I replaced a painted-over simplex receptacle on a 120 volt 20-amp circuit with a 15-amp simplex Nema 5-15.

Only after I had closed everything up and was picking up the pieces (yes, it came out in pieces) of the old receptacle did I realize it was a Nema 5-20 simplex.

I found this out by looking at the round plastic face of the receptacle that had broken off when I pried the old paint-gleopped coverplate off the box.

It was too late by then to go back to the Home Depot store to get a 5-20 (and what's to bet they don't even have them in-stock *mad*). All the normal hardware stores were closed.

Must I replace the Nema 5-15 simplex with a 5-20?

It only powers a 110-volt 15-amp air condtioner during the summer. During the winter it's occasionally used for light duty appliances...like portable radios, a lamp or the occasional TV set.

Thanks.
