Shore power plug

[Elodie]

Hello,

I'm having issues locating the right kind of converter to plug my trailer into a house outlet. The trailer plug has two straight prongs (in an L) at the top and a round prong at the bottom (see picture) the trailer adapter plug I ordered off of eBay however has the same two straight prongs (in an L) at the top but a half round prong on the bottom. Does anyone know where I can find a 15 amp male to 30 amp female adapter for the correct prongs? Thanks for the help!

The one in your photo appears to be correct one to go from 30 amp RV to 20 amp household. Those adapters are available off the rack at most Wal-Marts.

The only thing wrong with the adapter I have is the half round prong hole ( the trailer plug is a full round prong) I can't insert the round prong in the half round hole, it just won't go in

Cant you just buy the right plug and swap em out? I made a 50 amp 30' cord that way.

If that lower photo is not for a 30 amp RV, I don't know what it could be for. There is no other similar outlet that I am aware of.

Both of my adapters look just like yours. You have the correct adapter. It looks like the round prong on your RV plug might be a little bent out of line.

Ok, let me ask anyway. Did you check CampingWorld? Under "electrical converters?

Brian.

DO NOT use the right hand adapter, IF your going to run the AC.

It will melt and possibly catch on fire, as they ave many times in the past.

I have run into this problem on the older AS which use the round ground plug pin. The newer standard is the D shaped ground pin. You may have to do some looking to find an adaptor which will take the round pin, and I can't suggest a brand, but there are some out there.

You also can replace the plug on your power cord with a newer one which has the D shaped ground. Since your plug is 35 + years old, might not be a bad idea anyway.

Andy, I never use the air conditioner or heat pump with any 30 amp to 20 amp adapter. What I was pointing out is that the OP has the correct adapter already for what he is trying to do.

Thanks for the replies, I have checked camping world but no luck...
Any tips on or links to threads dealing with replacing the plug?
Thanks again

The round and D-shaped terminals are supposed to be interchangeable. You could try using a little grease, or try cleaning up the ground pin with some emery cloth. I use the electrical grease sold in home centers for use with aluminum wiring but ordinary chassis grease or vaseline will work. You might have to use a little force and rock the plug in a circular motion while pushing it in. Also the connectors tend to shrink in cold weather (below 30 degrees) and become difficult to connect, and while I see you say you're in the bay area that could be a factor if you were trying this somewhere cold. Finally it may just be that the adapter you got was poorly made -- trying another style or brand might help.

Replacement plugs are readily available and are not difficult to install for someone who has electrical experience. I don't suggest trying it without supervision if you haven't replaced plugs on things like extension cords or power tools before. Here is one source:
