I have a Harbor Freight dust collector (SKU 59726) - it's a 2HP 14A 110V single phase motor. It has been running for several years, and has not been abused (just well-used). However, it now trips its dedicated, non-shared breaker about 3 seconds or so after starting, and I would like help figuring out why. The starting capacitor looks OK. Cables look good. The motor spindle turns freely. Do not recall seeing any magic smoke, or hearing unusual noises. Appreciate thoughts on how to debug, or should I just bite the bullet and get another one?
EDITS:
- Regular breaker - not GFCI. Why do I think it's the motor and not the breaker? Because I connected the motor to a completely different outlet somewhere else in the house, and exactly the same thing happened (again, non-GFCI).
- Instructions are here: https://manuals.harborfreight.com/manuals/59000-59999/59726-193175483607.pdf It says: Electrical Rating 120VAC / 60Hz / 14A 2HP, Single Phase Speed 3450 RPM Bag Capacity 35 Gallon Bag Filtration Ratio 5 Microns Inlet 4″ Air Flow 1550 CFM
There does not seem to be a plate on the motor itself.
- The specific request is: what can I do to stop the motor from tripping the breaker, is there some adjustment on the motor that I can make? Or does my issue mean that the motor has somehow just "died" necessitating a replacement?
