Electrical splitter. Little help please

We went to teo different parks last night and both only had 20 amp out let's. I have 3 air conditioners and can run one if I have 30 amps. My coach has a 50 abp cord and when I have 30 amps I use a splitter I can make it work. My question is do they make a 30amp splitter and if so could I take two 15 or 20 amp connections and rum them into my splitter and then into one side of my 50 amp splitter to get the 30 amps I need to run my one air conditioner?? I hope I didn't make this two confusing. I am just trying to find a way to get one air conditioner to run off two 15-20 amp outlets. Thanks in advance for any assistance.

Safe travels

Generally speaking the anwser is no--15/20 amps plugs are about as low as it goes. There are adapters [pigtails or "splitters] that convert 50 to 30 and 30 to 15/20, but none that convert/combine two 15/20s. I have seen an adapter advertised that converts one 30 amp and one 15/20 to a 50 amp but am not sure how those work as you can have problems with your surge protector with multi-ground sources?????

Again, 15/20 is the bare minimum but if you turn off almost everything else [bat charger, hot water to propane, etc, etc, you may be able to get by with one A/C unit.

Confucious say: Those with 50a coaches with 3 ACs that go to 20amp only campgrounds during very hot summer get/had brains cooked.

If brains not cooked to bad, bite bullet run generator or move.

As Old Scout said, if you turn ALL 120V off in the coach except 1 AC, you may get it to work. Not something I would consider unless it was an emergency where I couldn't move.

You can use two 20A outlets but they should go to separate legs of your 50A cord unless you are absolutely sure they are not out of phase with each other. If they are out of phase you will have 240v between them and a major short if you combine on one leg. Big fireworks for a short time!

You should be able to run one a/c on a single 20A circuit. Your problem is that you have two a/c's on one leg, so that leg will always trip a 20A breaker, even if everything else is turned off. Flip the circuit breaker off on one of the a/c's on L1 and it might work. First put everything else on propane, though. However, if you have residential fridge it still may overload.

You can use a "cheater" box or Y cord to utilize two 20A outlets as two seprate legs on your 50A cord. That works as long as neither outlet is a GFCI.

The kind of device you describe is **NOT** GFCI friendly.. Though an old park may have grandfathered outlets that are NOT GFCI... Odds are they are GFCI and such a device will calse the click of darkness to ensue.
Home is where I park it!

Thanks for all the information. We are in a park that I was able to use two 30 amp plugins into my 50 amp splitter. I can run two air conditioners (using low fan setting).

Safe travels everyone
