I have a 5 ton Carrier heat pump that is about 10 years old. It is a split unit with backup heat. I have only lived here for about two months and the previous knows nothing about the unit. The installers have gone out of business.
In my breaker box there are three separate supplies for the system.
One 60A breaker goes to the outside unit and is marked "heat pump"
Two 60A breakers go to the inside unit and one is marked "central unit" and the other is marked "electric heat".
I can't understand why there are two breakers feeding the inside unit. Would a single 60A breaker supply the fan motor and the emergency heat?
If I don't need two breakers, I could use one as the power supply for a welding recepticle that I plan to install near the inside unit and it would save me a lot of work and expense.
