The main service panel in my house has eight 2 pole breakers in it. It breaks down as:
2 40A breakers for the AC units
2 50A breakers for the furnaces
1 40A breaker for the stove
1 30A breaker for the dryer
2 30A breakers that are unlabeled, but have 10ga wire landed on both.
We have a gas water heater, so no need for 240V power there.
My question is this: Any idea what the two unlabeled breakers could be for? I cannot think of any other 240V loads. We do not have a subpanel anywhere, no hot tub, no RV plug, generator backfeed... I have them turned off now, but have not noticed a change in anything. I would like to repurpose one of them to feed a subpanel in my shed, but don't want to drop something in the house. Thanks in advance for the help.
