The primary difference between 14-2 and 14-3 Romex wire lies in the number of conductors contained within the cable. 14-2 Romex has two insulated conductors (one black, one white) and a bare ground wire, making it suitable for standard circuits. In contrast, 14-3 Romex includes three insulated conductors (black, red, and white) plus a bare ground, allowing for multi-wire branch circuits and more complex installations, such as three-way switches.
