Amperage question

My home was built in 1961. I have a 100 amp panel. I noticed I have six 20 amp circuits, but nothing but 15 amp receptacles. Is this a problem? Never had any problems in 30 years.

As long as your cabling is 12 gauge, you are fine.

Are you saying that all the 120vac, 15A receptacles in the house are powered by the six 20A breakers/fuses and there are no other loads on the six 20 breakers/fuses? A 15A receptacle is only UL tested and approved up to 15A. Changing the receptacles or the breaker/fuse for compatibility will be dictated by the connecting wire size.

All modern 15 amp duplex receptacles are UL rated for 20 amp pass-through and are specifically permitted to be on 20 amp circuits. Only a single (simplex) receptacle all by itself on a 20 amp circuit would need to be rated 20 amp.

Given the house was built in '61 I would suspect 15 amp breakers were replaced with 20s without changing the wore size. Look around to see if you can find any cable jackets you can read the size off.

Each outlet on the duplex receptacle is rated up to 15A. The whole unit is rated for use on either a 15A or 20A circuit.

You should never find a tool, appliance, or other device that has a 15 amp plug and that draws more than 15 amps after a brief startup time interval.
