Crouse-Hinds TP294 – Frequently Asked Questions

1) How many conductors can I put in a Crouse-Hinds TP294 outlet box?
The TP294 gives you 21.5 cubic inches of interior volume, so your conductor count comes straight off NEC box fill math for the wire gauge you're running. At 2.25 cubic inches per 14 AWG conductor that's nine; at 2.5 per 12 AWG it's eight, before you subtract allowances for devices, clamps and grounds. Plan it as a 21.5 cu. in. box and deduct for whatever device goes in it.
2) When should I use a PVC box like the Cantex EZ Box instead of the Crouse-Hinds TP294 steel outlet box?
The Crouse-Hinds TP294 is a 4-inch diameter by 2-1/8-inch deep steel round outlet box with 21.5 cubic inches of interior volume, intended for ceiling and wall-mounted device or fixture connections and for junction points in conduit and raceway systems. The Cantex EZ Box is a PVC multi-gang residential outlet box, so it is the choice when the opening calls for a nonmetallic enclosure ganged for more than one wiring device in residential work. If the rough-in is a single round fixture or device point and a steel enclosure is preferred, the TP294 is the match; if you need multi-gang nonmetallic, the EZ Box is the different form factor.
3) Will a 4-inch round steel box fit a standard ceiling fixture canopy?
The 4-inch round profile is the common format for ceiling and wall fixture boxes, and the TP294 is that size: 4 inches in diameter, 2-1/8 inches deep. Most light fixture canopies and round device covers are built around the 4-inch round pattern, so the box lines up with standard fixture and device applications.
4) Is 2-1/8 inch deep enough to get a device and splices in without crowding?
At 2-1/8 inches the TP294 is a deep 4-inch round, which is what you want when a wiring device plus splices have to share the box. That depth is where the 21.5 cubic inch volume comes from. If you're only landing two cables and a ground, a shallower round box would do; for a device with pigtails and wirenuts, the extra depth is the reason to pick this one.
5) Steel outlet box or PVC: which should I use for this job?
The TP294 is steel, which is the choice for conduit and raceway junctions and anywhere the box takes jobsite abuse or needs to carry an equipment ground through metallic raceway. For residential nonmetallic cable work in walls, a PVC box like the Cantex EZ Series multi-gang residential outlet box is the usual alternative. Steel also matters if your installation is light industrial rather than residential.
6) Is the TP294 a multi-gang box?
No. The TP294 is a single round 4-inch box, not a gangable rectangular one. If you need two or more devices side by side, look at a multi-gang box such as the Cantex EZ Series PVC multi-gang residential outlet box instead. The TP294 suits one device or a fixture connection.
7) Is the Cantex EZ Box a direct replacement for a Crouse-Hinds TP294?
No. The TP294 is a round steel box measuring 4 inches in diameter by 2-1/8 inches deep with a 21.5 cubic inch volume, a single-opening format used for fixture and device connections. The Cantex EZ Box is a PVC multi-gang residential box, a different material and a different gang configuration, so it does not drop into a round 4-inch cut-in or carry the same 21.5 cubic inch fill figure you would plan conductor counts against. Treat them as separate product families rather than interchangeable parts.
8) What part number do I order for the Crouse-Hinds 4-inch 21.5 cubic inch steel round box?
Order Crouse-Hinds TP294. That's the manufacturer part number for the 4-inch diameter by 2-1/8-inch deep steel round outlet box with 21.5 cubic inch volume.
