Three-way switch wiring diagram with the LINE and the LOAD inside separate switch boxes. LINE power is delivered to the first switch by using a two conductor cable with a bare or green equipment grounding conductor. The LINE wire is connected to the "Common" terminal on the 3-way switch. A three conductor cable goes from one switch box to the other switch box. From the second switch box a two conductor LOAD cable goes to the light fixture or ceiling fan. The black LOAD wire is connected to the "Common" switch terminal and the two white neutral wires are simply joined together with a wirenut.
