Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
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.
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.
25 amp breaker
A 100-A sub-panel would be fed from a 100-A breaker.
No, you should not replace a 15 amp breaker with a 20 amp breaker without consulting a licensed electrician. The breaker size should match the wire size to prevent overheating and potential fire hazards.
Depends on the wire size you are using. If the generator breaker is a 30 amp then install a 30 amp breaker.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.
The recommended wire size for a 20 amp breaker is typically 12-gauge wire.
The appropriate wire size for a 25 amp breaker is typically 10 gauge wire.
The appropriate wire size for a 30 amp breaker is typically 10 gauge wire.
The recommended wire size for a 25 amp breaker is typically 10 gauge wire.
The recommended wire size for a 30 amp breaker is typically 10 gauge wire.
The recommended wire size for a 50 amp breaker is typically 6-gauge wire.
The recommended wire size for a 60 amp breaker is typically 6-gauge wire.
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.
For a 240-volt circuit that requires a 50 amp breaker, the appropriate size of the breaker needed is 50 amps.
