• Since your circuit breaker does not have different color terminals you will want to look closely on the Pollak 20 Amp Circuit Breaker, part # PK54520, and the Pollak 40 Amp Circuit Breaker, part # PK54540 for markings. The poles will be marked with BAT right next to the battery terminal and AUX right next to the auxiliary terminal. A circuit breaker should have one of the poles marked as a battery terminal.

• Can 2 Circuit Breakers Share the Same 12 Volt Power Wire
  
• The problem you may run into when trying to power 2 circuit breakers from the same hot lead is that if there is a back feed problem on one circuit breaker it can affect the other one and cause some problems. It would be best to use a separate hot lead for each circuit breaker.
