Cooper light switch wiring diagram how to#
The ground wire is connected to the light fixture lead and is pigtailed to the box, if it is metal. Diagram shows how to wire 3-way switch that controls a light, and single-pole switch that controls a fan. The cable run from the light fixture requires a 2-wire cable with ground. At the light fixture, completing the wiring is simply a matter of connecting the black and white circuit wires to the matching wire leads on the light fixture.Once again, the white neutral wires are simply joined together, and the grounding wires are joined together with pigtails connecting the switch and to the box, if it is metal. However, at this second switch, the common screw terminal is connected to a black hot wire that leads onward to the light fixture. At the second switch box location, the wiring is similar to the first switch, with the traveler terminals connected to the traveler wires coming from the first switch.Because switches do not have white-colored neutral wire connections, the neutral wires at the switch boxes are simply joined together so they pass through, onward to the light fixture box.This provides two alternate pathways for hot current to flow between the switches-this is what allows the switches to turn the lights on and off in a flexible manner.
The black and red wires are "travelers" and are connected to the traveler screw terminals on the two switches.
