Thomas & Betts TB844 – Frequently Asked Questions

1) What is the difference between a chase nipple and a regular conduit nipple or coupling?
A chase nipple like the Thomas and Betts 844 joins two boxes, conduit bodies, or enclosures back-to-back without a locknut between them, so the joint stays as short as possible. A standard threaded nipple plus locknut needs more clearance between the two housings. If you have room and want to run conduit between enclosures, use a nipple or coupling; if the enclosures sit against each other and space is tight, the chase nipple is the fitting.
2) Will the Thomas and Betts 844 chase nipple thread into a 1 inch hub on a junction box?
Yes. The 844 is a 1 inch trade size fitting threaded on both ends, sized for standard 1 inch conduit bodies, boxes, and enclosures. It threads directly into the mating 1 inch opening on each side. For other trade sizes you need the corresponding size chase nipple, not this one.
3) Do I need a locknut with a Thomas and Betts 844 chase nipple?
No locknut is needed between the two connected enclosures. The 844 threads into both housings directly, which is the whole point of the chase nipple design and why it keeps the joint footprint small.
4) How many chase nipples come in a box of the 844?
The 844 ships 100 pieces per pack, which is how electrical contractors and MRO stockrooms usually buy a common 1 inch fitting. If you need a handful for one panel, you are still ordering the 100 count carton.
5) Does "non-insulated" mean I need a bushing with the 844 chase nipple?
The 844 has no insulated throat, so there is no plastic liner protecting conductors at the opening. For enclosure-to-enclosure connections it is used as-is. If your install calls for insulated throat protection on the conductors passing through, specify an insulated chase nipple instead of the 844.
6) Can I use a chase nipple to couple two panelboards mounted side by side?
That is a standard use for the 844. It is specified for back-to-back conduit body and enclosure connections, panelboard and junction box wiring, and tight-space work on commercial and industrial conduit systems, in both renovation and new construction. Both openings must be 1 inch trade size for this fitting.
