carrier air handler / heat pump electrical requirements
 
Guys in the HVAC side told me to post this here as well

Im having a new system installed and to save some cash i have removed the old furnace and heat pump and im going to be doing the wiring from the breaker box to the new unit. The installer has given me power wiring documentation, however im not certain how to interpret what he wants. Can anyone tell me in "laymans terms" what size breakers and what gauge wires i should run? Here is the system being installed:

1-Carrier model FB4CNF036, “Comfort” air handler.
1-Carrier 15 KW electric heater package.
1-Carrier model FILCCAR20 media air cleaner.
1-Carrier model TP-PHP” thermostat and control wiring.
1- Carrier model 25HBC336A003, 3ton, up to 13 SEER, “Comfort” heat pump unit 1-New copper refrigerant tubing package to run from the new air handler to the new heat pump unit. This will also include a TXV refrigerant flow meter.
1-New 220 volt rain tight disconnect for the new heat pump.

This is the wiring document he provided me with:

Any way to rescan and make it larger and more clear, the data is there-but I cannot read it.

If not we can do a google search and get it.

It states on the plate of the equipment, Max Breaker size. Does not matter if the disconnect outside is a 50 amp or 60 amp disco, what matters is the breaker inside.

Unless the unit says MOCP is to be fuses only. Quite common.

Save it as a pdf.

Just to have enough power for the 15 kw heater you will need a 70 amp circuit. How large of an electric service do you have?
