The main panel contains: one 50A 2 pole for the range, one 60A 2 pole for the electric furnace, one 30A 2 pole for the electric water heater and one 2 pole 40A for the interior subpanel. It is an older, small rental house, all electric. The landlord had called me to check it out. Before I report back to him I will call the utillity for a usage history. I think they are just using the furnace plus the WH is outside plus they are probably taking longer hot showers in the winter. By the way the water heater is new.
