Not to be critical but I am an electrician and it is a bad idea to use the breaker to the feeder circuit to start/stop a load. Every time you flip the breaker it weakens it a little more.
Excellent advice!!! The small independent repair shop where I used to work did that. Every night he would kill power to the compressor at the breaker. Worked okay for a year but then every time the compressor would turn on it would kick the breaker. Ended up replacing the breaker and installing a switch.
