A friend of mine told me when he wires outlets in series, he takes the (2) black #12 wires and twists them together with a #14 pigtail wire that connects to the receptacle. He says it is much easier to work with the receptacle with the #14 wire. Same thing with the white and ground wires. Is it ok to do this since the wires are in the same box as the 15A rated receptacle?

A 15 amp rated duplex receptacle is allowed on a twenty amp circuit, 14 awg in this situation can not be protected at any more than 15 amps.

The problem with reducing the wire to #14 is that it allows backstabbing a device that is designed to prevent this on anything but 15 amp circuits. (UL white and green books)

If the device is connected with the screws, I don't see why this would be necessary.

Just my opinion.

The breaker must be rated to the smallest size wire on the circuit. If these circuits are protect by a 15 am breaker then he is OK. If they are protected by a 20 amp breaker then he is wrong.

Per Joed's response - the code section restricting the conductors to be sized no smaller than the circuit breaker is - (1999) 210-19(b) - 'conductors of branch circuits...shall have an ampacity of NOT LESS THAN the rating of the branch circuit.

210-3 - says the rating of the circuit is based on the rating of the circuit breaker.

240-3(b) restricts a #14 to a 15A circuit breaker.
