Rv Charging pedestal location

[Npstewart]

Hi again everyone, I posted a topic a while back when I started design for this covered RV storage, just finishing the design up now.

The architect for this project is telling me this building should not have to comply with section 551 of the NEC 2008. My question though is, given that it does not have to comply with the section (assuming it wont have to), he wants to put the charging pedestals right next to each other. They are supposed to go on the drivers side and within a certain amount of distance from the from driver side. However, he wants to put them RIGHT next to each other so effectively, if they are next to each other, one pedestal will be on the passenger side, and the other will be on the drivers side for the other bay. Obviously this will create a problem with cord lengths. I would hate for someone to pull in, and not have a long enough cord to charge. Does anyone know the maximum allowable distance of the cord (without taking into consideration of VD).



Thanks in advance

Does your storage area have pull through parking (i.e. a door at each end), or do you pull in and then have to back out? If pull through, then either side could be the drivers side.

Most RV's have fairly long cords (15' or more). If you survey a few, I think you'll find most have their electrical cords in the middle to 3/4 of the way to the rear. Most are 8' wide. So if you can get 15' of cord, you should be able to plug in assuming the pedestal is very near the rear wheels.

Finally, what are you expecting people to do in this RV storage place -- just keep the battery charged and the lights on, or run a full motorhome with dual air conditioners, electric hot water, and a microwave? If you're just trying to keep it charged, most RVer's have an adapter device to adapt their large cord to a 5-15P type. Most also carry a normal 120V extension cord so I wouldn't worry about distance (or keep a few #12 25' cords around).

What size receptacles are you installing (120V 20A, 120V 30A, or 120/240 50A)?

Thanks for replying.
This particular building has 3 walls, effectively its a lean to type of building. 8" CMU block on 3 sides, and a metal roof.


Im installing a pedestal that is equipped with (1) 30A/120V GFI receptacle, and (1) 20A GFI receptacle. total load on each pedestal is 3600VA per NEC article 551. The entire western electric assembly is one piece, and comes with a meter on the bottom, the whole thing is protected with a 30A breaker. So are you saying the rv's typically charge from the rear and not the front?

Basically, people are using this just to drop their RVs off. They are not permitted to sleep or stay in them. We have strict city codes that dont allow you to keep an RV in your driveway for about more then a 1/2 hour or so. Its basically a storage unit for RVs, and I guess they charge up prior to leaving.

thanks in advance/.
