What would be the correct amperage for a dedicated microwave circuit breaker?
I am using Romex 12-2 from the panel to the outlet which is about 15 feet, the microwave is a over the range unit with about 1000 watts.
Help on this matter is well appreciated.

Thanks

David

I believe a dedicated microwave circuit is overkill, but whatever. 12-2 can be run to a 20 amp breaker, but if you are running a 20 amp circuit to only a single outlet, you will need to ensure that you are using a 20-amp receptacle. You will want to check with your inspector on whether it must be a single (as opposed to the typical duplex receptacle.) If it's mounted high on the wall (in a cabinet), and is a single, it probably won't need gfci protection. Otherwise, it probably will. 2 minutes on the phone with an inspector will be easier than screwing it up and having to fix it later.

Volts X Amps = Watts

120Volts X Amps = 1000 Watts.

Amps = 8.33

All you need is 14-2 wire on a 15 amp dedicated breaker.

Right now it is on a 15 amp breaker but there is other things on that circuit, it trips when too many things are running at the same time.
I think the 15 amp will do, but I wanted to get input from more experience folk, like you guys.
I thank you guys very much for your replies.

Just a note, the code calls for the microwave to be on it's own circuit. From a common sense side, running to your panel to reset breakers is a pain, with it's own circuit it won't trip unless there is major problems.

Please quote the code section where this is stated I've never heard of this one but then again I am still a student.
