Help with double vs single pole for reno
We are preparing for a DIY kitchen reno that includes adding some recessed lighting. Our panel is completely full but we discovered that some breakers are not being used. Specifically, we have a gas oven and behind that is an ancient plug for an electric oven. In the breaker box, the electric oven plug is powered by 2 double pole 50 amp breakers (see pic). What we were wondering is if we could replace those breakers with single poles (20amp singles preferably)? In the end, we will probably get an electrician out here to do the work but I'd like to know what to ask for and to be a little more educated about this before he starts work.
