What is a "standpipe"

[ryan_618]

406.8(D) Protection for Floor Receptacles. Standpipes of floor receptacles shall allow floor-cleaning equipment to be operated without damage to receptacles.

Any ideas as to what a standpipe is?

Not absolutely sure, but I believe it's the part of the box, in-floor duct sytem, housing, etc. that provides the cavity in which the receptacle is mounted. An example would be a Carlon round floor box...

...where the top part of the box is the standpipe and is cut to height after the floor is poured.

I think I'll make a proposal to the 2011 to elimate the word "standpipe" and replace it with "assembly". That way the box, cover and device would be included.

Smart$: I think you are probably right on that. Thanks.

I recall a screw in pipe that attaches to the threaded floor box cover. IE standpipe.

There is (was, rather) an old brass floor receptacle manufactured by Arrow-Hart that screwed into an 1-1/4" RMC coupling. Knowing that, I would guess that the standpipe would be the section of RMC leading up to the coupling that floor receptacle was assembled into.

LOL!

Normally, I think of standpipe as the vertical fire-department pipe I see in stairwells of buildings, where they can pipe water in at ground level and access it with hoses on whichever floor they need them. Sort of like a permanent temporary extension cord, with a plug at ground level and a receptacle on every floor.

In this case, I envision something like this:

Hi Ryan, I believe Roger has a picture of a floor mounted receptacle on a 'standpipe'.
