I have a question regarding putting a 20 amp outlet on a 30 amp circuit. I'm replacing appliances in my kitchen, and there's currently a 30 amp, 240V, 3-wire + ground feed to the location where the oven is located, on a 30 amp, double pole breaker. I'm planning to install an electric oven (240V) and a microwave oven (120V). Can I split off a single 20 amp, 120V receptacle for the microwave oven from one of the hot feeds while maintaining 240V for the oven? Would using a GFCI outlet instead of a standard one increase the safety of this installation? Or am I going to be forced to run another line to the breaker box specifically for the microwave?
