I have seen some that say a 15 amp circuit. Many don't require an individual circuit but recommend it. If the mw is a countertop then the NEC will not be affected as the small appliance branch circuit will handle it unless one decides to run a circuit. In that case it must be a 20 amp circuit but if it is built in as a range hood then it may not necessarily require a 20 amp circuit

As far as I was concerned this was a mythical microwave and we were discussing codes.

It's going to be tough wrapping those #10's around the receptacle screws. Besides they're not designed for that.

We have to do that all the time and I pretty sure all devices are required to accept 10 AWG on the screws.

I think the only recs that are not listed to accept 10 are the cheapos. Pretty much all of the Spec grade or better is- and its easier to just use the plates on those for that thick wire.

It's not fun with #12, I can't imagine having fun with #10's not to mention stuffing the wires into a 1 g box

You're right. I forgot about the pressure plate commercial grade ones.

:D

Tell me about it, we might have 5 solid 10 AWGs on a duplex, however there will be a 4" sq deep box with a single gang plaster ring on it for the room.

No way I'm putting that many #10's on a receptacle, that thing is getting pigtailed with wago's. :happyyes:

Not only that, a cheap resi grade duplex will probably break trying to stuff it in.

Again, not thinking out of the box, I assumed in this thread that we were talking about residential work. I probably wouldn't come prepared with a 20A commercial grade receptacle if I were doing a residential kitchen

Any other types that require special wiring you will need to know the specs up front during the rough. I agree, you are not required to install a 20A circuit but again, if you have some $$ in the job I would run #12

Unless the run is over 125 feet, why would you?

Yes, for a counter top. An over the range will do fine on a 15 amp circuit.

Yes, but the point is only if it is a non-SABC receptacle. It is dependent on the receptacle/circuit classification as well as the microwave type.

Then #14 is sufficient :thumbsup:

If we're running a 15A circuit to a cabinet for an above range microwave unit, does the receptacle have to be a single or can it be a duplex ? Singles are generally a bit more $$ but I don't carry them on the truck. If a single is required is it acceptable to snap off the tab on the hot side and,in effect, make it a single ?

How many of you guys are seeing residential microwaves with 20 amp plugs on them? I have not seen any.

If they have a 15 amp plug a 15 amp circuit is not risky.

That said, if it is in a kitchen I agree with smart$ it needs to be 20.

hmmm, what about a 1875 watt hair dryer that uses the non-20A cord cap? this wattage exceeds 15A bc rating so it would need a 20A ckt. just because the device has non-20A cord cap does not mean a 15A bc will suffice.

i believe you look at the yoke. if it carries one recept then thats a single. more than one on the yoke then its not a single.
