50 amp rv shop receptacles

[fishtape]

Gents, I am bidding an RV repair facility. It has 20, 50 amp rv receptacles mostly in the building and a few on the exterior. These outlets should be protected by gfci circuit breakers being it is in a shop environment, at least I cant find anything in the code that states otherwise. 50 amp 2 pole breakers are not available for the 400 amp panel board. Am I wrong that these need gfci protection. If this were an rv park it would not have to be gfci protected but since its in a repair shop I believe it would. Any thoughts? Or am I missing something.

I forgot to mention the panel boards are rated 22k aic. Have a call in to the engineer.

i would use regular breakers in the panelboard and RV power outlet boxes with gfci breakers in them.

I was thinking something similar: a sub-panel with GFCI plug-in or bolt-on breakers, since so far that seems to be all that is available. Siemens and Eaton both have them rated 22kAIC, don't know if others do yet.

midwest U054C and special order have them install gfci breakers.

shouldnt the 6ga wire to the rv outlets take care of the fault current rating issue?

I spoke with the engineer and they said there are several options they are looking at including service entrance conductor sizing, installing separate panelboard and verifying the rating with Duke Energy.
May reach out to midwest and see if thats an option. I would prefer the "reset" be near the work area than on the other side of the building.

You just need 50A? Why not 30a as well? Or are they going to use dog bones?

I like the Siemens TL137us boxes for outdoor RV receptacle locations.
