wire for central air (cooling only)
The wire for a central cooling system should be #10 or #12? I found it is #12 romex cable here. Is it correct?
How about refregerator?

The unit will have a data plate with the circuit and overcurrent protection sizes.
A refrigerator is typically fine on a 15 amp dedicated circuit.

There are two circuits required for central air.
One for the air handler. Some are 120 v and some are 220 v. Usually a 15 amp (#14) circuit.
The condenser runs on 240 v and will usually require at least #10 wire on a 30 amp breaker. If the condenser is on the opposite end of the home from the panel......I'll use # 8 to keep the voltage drop to a minimum.
