I have two breaker "panels", one is a 200 amp panel for everything in the house, and a separate one (with a different meter) that is just for my electric cold water heater, right next to the other panel, with two 15 amp breakers on it (240v). Now obviously I want to have hot water when the power goes out, but I want to know if I can use the same transfer switch on both panels?
I am guessing no, since I am not hooked up to the same neutral and ground in that electric hot water heater breaker panel.
If I can't, does anyone know why someone would put a separate panel JUST for a water heater? We just moved in this summer, the house is only 15 or so years old too, and it looks like it was done at the time of building the house. Also the breaker panels are in the basement along with the water heater.
