Yes, the 20 amp Circuit Breaker # PK54220PL and the 50 amp Circuit Breaker # PK54250PL can be used in place of your current circuit breakers. Circuit breakers are universal and can be used for a variety of setups as long as they are installed with the appropriate value so the specific circuit doesn't overload.
