Adding another 240v line
Wondering if anyone can help. I have a 80amp sub-panel. I already have one 30amp 240v line for my air compressor, but wondering if its possible to add another 240v for a window a/c heater combo. It says 20amps on the unit. And 20amps for the lights and 20 amps for plugs. What can i do?
How many spaces are left in the feeder? When you say the unit, I take it you’re talking about the heater/ac unit combo requiring 20 amps. Is this correct? And what are you referring to for the plugs? Receptacles/outlets for a particular room? And lights for a particular room? Please elaborate. The 240 volt heater/ac unit is going to require a 20-amp two pole breaker and you need to feed it with 12-3 w/g. The black is one hot, the red is the other hot, the white is the neutral and the bare is the ground. Then you should be good to go.
