Caution: The bus bars in the load center I received would accept only 1 inch GE breakers. It has no provision for 1/2 inch breakers. It can be used for a maximum of 20 circuits using only 1" breakers. That means 20 120VAC or up to 10 240VAC or some combination that will get you less than 20 circuits. The one I received either had the wrong bus bars, the specs are wrong or have changed. I returned it because I needed 27 circuits. If 20 or less 1" circuits using 1" GE Breakers is enough, this is a good deal.
