VEVOR 110V Bain Marie Food Warmer 8 Pan x 1/2 GN,Food Grade Stainelss Steel Commercial Food Steam Table 6-Inch Deep, 1500W Electric Countertop Food Warmer 88 Quart with Tempered Glass Shield

Does this unit stay on with a consistant 1,500 watts or is there somethin in it that tells it when the food has reached desired heat and then turn on and off as temp lowers

Does it have to have its own circuit breaker or would it work on a regular commercial outlet?

Can 110V/15A breaker handle 2000 watts

What plug does it come with? Is it 110 volt? Thanks Pat
