Crouse-Hinds TP440 – Frequently Asked Questions

1) Do I need separate cable connectors for MC cable with this Crouse-Hinds 4 inch square box?
No. The box comes with AC/MC clamps built in, so armored and metal-clad cable lands directly in the box with strain relief, no separate connector needed. There are 4 cable knockouts for those entries. If you are pulling EMT instead, you would want a box with conduit knockouts and separate fittings.
2) Is this Crouse-Hinds box rated for a hazardous or wet location?
No. It is rated for ordinary, non-hazardous locations only. For a Class I or II hazardous area, or an outdoor wet location, you need a box built for that duty. A Thomas and Betts Red-Dot 2IH3-2 two-gang box with three 3/4 inch hubs is the kind of threaded-hub box used where a knockout-and-clamp steel box is not appropriate.
3) Can I bring a 1/2 inch conduit or connector into the bottom of this 4 square box?
Yes, there is one 1/2 inch knockout in the bottom of the box, in addition to the 4 cable knockouts for AC/MC entries. That single bottom opening is what you have for a through-the-back or bottom-fed run, so plan your entries around it.
4) Does this 4 inch square box meet code for Canadian jobs as well as US?
The box is built to NEC and CEC standards, so it can be specified on both sides of the border for ordinary-location work. That matters to procurement teams standardizing a single box across US and Canadian properties.
5) Will a standard 4 square cover or mud ring fit the Crouse-Hinds TP431?
The box is a nominal 4 inch square, 4 in by 4 in with a 2-1/8 in depth, which is the standard 4-square footprint that flat covers, single-gang and two-gang plaster rings are made for. Covers and rings are ordered separately, so add the ring depth you need for your wall finish.
6) If my wiring method is conduit rather than MC cable, is the Crouse-Hinds 30.3 cubic inch box still the right choice?
The Crouse-Hinds 4 inch square box is configured for armored and metal-clad cable with AC/MC clamps, so it suits MC and AC runs. For threaded conduit terminations, a hub box such as the Thomas and Betts Red-Dot 2IH3-2, which provides three 3/4 inch hubs, gives you a direct threaded connection without needing separate connectors at knockouts. For a conduit job that still needs a standard 4 inch square footprint and 2-1/8 inch depth, the RACO 232MS welded 4 inch square box is the same box form in RACO's STAB-iT series.
7) Is a welded steel box better than a drawn box for commercial work?
Welded construction means the box sides and bottom are joined at the corners rather than formed from one piece, and the joints are what keep the box square under a nail gun and a drywall crew. This one is welded steel throughout. If you are standardizing a job on welded 4-squares, the RACO 232MS STAB-iT Series 4 inch square welded box is a 2-1/8 inch deep equivalent from another brand.
