Circuit Breaker Size for Air Compressor
I am about to wire my new shop area and I have my first air compressor. It has 13amps stamped on the plate (it is a 110v unit). Should I run a dedicate circuit (12/2) with a 15 amp breaker to protect the motor or use the normal 20 amp breaker I was planning for all the 110v outlets?

Per Table 210.21(B)(2) of the 2002 NEC, the maximum cord-and- plug connected load to a 15 amp receptacle is on a 15 or 20 amp circuit is 12 amps. The maximum on a 2o amp circuit with a 20 amp receptacle is 16 amps.
You need to install a 20 amp circuit with #12 wire to a 20 amp rated receptacle.
