Can you put 12 wire on a 25 amp breaker?
In respect to this, what wire do I use for a 25 amp breaker?
This application requires a 25 amp circuit breaker. Wire size is a very important part in sizing a circuit. For circuit breakers up to 15 amps, use 14 gauge wire or larger. For a 20 amp breaker, use 12 gauge wire or larger.
Additionally, can you put a 30 amp breaker on 12 gauge wire? A 30-amp breaker does not operate safely with a 12-gauge wire. The minimum wire size that is allowable for use with a 30-amp breaker is 10 gauge. A smaller gauge of wire indicates a larger diameter and the ability to carry more current safely. Twelve-gauge wire is acceptable with 20-amp or smaller circuit breakers.
Beside above, can I replace a 20 amp breaker with a 25 amp breaker?
If it is 20 amps or less, the #12 wire is fine. Then check the Maximum Overcurrent Protection (MOCP) or Max Fuse Size. If it says 25 amps or higher you can change the breaker to 25 amps.
What amperage can 12 gauge wire handle?
