NEC 210.52 - sliding exterior walls

[leboot]

Hi all,

We're working on a high end residential apartment unit where the exterior walls are all sliding glass doors/panels. These sliding walls can either slide into a pocket or they can slide into the next room and the wall in the next room can slide into the first room (if that makes any sense). The size of these doors/panels is such that the distance between any wall mounted receptacles we have is greater than 12 feet.

NEC 210.52(A)(2)(2) - describes wall space as "the space occupied by fixed panels in exterior walls, excluding sliding panels."

I think we should provide floor receptacles so that no point measured along the exterior wall is more than 6 feet from a receptacle, but we're pretty sure the owner is going to come back and ask what is the minimum that is required.

So, my question is this: are all those sliding wall panels excluded from the definition of a wall space?

(We do have some columns here and there to mount receptacles, so they are some, just not a lot.)

Thanks for your input!

Are the pockets able to slide as well

In the couple locations where there are pockets, the pockets are in corridor space - not in the apartment.

In the one location, there are three panels of wall and there are three tracks. Each wall panel can slide along the entire length of wall.

From the definition, the answer is clearly yes.

I agree, even if it's 50' long or longer, no receptacle(s) required.
