#12 AWG Copper. (The previous answer, "12/2 with ground", was incorrect. That answer specifies Romex. Not all homes are wired in Romex, and if they were, it would be acceptable to use any number of conductors inside the cable, including 12/2, 12/3, 12/4, and even the "new" 12/2/2.) If you receive free breakers with a "panel kit", and they are 20A breakers, keep in mind you cannot use them where a 15A breaker was previously. The wires on the 15A breakers is likely 14 AWG which can overheat and cause fire if installed on a 20A breaker. The 'weakest link' is supposed to be the breaker, not the wire. -------------- If you do not understand the work well enough to accomplish it yourself properly and safely, don't try it. Consult a professional electrician, as they are proficient enough to do it properly and safely.When working on electrical circuits and equipment, make sure to de-energize the circuit you will be working on. Then test the circuit with a definitive means to make sure it is off (multimeter with metal tipped leads, voltage tester with metal tipped leads, etc., not a non-contact tester, which is non-definitive.)

What is the minimum wire size for a 30Amp breaker?
Use only AWG # 10 copper.
What size wire for 28 amps?
Minimum size is 10 gauge with a 30 amp breaker. To be safe I would install an 8 gauge with a 40 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.
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.
Can you switch from 15amp to 20amp on a double pole breaker?
The minimum size wire a 20 amp breaker needs to be connected to is a #12 wire. The 15 is probably connected to a #14 right now which is only rated for 15 amps. Remember the breaker is sized to the wires ampacity not the load .
What is the minimum size wire allowed for a parallel run?
The minimum size wire that can be paralleled together stated in the electrical code book is a #3 copper conductor.
What is the minimum wire size for a 30Amp breaker?
Use only AWG # 10 copper.
What size wire for 28 amps?
Minimum size is 10 gauge with a 30 amp breaker. To be safe I would install an 8 gauge with a 40 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.
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.

What size breaker does it take to run a outdoor well?
Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.

What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
What size wire do you need to wire a 200 am breaker box?
6
What Size breaker for 6 gauge wire?
You need a 60 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.
