Thomas & Betts FD3-TB – Frequently Asked Questions
1) What does the "dead end" mean on the Thomas & Betts FD3-TB box?
Dead end means the box is closed at one end, so conduit only enters from the other hub. The FD3-TB is a 1-gang deep device box in a dead-end configuration, which is what you use at the end of a conduit run, a final device drop, or a corner where you have nothing continuing through. If the run has to continue past the box, you need a through-feed (feed-through) FD body instead.
2) Does the FD3-TB box come with a cover?
No. The FD3-TB is the box body only, a 1-gang deep device box with a 1 inch dead-end hub. You order the cover separately, and the cover is what determines the opening: blank, single receptacle, duplex, GFCI, or toggle switch. Order it at the same time so the box isn't sitting open on the wall.
3) Is the Thomas & Betts FD3-TB suitable for outdoor or wet locations?
FD boxes like the FD3-TB are cast iron bodies with threaded hubs, the standard choice for exposed exterior and damp industrial work where a stamped steel box won't hold up. To get a weatherproof assembly you still have to add the cover and gasket that match the device you're installing, since the box ships as a body only.
4) What is the difference between an FS and an FD box like the FD3-TB?
Depth. FD is the deep body, FS is the shallow one, and both take the same covers and the same 1-gang device. The FD3-TB is the deep version, which gives you more room behind the device for conductor volume, a GFCI, or a bulky dimmer. If you're tight to a wall or column and only landing a switch, the shallow FS body is the easier fit.
5) Will a standard duplex receptacle mount in the FD3-TB?
Yes, it's a 1-gang box, so one standard device (duplex receptacle, switch, or GFCI) mounts in it using the matching 1-gang FD cover. It will not take two devices side by side; for that you need a 2-gang FD body.
6) What is the exact part number to order for the Thomas & Betts 1 inch dead-end deep FD box?
Order Thomas & Betts FD3-TB. The 3 in the number is the 1 inch hub size and it's the dead-end, 1-gang deep configuration in cast iron.
