I found an adapter to fo from my Camper 30amp, to a 3 prong twist lock, but I have a 4 prong heavy cord I'd like to be able to use, so I need a 30 amp to 4 prong, and a 4 prong to a 3 prong, to use it going to my Gen.
Any help would be appreciated
 
Youngest going to have to make the a cable or like @Infamous1 said convert the outlet.
That cord wouldn't be kosher to sell for a UL listed application
 
Neutral and ground will go together in the 3 prong end. For what you're doing they're the same thing.

Outlet is on Gen. I could make an adapter, but, 4 to 3, I am not sure how

I may not be understanding your question fully but if I am Be careful to understand how the RV is wired. Don't do what the previous poster said, you'll fry the shit out of something. This isn't changing a damn 4 and 3 prong 220V dryer line in your house. This is totally different. That RV 30A chord has 1 hot, 1 neutal and 1 ground. Your generator if you are using the 220V outlet is 2 120V hots out of phase, 1 neutral and 1 ground. Search dogbone adapters. These are commercially available but you need one from the generator to the 30A RV female if I understand your question. Nothing in the RV is actually 240V so don't run two hots to the RV if you have a 30A unit by connecting the ground and neutral and using the two hots like the previous post said!! In a 30A RV you have just a normal 120v plug (whih is what i read you have). So for the dogbone adapters it's simple going from 4 to 3 prongs to serve a 30A RV, they just leave one of the hots blank on the 4 prong end and connect the hot, neutral and ground to 3 prong end. The big 50A rv's are just using the 220V service as two 120V lines to serve two panels in the RV. When they are in a shitty state park with a 30A 120V service, that single 120V hot is jumped to both sides of the 4 prong RV plug and you power both panels with the same measly 30A line. You can't run everything you can with the normal 50A service which is two 50A 120V lines one for each panel. Probably too wordy. Just google dogbone but for gods sake don't run two hots to your 30A chord and connect the neutral and ground. You'll fuck it all too hell. Link and pic below on one of the dog bones going from 4 to 3.

Sorry if I misunderstood and wrote all that for nothing. This is a good starting link below.

Truth. And better said than what I could have.....been biting my tongue and hoping someone would chime in....
And those 30 amp plugs piggy backed off a 50 amp out of the same box, yeah a crappy one burnt up my 30 amp cord on my camper this July. Told the office and the owner even new he had a problem.....last time I stay at that dive in Brevard. Adventure Village in case anybody else wants to avoid.

@Ron clear this up professional like. I've had too much sauce to explain how electricity works

So warning a fella not to wire it with 2 hots a neutral/ground since some blurr the lines given how single phase works in a panel was a bad idea!
If it ends up anything like a welder or dryer plug: good by camper inverter is all I think we was agreeing on.
Many new gensets come rv ready. Some do not and that 4 prong twist lock provides 220 on two 120volt hot legs....
 
My apologies guys. I did not realize that rvs ran a special plug with only one hot. Seems silly to only have one circuit but I guess they have a reason. When he said 3 prong to 4 my mind said dryer plugs.

Don't do what I said in my first post, you'll f your stuff up :lol:
