A:Answer This unit does not need it's own circuit. Mine is plugged into one of the kitchen outlets and I have not had any issue with blowouts. As for the heat, the instructions does have some recommended space constraints on how close side/top walls/cabinets should be. The biggest one is the top side which need almost 8 inches to be safe. The front door does not get to hot but the left side (metal) does get fairly hot. Not enough to burn you, but you(grandkids) probably do not want to touch for long. Underneath does not seem to be an issue even the back does not seem to put out much heat. Please note, it is like an oven so when the front door is open, it does put out a lot of heat and trays, food, etc are going to be hot if you are cooking/microwaving/grilling on high heat.
