This is determined by the size motor and the amount of amps the motor draws, be on the safe side and consult the owners manual or an Electrician.

The sizing of the breaker and feeder wire is based on the amperage of the compressor. Look on the name plate and find the amperage. The amperage on the nameplate then has to be multiplied by the motors full load amperage and that value is used for the wire size. Because the load is a motor the FLA is again multiplied by 250% to size the breaker. This takes into allowance the high starting current of a motor from 0 to 100% RPM.

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.
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.
What size in amperage circuit breaker should be used for a pool pump?
The sizing of the circuit breaker and hence the wire size to feed the pump are all dependant upon the amperage of the pump. This question can not be answered without that information.
What is the smallest size circuit breaker found in the normal home?
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
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 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 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 wire for 240 volt 1 phase compressor?
If you have to ask here, you shouldn't be trying to wire in a 20A compressor. You will require a special circuit for the voltage and current with an independent breaker. Check your local code for the wire size or talk to a qualified electrician.
What is the standard to select circuit breaker?
Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
How do you know if the AC breaker matches the AC unit starting demand load?
Read the literature for the ac condensing unit, or the tag on the outside of the unit. Minimum circuit ampacity= minimum breaker, wire and fuse size. Maximum circuit ampacity= the maximum size. Your circuit breaker, wire size and disconnect fuses should all be at or between those 2 numbers.
