What size amp circuit breaker should be used for a air conditioner?

In the USA, a National Electrical Code specifies things like circuit breaker sizes. The purpose of the circuit breaker is to protect the wiring (which is usually in a metal or plastic conduit, or in its own plastic insulation, and also is usually hidden in the wall, ceiling, or floor). The size of the circuit breaker (such as 15-amp, 20-amp, 30-amp) depends upon the size of the wiring.
Wire guage sizes (in USA) are typically 14 awg (for lighting and light-duty circuits up to 15 amps), 12 awg (bigger than 14 awg, for power outlets as well as lighting circuits up to 20 amps), and larger sizes for special purposes.
Most modern kitchens have two or more 12 awg circuits for the purpose of providing power to appliances such as toasters, mixers, etc. A 20-amp circuit breaker would protect a 12 awg wiring system designed to carry 120 Volts and 20 amps (amperes).
For safety, you must determine the size of the wiring in order to decide which size circuit breaker will protect it.
15-amp circuit breaker for 14 awg wiring (which is easy to bend with finger tips) 20-amp circuit breaker for 12 awg wiring (which is hard to bend with finger tips) 30-amp circuit breaker for 10 awg wiring (which is very hard to bend with finger tips)
The appliances and other items that you plug into an electrical outlet rely upon their own fuses or other design features for protection. The circuit breaker protects the wiring to prevent fire. This is IMPORTANT. Do not use a larger circuit breaker than the wiring can safely handle.
AWG = American Wire Guage Smaller numbers are for bigger wires. 6-awg is about as big as a wooden pencil. 30-awg is about as fine as a human hair.
I would add this: do yourself a favor, make 12 gauge wire your standard when putting in any new wiring (unless you are going higher than 20 amp circuit) . Don't mess with 14 gauge at all. The cost difference is peanuts.

∙ 14y agoAll 110v air conditioners should have their own 20 amp dedicated line. Larger in wall air conditioners may require a 220v outlet to work. Check the owners manual of the air conditioner you have for specific electrical requirements.

∙ 14y agoUnless it is a very unusual refrigerator 15 A is more than enough. If you look at the nameplate it should tell you exactly what the refrigerator draws. The name plate could be anywhere but the most common places are: at the bottom of the front with the door open, on the outside in back, inside the refrigerator.

∙ 14y agoThe National Electric Code requires all kitchen appliance circuits must be 20 amp circuits and ground faulted. It also requires a minimum of two appliance circuits in new residential construction. 20 amp circuits require the use of # 12 gauge wire. Ground faulting can be accomplished by the use of a GFCI circuit breaker in the panel or a GFCI receptacle installed as the first device in the circuit.

∙ 10y agoFor the 120 volt outlets on the wall use a 20 amp breaker wired with AWG #12 wire. The circuit must be GFCI protected. Any 240 volt outlets must be wired according to what they will be powering.

What size circuit breaker for a 1 ton air conditioner unit?
About a tenth of a ton.
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 amp circuit breaker should be used for a home entertainment system?
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
Number 10 thnn copper wire.
What size amp breaker for a 220V air conditioner?
a 2p 20 amp should work fine for a single 220 air conditioner,
What size circuit breaker for a 1 ton air conditioner unit?
About a tenth of a ton.
How are Branch circuit protected?
Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker

What size amp circuit breaker should be used for a home entertainment system?
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
What size circuit breaker should be used for dishwasher and disposal?
A 15 amp dedicated circuit breaker should be used for the dishwasher. The disposal can be wired to the general kitchen 15 amp circuit.
What size amp circuit breaker should be used for a geyser?
Depends on how many amps it pulls and the size of the wire in the circuit.
What size amp circuit breaker should be used for a pool light?
The pool light is usually on a 15 amp circuit. The breaker feeding this circuit must have a GFCI rating.
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
Number 10 thnn copper wire.
What size amp circuit breaker should be used for 110 outlet?
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
What size amp breaker for a 220V air conditioner?
a 2p 20 amp should work fine for a single 220 air conditioner,
What is the cable size for 7.5kw slit system air conditioner?
The wire is sized to the maximum overcurrent protection device (Max circuit breaker) ampacity. This is listed on the nameplate of the outdoor condensing unit. Size the wire to match the breaker.
Can a circuit breaker be tripped by using 20 amp sockets instead of 15 amp sockets?
A circuit breaker protects the wires that the devices are connected to. If the devices that are connected to the circuit are 20 amps the wire size should be #12 wire fed from a 20 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. If the devices that are connected to the circuit are15 amps the wire size should be #14 wire fed from a15 amp breaker. This breaker should not trip unless the circuit is overloaded or a fault occurs on the circuit. Putting 20 amp sockets on this 15 amp circuit will work but the circuit is limited to the amount of load that can be plugged in. You will not get the full capacity of the 20 socket because the breaker will trip at 15 amps.
