This variac has 5 connections for wires. A line diagram and wiring schematic of a basic single pole switch circuit with 2 lights. In the next split second the current will reverse direction and flow backwards from Load to Line, from the light to L1. The voltage across the neutral and the high-leg will be 208V. Additional lights can be added as shown below; Compare the wiring schematic with the photo. Above is a “4 Inch Square Nail On Box” or “4S Nail On” at the right is a “Single Gang Device Cover” also called a “plaster ring” or “mud ring” The mud ring has to mount to the 4S box to allow switches and outlets to be mounted. Question; What size screws are used to mount a switch to a switch box? Electrical current begins at L1 and flows through the black wire to the red wire nut connection #1 in the light box.
