VT623301AJ tripping 15a breaker at panel at 10psi in tank

CH VT623301AJ. Doerr 4.5HP, 26G. I have limited knowledge with this stuff, so bear with me.


I have free spun the pump by hand and has little/normal resistance, the motor starts and runs free of issue on it's own.

The pressure switch turns on and off at desired psi, with an audible psssh at shut down. The check valve on the tank seems to be operating normally, as I removed the exhaust pipe from tank to pump with 80psi in the tank and no air seemed to be escaping.

At first I figured it was the start capacitor. So I replaced both from Grainger, no change.

The pump works with a max of 10psi in the tank, anything more than that and it will load up and pop the home breaker panel (15a).

Please advise if you are powering this VT623301AJ compressor with 120 or 240 volts?
