50 Amp Shore Line Readings

50 Amp Connection.002 by Fantinesvoice.com, on Flickr

It would appear that what goes in to the Airstream from a 50 Amp shore line is 120v on each side and when read across the two hot poles, 240v. This is correct as the connection was running my moho for three years, reads as correct with my line monitors, and has given no problem. I would therefore have to conclude my 50 Amp to 30 Amp configuration as shown in the earlier photo, is indeed correct.

50-amp adaptors

These adaptors cover all the bases for my 50-amp wired Airstream. I stay with the pudgy 50-amp cord to reduce clutter, overloads and line loss. And a surge protector heads it all up, which is a whole other topic.

Here's a nice review of the setup. Easy to understand the 50 amp with its two legs. Also if you look at the 2014 AS owners manuals you will see usually 8 sub breakers, 4 on each side of the two 50 amp CB's in the middle. Easy to understand what is on each side.

Test of new cord

So, after checking all the info I could, and very helpful was the post by ghaynes755, I hooked up the 30 Amp male plug into my 4000w generator, the the 50 Amp end into the Airstream receptacle, and obtained 14.4 v, and the a/c ran well, switching between front and rear to do a complete test.

As noted in the excellent article "FTLS - Electrical Distribution", when on 30 Amp it is running the entire 30 Amp over both legs of the electrical circuit.

So, the test went well, the generator running bout two hours with no problems.

I use a similar set up but with two 2000 Honda's running in parallel. As you noted runs one A/C at a time, which is fine. If I just want to hit the batteries I run only one to charge them up if the solar is not doing the job.
