Crouse-Hinds TP403RED – Frequently Asked Questions

1) Does the Crouse-Hinds TP403RED box have built-in cable clamps for NM/Romex?
No clamps. This box is configured for conduit entry only, so it is meant for EMT, rigid, or flex terminated with a connector at the knockout. If you are pulling NM cable, you need a box with integral clamps or you must add a listed cable connector at each entry. That is the single most common reason this box is the wrong pick for a residential rewire.
2) Can a Crouse-Hinds red 4 inch square steel box be used in a hazardous or classified area?
No. The box is rated for ordinary, non-hazardous locations. A Class I, Division 1 or 2 area, a paint spray booth, a grain handling area, or any classified space needs an explosionproof cast enclosure with threaded hubs instead. Using an ordinary location sheet steel box in a classified area is a code violation and will fail inspection.
3) Will a standard 4 inch square cover or mud ring fit the Crouse-Hinds TP413RED?
Yes. It is a 4 inch square box measuring 4 in by 4 in, which is the standard 4 square footprint, so ordinary 4 inch square flat covers, single and two gang device rings, and raised plaster rings land on the same corner screw pattern. Match the ring depth to your finished wall thickness, not to the box.
4) How do I choose between the 30.3 and 50.0 cubic inch Crouse-Hinds 4 inch square boxes?
Run the box fill first, then pick. Both share the same 4 in by 4 in footprint and take the same covers, so the only thing changing is internal volume: 30.3 cubic inches on the TP403RED, 50.0 on the TP413RED. The deeper 50.0 box is the one to order when several conduits land in the same box, when you are landing pigtails and grounds for multiple circuits, or when a device with a deep body has to sit in it. Since the openings are identical, the deeper box costs you nothing in wall prep.
5) Does the Crouse-Hinds red 4 square box meet code for a commercial electrical inspection?
It is built to NEC/CEC standards for ordinary, non-hazardous locations, so it is acceptable for general commercial and institutional wiring in unclassified spaces. Where it will not carry you is a classified area or a wet or hazardous location, which call for a different enclosure type entirely.
6) Is a welded steel outlet box better than a drawn one for a commercial job?
Welded construction means the box body is joined at the corners rather than formed from a single drawn shell. For a contractor the practical difference is that a welded box holds its shape when it is strapped hard to steel stud or hung off conduit carrying a heavy device, and the seams stay closed. This one is welded steel and is specified for commercial, industrial, and institutional work as well as residential.
