Installing a Window Air Conditioner Circuit
Why is our Air Conditioner Circuit Not Working? Installing and Testing Air Conditioner Circuit Wiring.
Wiring a Air Conditioner
- My husband is trying to install a Window Air Conditioner for his brother, in an older model mobile home.
- He’s not an electrician but has wired lots of things over the years, including our whole shop. Has wired lots of 220 AC, welder, compressor, etc.
- He installed a new 20A 220Volt circuit breaker in the panel box, attached the white and black wires to breaker, and the bare copper wire to ground, but we still have no power to the new AC outlet.
- We thought it might be a grounding issue, so we ran a ground wire from the box out to the ground off of the service box, but still no power to the outlet.
- We changed the 12/2 wire multiple times, and changed the circuit breaker multiple times. We even changed the breaker position in box multiple times, but still no power to outlet.
- The AC is fine, and it works when plugged in to our 220 outlet. Any advice?
Thanks for your time.
