First, please know that my knowledge of anything electrical is next to nothing. This question is a bit stupid, but I'm still gonna ask it.
My 1937 4-room bungalow has individual baseboard heaters in each room - each with it's own dial from 1-10. No central heating. The breaker box labels say "heater" for the 4 rooms, but don't specify which goes to which (I'll test and fix that little problem when it's not so hot!).
So, my question is this - is it okay to just flip all the "heater" switches until I accomplish what I need to do - which is to loosen and get behind the one in the kitchen? Does it matter if they're off for any length of time if they're not being used?
TIA for the useful help I know I'll receive from all you helpful TOH folks.
