Thanks...you guys bring up some very good points.
The owner wants to have both the 50 and 30 amp outlets
available at each space to accommodate any size RV that may
come in. I did think of building something for the outlets
to shield from the weather. I intend on sharing one 50 amp
outlet with the space next to it...and the same with the 30
amp. In the buildings its not an issue, plenty of places
to mount 4 and 11/16" junction boxes with raised covers.
Its only in the outside spaces thats a problem. The RV
loadcenters would really almost be a waste because there
would never be a demand for that much power. The owner is
going to install 6x6" posts at the rear of each space.
All power will be in PVC....I just need to come up with
something other than the RV boxes. I will mount either
a 200 or a 125 amp loadcenter near the center of the spaces.
This is a 5 acre storage facility and will have maybe 2 places where 8 RVs will be side by side.
I will talk to the local State inspector and get his input..
