B-LINE 66-4XSFN6 – Frequently Asked Questions

1) Will the B-Line 66-4XSFN6 nipple section fit a 6 x 6 wireway run?
Yes. The Eaton B-Line 66-4XSFN6 is sized for 6 inch by 6 inch wireway, measuring 6 in height by 6 in width, with a 5.938 in length. It is the short connecting section used to join two wireway bodies or to tie a wireway into an enclosure, not a full-length trough.
2) Is this stainless wireway nipple rated for washdown or outdoor use?
The 66-4XSFN6 nipple section is NEMA 4X and UL Listed, so it suits washdown, corrosive, and wet locations where the rest of the wireway run carries the same rating. The stainless steel body with brushed finish is what earns the 4X corrosion rating; painted carbon steel 4 or 12 wireway will not hold that rating in the same environment.
3) What does a feed through nipple section do in a wireway layout?
Feed through means conductors pass straight through it. The 66-4XSFN6 is the short 5.938 in piece you put between two 6 x 6 wireway sections, or between a wireway and an enclosure, so the wire run is continuous and the whole path stays sealed to the NEMA 4X rating. It is not a pull box, tee, or elbow, so it does not change direction of the run.
4) Can I use this on a painted steel wireway run instead of stainless?
Mechanically the 66-4XSFN6 is built for 6 x 6 wireway, but it is a stainless steel 4X part. Mixing it into a painted steel NEMA 1 or 3R run gives you no benefit and puts dissimilar metals in contact at the joint. Use it where the rest of the run is stainless 4X, which is how the rating is maintained end to end.
5) What exact part number should I order for a 6x6 stainless 4X feed through nipple from Eaton B-Line?
Order Eaton B-Line part number 66-4XSFN6. That designation covers the 6 x 6 stainless steel, brushed finish, NEMA 4X feed through nipple section.
6) How much does the B-Line 66-4XSFN6 nipple section weigh for a one-person overhead install?
It weighs 4.683 lb, light enough to hold up and align by hand while setting fasteners on an overhead 6 x 6 run. Support and fastening hardware for the wireway run itself is separate.
