What Do Line and Load Mean in Wiring?

Distinguishing between line and load isn't always necessary. For example, a conventional wall switch -- which is a single-pole, single-throw switch -- works equally well whether you attach the live circuit wire -- line-- to the top brass terminal or the bottom because the switch has only two positions -- open or closed.The terminal connections are directional on a double-throw switch, on the.
