Electrical Wiring in the Home/Understanding Heat Pump Wiring


I have a Carrier 25HCB530A300, KFCEH3101C15, with TC-PHP-01 Comfort Touch-N-Go Heat Pump System in my home. My 200amp service has a total of three double-pole breakers to operate this system (2) 60-amp and (1) 30-amp. What I would like to know is what breaker controls what part of the system? What do each of the 60's do and waht does the 30 amp do? I have determined that one of the 60-amp's controls the thermostat and have downloaded the installation guides for each component but they fail to explain how they get connected to the house service. Can you help me understand how this is integrated? Thanks in advance!


Are those breakers double pole breakers each?

Are there two wires coming from the breaker? If so, they are double pole.

If you have two 60 double pole, one is for the electric heat back up (KFCEH3101C15).  

The 30 should be for your heat pump.

Take a closer look at the panel and let me know if those are double pole.
