I have a 240 volt hot tub with a 50 amp circuit going to it and would like to use the same wire run to power a 240 volt single phase air compressor.
I want to make sure, obviously, that I don't damage either unit, so I want to get this right.
As I understand it, the compressor's 2 "Line" leads are going to be the 2 "hot" ones, and I won't use the neutral (white) wire to hook up to it. My spa has all 3 wires (plus the ground) going into the panel.
Will I have a problem if I "T" off the 2 hot leads to the compressor? I don't really have much money and would like to avoid hiring an electrician to do this, but I will if I must. I do a lot of the basic electrical work here at my house, so I have no problem making the connections, just understanding the different voltages when they get over 120v.
BTW I live in the US, if that makes a difference.
Also, what is the recommended way to put a switch on the compressor circuit?
