Hello all, my question is this. Last fall I removed the breaker and all electrical from an old wood electric furnace I had to update to gas. The breaker is 125 amp square D on a 200 amp service square D panel. I installed a 15 amp for the new furnace in a fresh new slot. Now I am left with a large hole in the bottom of the panel where the old one used to go. It took up the bottom 4 slots. What are the options for filling it in?
