A typical 240 volt 5 KW air handler generally uses a 30 amp

**breaker**and #10**wire**. The**2**-**ton heat pump**should have a data plate that specifies MCA (Minimum Circuit Ampacity) and MOCP (Maximum Overcurrent Protection).

Besides, how many amps does a 2 ton heat pump use?

AIR CONDITIONING & HEAT PUMP LOADS - TYPICAL | ||
---|---|---|

SIZE | BTU | Starting Load |

Amps @ 208 Volts 3 Phase | ||

1 Ton | 12,000 | 17 |

2 Ton | 24,000 | 33 |

**wire**is 8/2, and it is currently fed from a 60-

**amp breaker**(and has been for the last 7 years since the house was built). The

**heat pump**is 3 ton with 10kW of strip

**heat**. According to the nameplate, minimum

**circuit**ampacity is 74 amps, and maximum overcurrent protection device is 80 amps.

Also to know is, what size breaker do I need for a 2 ton AC unit?

As you can see, for the smaller **AC** the manufacturer specifies a wire **size** of 12 gauge minimum and a **breaker size** of 35 amps. Normally, for 12 gauge copper wire you'd need a circuit **breaker** of no more than 20 amps.

**4 ton** 13 SEER **heat pump** condensing unit - max 45 amps and min 26.4 amps. I'd probably go with a 40 amp since you won't find a 45. 5 **ton** 14 SEER **heat pump** condensing unit - max 60 amps and min 34.5. Air handler **breaker** sizes for both above units are max 15 amps and min 5 amps.
