30/ 15 adapters
Do they work as they say 45 amps
Forum Discussion
I've been in the same dilemma I'm adding a second ac to my 30 amp system. I am taking the second A/C wiring into a small breaker box and 20 amp breaker like this...breaker box
and a 10 or 12 gauge pigtail with a plug coming out of it. The 20 amp breaker is 8 bucks.
And I am using this at the trailer not at the power pole....adapter and then one of these....50 amp ext cord I,m shortening my 30 amp cord out of the trailer to 2ft and making an ext cord out of it in case I need a 30 amp while making room in my small electrical center. I am also adding an outlet off the other 20 amp breaker from my 5500 gen, its already wired. Additionally I am using two dometic b59530 high efficiancy a/c's that draw 9.9 amps each and put out close to 15k according to Dometic and they can run off a 15 amp breaker.
This way it looks like you are running a 50 amp service (in the case of CG's that don't allow 2 cords) you have the original breakers for the 30 amp and an additional 20 amp breaker just for the A/C. I don't see any danger here on 50 amps except to the 50 amp ext cord if it shorts, the rest of the trailer/rv is protected by the original and added breakers. If on shore power you plug in 30 amp trailer and 20 amp A/C, if on gen you plug in 30 amp to original plug and A/C on the 20 amp load center with it's own breaker........and there you have it.
