New pump and motor combination installed. Pump comes on for two seconds then trips the breaker. All electrical seems to check out, running 230V on 230 Line, wired correctly, phase is same as previous motor. Replaced circuit breaker (2 pole 15 amp), checked impeller and it moves, still nothing. The only difference is the new motor is 1 1/2 HP and the previous was 1 HP. Have to imagine its a bad motor, but it's brand new so I want to ensure I'm not missing something electrical.
Thanks and I do appreciate your time and assistance.
