Romex Types Determine your need to determine the type of Romex needed Gage Size of the wire (common = 12 or 14) 2 wire 1 black, 1 white, and 1 bare/green ground wires 3 wire 1 black, 1 red, 1 white, 1 bare/green ground wires
Wire Types There are 4 basic types of wire Black wire = hot White wire = neutral Bare/Green wire = ground Red = hot
Wiring Rules Neutral wire goes without interruption to every place in the circuit where current may be used Neutral wire is connected to the silver-colored terminal. The neutral wire is white.
Wiring Rules Black or red wire is always connected to a brass- colored terminal. Black or red wires carry “hot” power or current from the source to the devices within the circuit
Wiring Rules The green, or bare, grounding wire is connected to the grounding terminal (green screw) of a grounding-type electrical fixture. All wires must be spliced or connected to a terminal screw in each box. Only one wire is allowed to be fastened under a terminal screw.
