meant to act as a conduit so there won’t be any excuses for one when it is being installed. This design is also intended to quicken the installation process, therefore saving electricians and contractors both time and cash.
These electrical wires can be utilized indoors as building wire. Most could even be used outdoors in conduit as well. Now though many of these wires are somewhat similar, they may be still different, therefore, the variation in applications. Make sure to check out all of your alternatives to find the appropriate wire for your upcoming job or project!
