ARTICLE 370 -- Outlet, Device, Pull and Junction Boxes, Conduit Bodies and Fittings
370-1. Scope
Cast, sheet metal, nonmetallic, and other boxes such as FS, FD, and larger boxes are not classified as conduit bodies.

What are FS and FD boxes? How are they different than 4-square or device boxes? And how did they get the name FS and FD?

Here is a FS box.


The S means shallow. The D means deap. I belive the F stands for ferrous.

I still get a kick out of the fact that "ferrous" boxes are available in aluminum.
The third letter will designate the # and location of hubs in the same way as a condulet, ie. an FSC will have 2 hubs on opposite ends, etc.

Ok, then I'll go with FST referring to "ferrous shallow" T, like a condulet with end hubs and a side hub, not necessarily ferrous, and they appear to be meant for weather exposed and hard useage locations.
Does that sound right?
Thanks, C

Cindy, I'm looking at an O-Z/Gedney catalog and it shows three basic single gang shallow box configurations: FSS, FSCT, FSX. The FSCT would serve for your "FST", it has a hub at both ends and at one side. I don't see a box with a rear hub, like in a TB condulet, nor a box that would look like an LB or LR.

Oops, found more: FS--one end hub; FSC--two opposite end hubs; FSL and FSR--like LL and LR condulets. Also there is a FSA --no hubs; and an FSCC--two hubs on one end, one at the other end.

Yes, the one Cindy describes is actually an FSCT, an FST comes in one end, and out both sides. Maybe I oversimplified it.

We use them for any severe duty industrial application....grain elevators, ethanol plants, etc.

short of explosion proof enclosures then, would you say these fs/fd boxes are the best choice for weather and hard useage? i haven't tried to break one vs. trying to break a heavy plastic box but they do look and feel a bit like pot metal
