For your convenience, we offer twin breakers compatible with Progressive Dynamics AC Panels and many other RV breaker panels. Although regular 1" wide breakers fit the AC panels, we prefer these twin breakers because they allow for more branch circuits on the panel. 

Twin breakers are simply 2 breakers in the space of one and operate exactly as a regular breaker. You'll see them in various combinations, like 20A/15A or 30A/20A. The designations simply describe how the breakers are paired. A 20A/15A twin contains one 20A breaker and one 15A breaker in the space of one regular size breaker.

NOTE: There are many ways to wire a recreational vehicle. Always consult with local codes to determine what size breakers you need for your wiring, load and load center.
