Our dryer circuit has a 30A breaker and 50A receptacle. I've read that if any of this was new work, it would not meet current code. Example:

Can I connect 12 AWG wire to 10 AWG in a junction box?

When was this requirement codified?

  • Are you sure it has a 50A receptacle? No dryer cord would ever be sold that is 50A, except maybe for commercial dryers in a laundramat. It would require a double failure of both the person who fit the receptacle choosing a very wrong receptacle, and the person who selected the dryer cord selecting a cord that is specifically not sold as a dryer cord.

    @Harper The previous homeowner could have installed a 50A receptacle, and new owners could have modified their dryer to suit the receptacle. It's not obvious to non-electrical folk, that different receptacle configurations have any meaning.

  • @Harper The brown plastic cover of the surface mount receptacle is embossed with 50A, UL and GE. It accepts plugs with three flat blades. Looks like this: i.ebayimg.com/images/g/aT8AAMXQW7VREb-y/s-l1600.jpg

  • @Tester101 We purchased the dryer new from an appliance store, and it was installed new by the store. We haven't modified it.

  • @April I was responding to Harper, explaining how this could have easily happened. The answer to your question, sort of, is... Not all electrical work is inspected (unfortunately). Replace the receptacle (or have it replaced by a professional), with the proper 30A receptacle.
