Circuit for OTR Microwave

davehoNovember 27, 2009

I'll be installing an over the range microwave where there is currently a simple vent hood. I know I need to run a dedicated 20A circuit, no problem there. The confusion is this. The installation instructions show the microwave being plugged into a single 15A recepticle. I thought a 20A circuit required a duplex 15A recepticle or a single 20A recepticle. I intend to use a single recepticle as I have no need for a duplex. The recepticle will be placed in the cabinet above the microwave. Is there an exception for this situation? The microwave has a 15A plug.

Thanks.

A 20 A single receptacle will cost more than a 15 A duplex.

Just use a 15 A duplex.

It's convenient to have a duplex receptacle up there in the cabinet, a lot of times people have devices that need to be plugged in to charge a battery that can be stored inside the cabinet.

I don't know the current codes - but if the microwave calls for a 15amp circuit are you really not allowed to install a dedicated single 15amp outlet for it?

Absolutely, what else would you install? But I think you have a typo in there. What you're asking is if you can install a 15 amp receptacle on a 20 amp circuit. The answer again is yes. The logic is that you can plug a lower demand appliance into a higher amp circuit. Certainly you could use a 20 amp receptacle but they're typically more expensive so why waste the money.

It actually comes down in many cases to the exact wording of the installation instructions for the MW.

They almost always 'recommend' a dedicated 15 A circuit (or more) for home size units.

A very few commercial models 'require' the dedicated circuit.

What I was questioning was the OP's assumption that he _had_ to run a 20amp circuit for a microwave oven that called for a 15amp circuit.
