WitrynaI understand the rationale behind using 12/2 cable instead of 14/2 cable, but do not understand the rationale behind using the 20 amp circuit breaker instead of a 15 amp circuit breaker. Without understanding the rationale, I would assume it would be prudent to either: Replace the 20 amp circuit breaker with a 15 amp circuit breaker.
