Does a combination microwave and range hood need a separate dedicated circuit?
Sunday, December 6, 2020
A combination microwave/hood cannot be connected to the either of the two required kitchen small appliance receptacle circuits because it is not a countertop (portable) appliance, per National Electrical Code [NEC 210.52(B)(2)]. It’s a fixed appliance. Also, all the manufacturer’s manuals for microwave/hoods that we have seen specify a dedicated circuit, preferably 20-amp, and the NEC requires following manufacturer’s installation instructions for listed and labeled appliances [NEC 110.3(B)].
