Load vs. line wire
A delayed timer switch I am installing requires that a different wire be fastened to the "load wire" than to the "line." How would I determine which is which (both come into box at same side). Can I use a multitester?

Yes. Check continuity.:jester:

the terminal labeled line is the power coming into the timer and the line goes to the unit being turned on by the timer

Continuity between which wires coming out of the box?

There is no terminal or label on the wires coming from the wall box, I know which wire coming from the switch is which. The black load wire from the wall box and black line wire are the ones I can't tell apart.

The LINE wire would be the one with voltage on it, the load, well would be the device the line is suppling to...

Yes. Check continuity

I assume that this guy:jester: means you were joking?

Line side is the one with voltage. There could be continuity on either side.

Line = in, load = out.
