Crouse-Hinds TP664 – Frequently Asked Questions

1) Which Crouse-Hinds TP switch box do I order for NM (Romex) cable versus armored or MC cable?
The cable type decides the part number. For non-metallic cable with clamps in each end, order TP662 (with 2-screw ears) or TP664 (bracket "S", set 5/8"). For armored and metal-clad (MCI) cable with clamps in each end, order TP668 (2-screw ears) or TP670 (bracket "S", set 5/8"). The clamps are built into the box ends, so you are choosing the clamp style, not adding connectors.
2) How many conductors can I legally put in a 14 cubic inch steel switch box?
Capacity is 14 cubic inches on this Crouse-Hinds 2-3/4 inch deep gangable box. Under NEC box fill rules that works out to seven 14 AWG conductors (2.00 cu in each) or six 12 AWG (2.25 cu in each) before you deduct for the device, clamps and grounds, which is why a single switch or receptacle with a two-cable feed-through is about the practical limit. The box is built to NEC/CEC standards.
3) Can I gang two of these Crouse-Hinds switch boxes together for a two-gang switch?
Yes. The box is gangable, so the sides come off and two or more boxes join to make a multi-gang assembly. Each box you add brings its own 14 cubic inches, so a two-gang assembly gives you 28. Note that once ganged, the removed side wall means the 1/2 inch side knockout on the joined face is no longer usable for entry.
4) What is the difference between the 2-screw ears version and the bracket "S", set 5/8 inch version?
Both mount the box, but differently. The ears versions (TP662 and TP668) have integrated ears you screw to a framing member or use to set the box flush in an existing opening. The bracket "S" versions (TP664 and TP670) carry a bracket set back 5/8 inch, which nails or screws to the face of the stud and automatically positions the box front 5/8 inch proud for 5/8 inch drywall or panel. If your wall finish is 5/8 inch, the bracket "S" box saves you eyeballing the setback.
5) Is this Crouse-Hinds steel box rated for hazardous or wet locations?
No. It is for ordinary, non-hazardous locations only. Do not use it in a classified area or in place of a weatherproof or explosionproof enclosure. For an exposed exterior or damp application, a cast box such as the Thomas and Betts Red-Dot 2IH3-2 RT box is the type to look at instead.
6) What should I use instead of the Crouse-Hinds TP662 switch box when I need more conductor space than 14 cubic inches?
The Crouse-Hinds 2-3/4 inch gangable steel switch box holds 14 cubic inches, which fits a single device in a standard stud bay. When the splice count outgrows that, step to a 4 inch square box such as the RACO 232MS welded box, which is 2-1/8 inches deep and rated 600V - a square box gives you a larger footprint for conductors and can be covered with a device ring to take the same switch or receptacle.
7) Can I run 1/2 inch EMT or flex to this switch box?
There is one 1/2 inch knockout in the bottom and one 1/2 inch in the side, so yes, 1/2 inch conduit connectors land in either. The end openings are 2-cable knockouts with the integral clamps, intended for cable rather than conduit. If every run on the job is conduit and you want more raceway entries than two, a box with multiple threaded hubs is a better match, such as the Thomas and Betts Red-Dot 2IH3-2, which carries three 3/4 inch hubs.
8) Should I use a gangable steel switch box or a non-metallic steel stud box for a metal stud partition?
A steel gangable box like this one needs a framing member or an opening to grip with its ears or bracket, and being steel it has to be bonded as part of the equipment grounding path. For light metal stud framing where you want a one-gang box that snaps to the stud and needs no bonding, the Cantex EZ20SB EZ Box non-metallic steel stud box is the alternative. Choose the steel box when you are running armored or MC cable, since the clamps on TP668 and TP670 are made for it.
9) Do I need separate cable clamps or connectors with these TP switch boxes?
No. All four versions come with clamps in each end, so NM cable on TP662 and TP664, or armored and MC cable on TP668 and TP670, terminates in the box itself. You still need to supply your own connector for anything entering through the 1/2 inch bottom or side knockout, and a device plus cover plate.
10) I need more volume than 14 cubic inches for a splice point. What else should I look at?
Ganging a second box doubles you to 28 cubic inches, but if you are making up a junction rather than mounting a device, a 4 inch square box is the usual move. The RACO 232MS STAB-iT welded 4 inch square box is 2-1/8 inches deep and rated 600V, and gives you a much larger wiring compartment with a plaster ring to suit your device.
