An average household circuit will trip all the time with this one. All our outlets are rated at 20 Amps. Only our dryer which is at 240V is rated at 50. A Rating of 3,750Watts means you need a 50 Amps 110V circuit to safely run this thing. It should not be sold for American household. I was hoping they have the 240V but no, they sent me the 110V grinder, so it is useless.
