50-30 adaptor

NO!!! Do not even think of doing that.

If you short the two legs together, you make a short circuit when plugging into a normal 50A outlet. The two legs have opposite phasing, so they have 240V RMS between them.

It sounds to me as though you're backfeeding your panel from the "outlet" for the generator. This is a dangerous and (in most cases, at least) illegal way of doing things. You need some manner of transfer switch that does not let you connect the generator and the shore power cord at the same time. As it's wired now, if I'm understanding your post correctly, you have 120V exposed at the 50A plug when running off the generator (at the least), and if you connect to shore power with the generator plugged in you stand a very good chance of destroying the generator (and hopefully not doing anything worse). If you were to plug in a traditional, non-inverter generator, you could very well destroy it in extremely violent fashion, with heavy parts of the generator's alternator flying free.

Please, please, pretty please get help from someone who's qualified to do electrical work.

Hi.
After reading your replies I can see that I am back feeding my
My panel from the generator and yes the prongs would be Hot. I really
Never noticed the exposed prongs as the whole 30 amp cord was attached attached
And coiled up on the ground.
But I guess if I would have touched the ends I would have found out in a hurry.
Sounds like I need to use the normal 50-30 amp adapter and the shore power cord and just run it from
The back of the trailer up to the generator, or get a transfer switch.
I was trying to be able use the generator up front without running the main power
Cord from the back of the trailer to the front.
Thanks Guys
