I have a 1 1/2 hp single phase baldor motor on a Burr King grinder.
wired 115v draws 13.5amps.
The circuit is 20 amp with about 12 ft #12 romex from breaker to plug. 25ft extension cord also #12. Nothing else on the circuit.
Sometimes on startup it will start, get up to speed, run for about 15 seconds and trip the breaker.
Sometimes it will be running for a few minutes unloaded and trip.
I have never had it trip while grinding.
No smoke, no smell of anything shorting.
All connection look good and tight.
Any ideas?
