B-LINE 66-12FN6 – Frequently Asked Questions
1) What is a wireway nipple section used for on a 6x6 wireway run?
A nipple section is the short coupling piece that joins two wireway components or connects a wireway to an enclosure, letting conductors feed straight through from one body to the next. The Eaton B-Line 66-12FN6 is the feed-through version for 6 inch by 6 inch wireway, so it carries wire between sections rather than providing a pull point or a change of direction.
2) Is the B-Line 66-12FN6 nipple rated for washdown or oily, dusty industrial areas?
It is built to NEMA 12, which covers indoor protection against falling dirt, circulating dust, lint, and dripping non-corrosive liquids. That suits machine shops, plants, and other dusty or drippy indoor spaces. It is not a NEMA 4X washdown or outdoor rating, so for hosedown or wet exterior locations you need a different wireway family.
3) Is this wireway nipple UL Listed for an inspected commercial job?
Yes, the B-Line 66-12FN6 nipple section carries a UL Listing, which is what most AHJs want to see on wireway and its fittings in commercial and industrial installs.
4) What are the actual dimensions and weight of the 66-12FN6 nipple section?
Published figures are 8 in height, 8 in width, and 5.938 in length/depth, at 4.637 lb. The 8 by 8 face reflects the flange on a 6 by 6 wireway body, so allow for that overall footprint when you are laying out tight spacing between an enclosure and the run.
5) Do I order a feed-through nipple or a pull box when connecting wireway to a panel?
Use a feed-through nipple like the 66-12FN6 when conductors simply pass from the wireway into the panel or the next section with no splicing or redirection at that point. If you need slack, splices, or a change of direction, a pull box or an elbow/tee fitting is the piece to specify instead. The nipple is the shortest, least expensive way to bridge the two.
6) What exact part number do I give my distributor for this B-Line nipple?
Order Eaton B-Line part number 66-12FN6. That single number covers the NEMA 12 steel feed-through nipple section for 6 by 6 wireway; there are no finish or size options to specify with it.
7) Is the B-Line nipple steel or aluminum, and does it need painting?
The body is steel. Eaton B-Line NEMA 12 wireway in this line ships finished from the factory, so no field painting is needed for a normal indoor install. If your spec calls for stainless or aluminum because of the environment, this steel part is not the right substitution.
