Has anyone used the 15+30=45amp adaptor? How does it work and will it work with a 15amp GFI outlet ?

Abrnth3 said:Redandsilver, I am talking about a connector that hooks a 30 amp and a 15 amp receptacle and allows you to use 45 amps in your trailer.
There is no way to combine the 30A and 15A to supply 45A through a single system..
Gary RVer Emeritus said:I should also point out that, as a practical matter, putting a 30A and a 15A in parallel rarely yields a full 45A capability if they feed a single hot wire. Theoretically each source can deliver its rated amount, but in practice the 15A breaker will trip well before the 30A reaches its max. That's because both sources try to respond as the loads suck power and odds are the 15A side will overload and trip before the 30A side picks up the load. This often happens when a large load is added, but small loads added incrementally will often let a higher total be reached. A combined 30A+15A to one load wire might deliver only 35-40A. It's even possible that the 15A breaker will trip as soon as the total load exceeds 15A, so the net available might be as little as 30A. There are several real-world variables involved, so it's hard to generalize.
This isn't an issue when they feed a 4-wire plug like the RV 50A, The two hots remain separate and the loads are isolated to one or the other.

It states that it won't work on a 15 amp GFCI receptacle. I think one would have to do some funky math to get 45 amps out of it as implied. No way will it provide 45 amps like one could assume. They make it sound like your going to be able to get 10800 watts of power but you won't. Personally, I wouldn't waste my money.
