Thomas & Betts FDC3-TB – Frequently Asked Questions
1) What is the Thomas & Betts FDC3-TB box used for?
The FDC3-TB is a one-gang deep device box in the FD style, cast iron, with thru-feed hubs so conduit can run in one side and out the other rather than dead-ending at the box. It takes a single device (switch or receptacle) behind an FD cover, and the deep body gives extra wiring room compared with a shallow FS body.
2) What conduit size does the FDC3-TB take?
The hubs are 1 inch. Thru-feed means there are threaded hubs on opposite ends, so 1 inch rigid or IMC lands directly on the box without a separate connector.
3) Does the FDC3-TB come with a cover?
No. The FDC3-TB is the box body only, a one-gang deep iron device box. You order the FD cover separately to match the device you are installing, switch, duplex receptacle, GFCI, or blank.
4) Can I run conduit straight through this box instead of terminating at it?
Yes, that is what the thru-feed configuration is for. Hubs on both ends let a 1 inch run pass through the box while you tap a device off it, so you do not need a separate junction body further down the run.
5) Is a cast iron FD box the right choice over a die-cast aluminum one?
Iron is the heavier, more impact-resistant option and is the usual pick for industrial interiors, plant floors, and exposed conduit work where a box can get struck. The FDC3-TB is cast iron. Aluminum FD bodies are chosen instead where weight matters or where iron would corrode faster, such as some coastal or chemical exposures.
6) Will a standard switch or receptacle mount in the FDC3-TB?
Yes. It is a one-gang device box, so a single standard strap-mounted device fits, with the device screws landing in the box ears and the FD cover trimming it out.
7) What is the exact part number to order this Thomas & Betts box?
Thomas & Betts FDC3-TB. The C3 designates the thru-feed (two opposing hub) configuration in 1 inch trade size, deep body.
