I have added an outlet to a 3-way switch for my garage light by tapping onto the black hot wire into the switch. I am now however getting a reading of 48 volts at the outlet.
What is the correct wiring for adding an outlet to a 3-way switch?
you may have the wrong side of the switch. on a 3-way, there is an always-hot on one switch, and an always-load at the other. there are two "traveler" wires between them, one is hot one way, the other hot the other way the switches are thrown. you are probably taking power off the load (usually lighting) and the voltage drop is what the light allows you.
so the other switch has the hot, and this is not going to work.
you will need to find another unswitched outlet there, and pull a new wire from there.
sig: if this is a new economy, how come they still want my old-fashioned money?
That sure is a hard word to pronounce. Anyway thanks for the help. I think you are absolutely right. I am now heading for a hot source other than in a 3-way switch;
