Crouse-Hinds 451DC – Frequently Asked Questions

1) Is the 451DC set screw connector OK for a damp or wet location?
Set screw EMT fittings like the 451DC are for dry indoor use. The set screw body is a mechanical grip, not a sealed joint, so if the run is outdoors, in a wet location, or subject to washdown, use a raintight compression connector instead. The die-cast zinc body does give corrosion resistance for normal jobsite and interior commercial conditions.
2) Do I need to thread the conduit to use a set screw EMT connector?
No threading, and no threading tools. The 451DC clamps the EMT with a set screw, so you cut the tube, ream it, slide it in, and tighten the screw. That is why set screw fittings are the fast choice for rough-in work compared with threaded or compression terminations.
3) Does the 451DC connector carry the equipment ground through the EMT, or do I need a separate bonding wire?
The metal-to-metal path matters here. The 451DC is a die-cast zinc body intended to provide a solid mechanical and grounding path connection between the EMT and the enclosure, which is how EMT raceway is normally used as the equipment grounding conductor. You still need to tighten the set screw and the locknut properly, and if your project spec calls for a separate bonding jumper or a green insulated conductor in the raceway, pull it.
4) What is the difference between an insulated and a non-insulated EMT connector, and which is the 451DC?
The 451DC is non-insulated, meaning there is no plastic throat bushing in the conduit end. That is the standard choice for typical EMT terminations. If the conductors are larger or the spec calls for an insulated throat to protect the wire during the pull, order an insulated-throat version of the same trade size instead.
5) Is the 451DC a straight connector or an offset fitting?
Straight, in-line only. The 451DC makes a direct EMT-to-enclosure termination with no bend in the fitting, so it suits a conduit stub landing square on a panel or box knockout. If you need to step the raceway over to meet a knockout that is not in line, use an offset connector rather than this one.
6) Can I buy the Crouse-Hinds 451DC with a different finish or material?
The 451DC comes one way: natural die-cast zinc, no coating or plating variation, sold under manufacturer part number 451DC. For property managers and MRO buyers standardizing a stockroom, that keeps the 3/4 inch EMT set screw connector a single line item with no finish or option codes to pick.
7) Is anything else needed to land 3/4 inch EMT into a panel with this connector?
The connector handles the conduit side and the knockout side of the joint. On the job you will also want a reamer or file to debur the cut EMT so the wire pull is not damaged, and a nut driver or flathead sized to the set screw. If the knockout is larger than 3/4 inch, add a reducing washer set; if it is smaller, a step bit or knockout punch opens it up.
