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?

SIZE BTU Starting Load
Amps @ 208 Volts 3 Phase
1 Ton 12,000 17
2 Ton 24,000 33

Furthermore, what size breaker is needed for a heat pump? The 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.

What size breaker do I need for a 4 ton heat pump?

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.

How many amps does it take to run a heat pump?

How much service space do you need? A single zone needs somewhere around 15 – 20 amps. While a dual or tri-zone will require 20-30+ amps.

How many watts does a 3 ton heat pump use?

As a general reference point, a 3 ton central air conditioner uses around 3500 watts per hour and a 12,000 BTU window unit uses about 1200 watts per hour.

How many amps does a 2.5 ton AC pull?

RLA is running load amps, your minimum ampacity is 19, and the min fuse size is 25. I would base it off that to start with, but you must also consider the indoor blower unit which is probably 120V and 3-7 Ampsfor 2.5 ton my guess is 3.5-4.5 Amps. So overall your looking at say 30 Amps.

Is 100 amp service enough for central air?

A 100-amp service is good for a home of less than 3,000 square feet that does not have central air-conditioning or electric heat. A home larger than 2,000 square feet that has central air-conditioning or electric heat probably needs a 200-amp service.

Can I run my heat pump with a generator?

In general, many of the larger portable generators are rated for enough starting and running wattage to power moderately sized heating and air conditioning systems. However, if you're using a smaller portable generator that you typically use to power a few things while tailgating, it likely won't power your system.

What size breaker do I need for a 3 ton air handler?

You could need a 60 ampere circuit breaker for the inside (air handler) unit. Less than 15 amperes for the blower itself and the rest for the back-up electrical heating elements. Update: I've been running on a 20A breaker on my 3 ton outside unit for the last few weeks and it is working perfectly.

What size breaker do I need for AC condenser?

If the AC unit says that it's breaker should be a max of 20A, then use a 20A breaker. However, just to be clear, you can't change out the breaker to match the unit if the wire sizes are still too small. Since it says to use a 20A, the wires should be 12 gauge or larger.

Can you use a 25 amp breaker with 12 gauge wire?

A 12 gauge wire is rated for 25 amps. NEC only allows for it to be protected at a max of 20 amps (unless following an exception for motor loads). I would divide the load and install a seperate circuit.

What size breaker do I need for a 220 air conditioner?

The breaker requirement is only dictated by the wire size. If you have to run a new line always use 12 gauge 20 amp as a minimum for a 220v circuit.

Which wire is used for air conditioner?

Cable Wiring for Air Conditioner Circuits
Like any other electrical circuit, air conditioner circuits are generally wired with nonmetallic (NM) cable. The wire gauge must be appropriate for the amperage of the circuit. For a 20-amp window air conditioner, 10-gauge wire is typically used.

What size breaker do I need for a 230 volt air conditioner?

The Circuit Breaker Size for a 230 Volt Air Conditioner
Kevin, according to the specs for the air conditioner the circuit that should be installed would be a 30 amp 230 volt circuit using 10/2 cable with ground. The circuit breaker for this air conditioner circuit should be a 2-pole 30 amp breaker.

What size breaker do I need for a mini split?

Use a 20A breaker and 12 AWG (or larger) wiring.
Because this is HVAC equipment, a 14 AWG circuit and 15A breaker is insufficiently sized.
