New converter installation-what breaker do i need

[HoosierMomma]

I am working on replacing my converter in my 2002 Cheyenne Coleman pop up. I am removing a centurion 3000 and putting in a progressive dynamics PD4100 series power control center. My previous converter has a single breaker with a 20amp and 15 amp combo. So when i bought circuit breakers for the new one i got single 20amp, and two single 15 amp breakers to fit it. Now i am questioning if i should be putting a 30amp breaker in. It would be the one i am booking g the Shore Power into.

The 30 amp breaker is the main breaker. It is wired backwards to that it feeds the other breakers. You need 20 for your a/c and 15s for the other circuits. Usually the 12 volt side is fed a breaker also.

Thank you for the response, but i don’t understand what you are saying. The first breaker is a 20amp(button broke during shipping) it has the Shore Power plug wired in, per diagram instructions. But i am wondering if it should be a 30amp breaker.

Depends on the feeder gauge wire, but yes, you’d typically expect a 30a mains from the power inlet. You’d expect 10awg for a 30a feed.

Its also possible someone replaced it already and used a 20a/15a split as thats what was handy.

These do come in a variety of combo flavors, but price and availability may limit the decision to purchase.

I would think a 30amp breaker with the wire from the cord to the breaker screw would protect and act as a main shut off to everything else. It looks like you only have room for two breaker spots left. You will need a 20 for the AC and a double 15 for everything else

The breakers should be available at any big box store (Home Depot,etc)

Your plug end will dictate your main breaker. Whatever that is, is your main breaker. 🏕
