Wall oven microwave combo
I am replacing a microwave wall oven combo with a separate microwave and wall oven in the same space. The old unit was wired on a 240/120 combo 30a circuit with 10-3wg. The original wall oven had an outlet on the unit that the microwave plugged into, and obviously the new single wall oven does not have this outlet. My plan is to get a new box and 120v outlet. I will wire the oven the same as the original except I will add additional wires to the wire nuts for one of the hot wires, the neutral wire, and the ground wire. I will connect these to the outlet that will be used for the microwave. Will this work, and is this the best way to do this? Can I use 12 gauge wire for this microwave outlet?
