In a house recently built, the electrician had a 15 Amp rated outlet that on the back reads #14 AWG wire for the push in connection or #14 or #12 AWG wire to be used on screws. He then put this on a 20 Amp circuit. Can a 15 Amp device be put on a 20 Amp Circuit? To me, the overcurrent device should be rated to the weakest link in the circuit, which would be the 15 Amp rated outlet.
