What wiring do I need for a fan/light/night-light fixture?
I just installed one of these combo fan/light/nightlight fixtures in my bathroom.

We used a Leviton triple rocker switch like this one:


We used cable with 4 wires between the switch and the fixture.  The hot wire goes into the switch.  The neutral connects to one of the 4 wires, the other 3 connect to the switch.

At the fixture, the neutral is connected to the neutral wires for all 3 functions (if there are 3 wires, there might only be one), and the 3 switched wires connect to the other 3 functions.
