You can avoid both problems by wiring the outlet circuit with a 12-gauge wire, which is optional if the controlling breaker and all the outlets are rated for 15 amps. If the breaker is rated for 20-amps, however, you don't have a choice, because the electrical code never permits you to use a 14-gauge wire on 20-amp circuit.

The outlet-addition methods we show here are based on the most common wiring (14-gauge wire on a 15-amp circuit) and an 18-cu.-in. box (typical inside dimensions are about 2-in. x 3-1/4 in. x 3-in. deep).
