Our electric bill has been running pretty high even though it hasn’t been that cold and we’ve been supplementing with wood heat. Decided to track down the culprit and hooked up an energy usage monitor to one of our 5 sub panels. Gonna check the other 4 over the course of the next few days.
It has 200 amp service. It’s a pretty unusual setup, all original to the house which was built in the early 70’s. It would probably be prohibitively expensive if you did it the same way now. It was just way overkill to begin with.
