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)].
To find out more about microwaves and range hoods, see our blog posts Does a home inspector check for dedicated circuits? and Is a range hood exhaust fan required in the kitchen? and Do microwaves require any minimum clearances around them? and What are the most common defects with over-the-range microwaves? and What is the maximum recommended height above the floor for an above-the-range microwave?
