∙ 2011-01-15 00:15:45The correct wire size for a 15 amp breaker is a #14 wire.
The minimum size wire to be fed from a 20 amp breaker is a #12 AWG.
Depends on what size wire was used in that circuit. AWG #10 wire requires the use of a 30 amp breaker AWG #12 wire requires the use of a 20 amp breaker AWG #14 wire requires the use of a 15 amp breaker Check the wire size in the circuit and you will know what size breaker to use. It is not going to be a 25 amp breaker.
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
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.
Depends on the size of the wire going to the A/C. If the wire is AWG #10 you cannot install a 40 amp breaker. If the wire is AWG #8 you can.
You need a 60 amp breaker.
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
