Forgive me for asking what I'm sure has been asked many times---I didn't find it in the search.
I have a 240 volt circuit with a double 20 amp breaker and 12/3 with ground wire. I assume that either black or red wire with an excess of 20 amps will trip breaker ( both throws are tied together). The circuit is dedicated to an air compressor. In the 240 box, I want to pigtail off the black, white and ground wires for a 120 outlet. This sounds too easy so it must not be possible or against code. In either case, I'll access a 120 outlet----a much harder task because of location.
Against code or not possible?
