Is a 12 gauge wire on 20 amp breaker safe for a sub panel?

No, a 12 gauge wire is rated for 20 amps, which matches the breaker size. It is not recommended to use a wire that matches the breaker size as it can result in overheating and potentially cause a fire hazard. Consider using a thicker wire, such as 10 gauge, for the 20 amp breaker to ensure safety for the sub panel.


Can i use aluminum wire from service panel to hot tub sub panel?
