Appliances question

[infinity]

So are you going to change the plug from a 15 to a 20 on a listed appliance or are you going to install a duplex so you can use a 20 amp breaker to meet code?

This is the key question.

Can't you just use a single 20 amp receptacle with the 20 amp OCPD and a 15 amp plug?

It is that simple, we had all apparently forgotten that a 15 amp plug would fit in a 20 amp single outlet! I had to look at one.

Ok so a 20 amp receptacle (duplex), 20 amp OCPD is ok? I like this the best.

Or a 20 amp single outlet.

Or a 20 amp single outlet.

Seems we got to the 20 amp circuit out of fear that a dedicated 15 amp circuit to match the factory cord and plug would trip the breaker.

Do we now have to size the OCPD for an appliance with a factory cord and plug to the name plate or by the factory cord end that is supplied with the appliance ?

It's certainly common for appliances with 15 amp cords to be plugged into 20 amp circuit/outlets. I don't know of a restriction regarding a single appliance on a dedicated circuit. Anyone?

I don't know of any restrictions either.

It's just that in this case the OP was not comfortable with installing the appliance on a circuit rated for the cord and plug that came with it.

Question: so regardless of what an appliance draws as long as long as it's up to 16A, You can simply put this equipment on a 20A duplex outlet with a 20A circuit?

The whole point of it all is to protect the branch circuit wiring.

You could even us a 15 amp OCPD with a 20 amp single receptacle and a 15 amp plug. Unconventional but code compliant.

Follow up, if a manufacturer recommends a 30 amp OCPD for a 12 amp motor appliance, does the receptacle have to be 30 amp rated as well with #10s?
