I am installing a GFCI outlet. I think my house is 20 amp but I am not sure. Will it be a problem if I install a 15 amp outlet? I am using the outlet for a clothes dryer which plugs into an ordinary wall outlet.

You can put your 15 amp outlet on a 20 amp circuit, you just can't put a 20 amp outlet on a 15 amp circuit. So your clothes dryer is gas and just uses the ordinary outlet to power the drum and controls, right?

Thanks balllengerb1. My clothes dryer (aptartment size) is an electric and it does have an ordinary plug.

Wow, an electric clothes dryer that doesn't require 240 volts, have not seen one.
