1 Answer. Type NM-B cable first began to be manufactured with color-coded jackets in 2001 to aid in identification of the conductor size.
What is the difference between 12 2 and 12 3 Romex?
The designation 12/2 indicates AWG 12 wire with two conductors (AC hot and AC neutral), 12/3 indicates AWG 12 wire with three conductors (two AC hot and AC neutral). Both designations also typically include a smaller bare copper earth ground conductor.

What type of wire is in Romex?
Romex Wire. Romex wire is made out of two or three THHN wires combined with a grounding bare copper wire. Like the THHN wires, Romex wire can’t be used outside because of its minimal PVC jacket protection. However, these wires come in larger sizes than the thinner THHN wires; 14/2 and 6/3 are used widely as electrical wire,…
What is Romex wire used for?
Romex is used for most lighting and outlet circuits in your home. Romex will be labeled with “12-2” or “12-3”. The first number indicates the gauge of the wire.
What is the difference between Romex and conduit?
Conduit has one big advantage over ROMEX® wiring and that is flexibility . While ROMEX® is available in a number of sizes, the insulated wires are all white, black and red. Using conduit, it is possible to use any color wire and implement color coding schemes not possible with ROMEX®.
Does all Romex have a ground wire?
Romex® Wire Information. Romex® electrical cable is a multi conductor THHN cable that has an optional ground wire. Romex® NMB is made with a thin PVC jacket manufactured as an indoor only cable which also excludes it from conduit use.
