I was told that on the 12/2 wire I need a 20 amp breaker, but in looking at different 20 amp breakers I see also other nos. You're probably looking at a 3.5 ton unit, so you'll be in the 30-40A (10-8 AWG) range. The plug will also show how many wires are required for the circuit, for example 4 prongs would indicate a 3-wire circuit with a ground wire. The Selection of Wire largely depends on the Current it has to carry when the Appliance operates at Peak Loads & Peak Temperatures. Home Circuit Breaker While most original condenser fan motors only have three wires, it’s very common for replacement condenser fan motors to have four. I am installing a 2.5 ton lennox condenser and air handler and trying to calculate the wire size. Kevin,  you should not use 12/2 cable for this circuit because it will be too small because the circuit will be limited to 20 amps and the 18.9 amps required for this load is over 80 percent of the rated load for the 20 amp circuit.
