The breaker type be it a single pole or double pole will depend on what voltage the air conditioner operates on. Once the voltage is established, the sizing of the breaker depends on what the current draw of the air conditioner is.

The type and size of the breaker to use on an air conditioner will depend upon the specifications of the air conditioner. This information will be found on the conditioner's nameplate. If the voltage is 120 volts a single pole breaker will be used. If the voltage is 240 volts a two pole breaker will be used. The amperage of the breaker should be within the amperage stated on the nameplate. Some air conditioners are of such a size that they can not be plugged in and have to be hardwired. These installations should be done by a qualified electrician and he will know the wire size and size of the breaker required to protect that size wire.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances
always use a test meter to ensure the circuit is, in fact, de-energized.

What size breaker goes with a 15kw heat strip?
60
What Size breaker for 6 gauge wire?
You need a 60 amp breaker.
What size breaker do you need for a 3 Ton heat pump?
My 3 ton geo unit uses a 30 amp breaker. That is probably more than adequate because it also is for the vertical loop pumps in the ground. The back-up heat strips however, use a 60 amp breaker (on my system.) I'm not sure but I would say yours probably needs that too. Good luck!
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
What size wire and breaker do you need to run a 9000max watt generator?
If it is a portable generator the breaker should be self contained within the generators panel. If the generator is a stationary standby unit a voltage has to be stated to calculate the conductor size and hence the breaker size to protect the conductor. Amps = Watts/Volts.
What size of central and heat unit do you need for 916 square feet home?
What size of central and heat unit do you need for 916 sq ft?
How do you calculate the watts of a central air and heat unit?
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.
What size breaker goes with a 15kw heat strip?
60
What size breaker do you need for 9000W at 440V 3 phase delta?
50amp but if considering the breaker cannot withstand starting current you need to size the breaker up.
What Size breaker for 6 gauge wire?
You need a 60 amp breaker.
What size wire do you need to wire a 200 am breaker box?
6
What size wire do you need for a forty amp breaker?
8 AWG is typical.
What size breaker do you need for a 3 Ton heat pump?
My 3 ton geo unit uses a 30 amp breaker. That is probably more than adequate because it also is for the vertical loop pumps in the ground. The back-up heat strips however, use a 60 amp breaker (on my system.) I'm not sure but I would say yours probably needs that too. Good luck!
What size breaker do you need for two 60W bulbes 110 volts?
It is not the number of bulbs that you worry about. It is the wire size that is your concern. If the circuit is wired with AWG 12/2 wire then use a 20 amp breaker. If it is wired with a AWG 14/2 wire then use a 15 amp breaker. You are protecting the wiring with the correct size breaker.
What size breaker do you need for 9000W at 440V 3phase?
This formula will give you the amperage I = kw x 1000/1.73 x E x pf (pf = power factor). Take the amperage and multiply it by 125%. This will give you the breaker size that you need.
