3 Way Switch Diagram Power At Light. This is the 3 wire cable which you must have to wire a 3 way. Light before switches power at light fitting below is a step by step process of connecting the wires with power at the light fitting.
In the ceiling light fixture electrical box one black wire from a 3 way switch gets connected to the black load wire on the light fixture. Two three way switches control one light with the electric power coming through the first switch flowing to the second switch and then to the light fixture. With these diagrams below it will take the guess work out of wiring.
In the ceiling light fixture electrical box one black wire from a 3 way switch gets connected to the black load wire on the light fixture.
Three way light switch with power feed via the light. Bring the hot black wire from the power source to the common terminal black of the second switch through the ceiling box. In the ceiling light fixture electrical box one black wire from a 3 way switch gets connected to the black load wire on the light fixture. In this light switch wiring diagram the power feed joins the circuit via the light fixture where a two wire cable c2 runs from the light to the first 3 way switch sw1 and a 3 wire cable c3 joins the two switches.
