A breaker is sized by the conductor that is connected to it but also the load that is connected to the breaker. There are some cases such as motor loads where the breaker has to be 250% of the motors full nameplate amperage.
A #6 aluminium conductor with an insulation factor of 90 degrees C is rated for 55 amps.

What is the wire size for a 35 amp breaker to a ac unit?
You will need to use #8 wire.
What is the minimum wire size for a 30Amp breaker?
The minimum wire size for a 30Amp breaker is typically 10 AWG for copper wire and 8 AWG for aluminum wire, according to the National Electrical Code (NEC). This wire size is necessary to safely carry the amount of current without overheating.
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 do you need for 30 amps breaker at 220 volts?
For a 30-amp breaker at 220 volts, you typically need to use 10 AWG (American Wire Gauge) copper wire. If you're using aluminum wire, you should opt for 8 AWG. It's important to ensure that the wire insulation is rated for the appropriate temperature and application, and always adhere to local electrical codes and regulations.
What size wire and breaker you need for metal halide 400w bulb?
The size of wire and breaker sizing are based on the current of the circuit. To answer this question a voltage must be stated or look on the ballast for the amperage and add that to the question.
What is the recommended wire size for a 100 amp breaker?
The recommended wire size for a 100 amp breaker is typically 2-gauge copper wire or 1/0-gauge aluminum wire.
What is the recommended wire size for an 80 amp breaker?
The recommended wire size for an 80 amp breaker is typically 4 AWG (American Wire Gauge) for copper wire and 2 AWG for aluminum wire.
What is the recommended wire size for a 70 amp breaker?
The recommended wire size for a 70 amp breaker is typically 4 AWG (American Wire Gauge) for copper wire and 2 AWG for aluminum wire.
What size amp circuit breaker should be used in a kitchen with aluminum wire?
Don't use aluminum wire inside the house.
What size wire do I need for a 30 amp breaker?
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.

What size Aluminum wire is used for ground in breaker box?
For a 100 Amp breaker panel it would be 2 AWG. For 150 Amps it would require 2/0 (2 ought) aluminum wire.
Can aluminum 600v wire work a 40 amp breaker?
Wire size is rated by Amperes of current. You did not mention the wire size of the aluminum wire, so there is no way to answer your question. The voltage rating is more a rating of how good the insulation around the wire is.
What size wire do you need for a 50 amp breaker?
For a 50 amp breaker, you would typically need a 6-gauge wire.
What size wire do I need for a 50 amp breaker?
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
What size breaker for 12 gauge aluminum wire?
A #12 aluminium conductor with an insulation factor of 75 or 90 degrees C is rated at 15 amp. Therefore the largest size breaker to protect that wire will be a breaker rated at 15 amps.
What is the wire size for a 35 amp breaker to a ac unit?
You will need to use #8 wire.
