| My kitchen has a 20 amp appliance circuit--12 ga wire and 20 amp breaker, | but all of the outlets on the circuit are 15 amp outlets. Is this something | I should be concerned about? I.e., should I replace all of the outlets with | 20A?
The 15 amp receptacles, if they are modern UL listed devices, are rated for
20 amps current, including a total of 20 amps between each outlet of duplex devices, and passing 20 amps between the upper and lower screws for passing power through to the next device.
Do be aware that if you want to actually meet current electrical code, the receptacles in the kitchen and bathrooms do need to have the 20 amp outlet configuration (NEMA 5-20R) to allow you to plug in a 20 amp appliance (and you have to have at least 2 separate circuits of them for 40 amps total capacity in the kitchen).
