I have a 220v pump that has two terminals. They are connected to the circuit breaker with both hots, the neutral isn't connected to anything on the pump.
I'm trying to hook up a controller (relay) for a thermostat. I thought I knew how to hook it up, but it didn't work out so well (I fried the transformer in the relay box, which I don't really understand since it's rated for 220v).
I think the pump controller needs to be connected to the neutral with one hot connected directly to the pump, and the other side being switched by the relay.
Is that right? I'm hoping to avoid more smoke!
