5hp CH Compressor pressure switch trips breaker
(Round top, tx)
5 HP Campbell Hausfeld air compressor
I just replaced the pressure switch on my 5hp CH compressor as it would not shut off and when building pressure would open the pressure relief valve,
My problem is that after installing the new switch it immediately trip breaker when i put power to it.
Suspecting that it would be on the motor side, I disconnected the leads to the motor. Tried this and it still trips breaker.
Breaker doesn't trip when I switch the pressure switch to off, but when I turn it to on, it immediately trips.
I am suspecting that the brand new pressure switch is defective.
I would expect that the switch is defective, it's been wired wrong, or it may not be rated for the voltage, John.
Based on what you have written I see no other options.
