B-LINE 66-12FN2 – Frequently Asked Questions
1) What does a wireway nipple section actually do in a run of 6x6 wireway?
The Eaton B-Line 66-12FN2 is a short feed-through section used to join two wireway bodies or tie a wireway to an enclosure. It is a feed-through wiring method, so conductors pass straight through rather than terminating in it. The body measures 6 by 6 inches with a 1.938 inch length/depth, so it is a coupling-length piece, not a full trough run.
2) Is this wireway nipple section rated for wet or washdown areas?
No. The 66-12FN2 carries a NEMA 12 rating, which covers indoor protection against dust, falling dirt and dripping non-corrosive liquids. It is not a wet-location or washdown rating. For hosedown or outdoor work you need a NEMA 4 or 4X rated wireway instead.
3) Do the two nipples come on the B-Line 66-12FN2 or do I add them?
The section is supplied as a two-nipple feed-through piece, so both nipple connections are part of the assembly. What you still need to plan for on the order is the gasketing and hardware practice for your NEMA 12 run, plus the wireway bodies and covers themselves, which are separate items.
4) Is the 66-12FN2 UL Listed for a specification job?
Yes, it is UL Listed, which is usually what a spec or an inspector asks for on a wireway feed-through in an industrial panel room. Pair that with the NEMA 12 rating when you are documenting the run for submittal.
5) Can I use a feed-through nipple section where I need to tap conductors off to a panel?
Not for splicing or terminating. The 66-12FN2 is a feed-through section, meaning conductors run straight through it from one wireway body to the next or into an adjoining enclosure. If you need to pull and redirect conductors, use a full wireway section or a pull/junction box with the working space to do it.
6) Is this nipple section steel or aluminum, and how heavy is it to handle overhead?
Steel construction, at 2.728 lb. That is a one-hand piece on a ladder, so a single electrician can set it between two wireway bodies without a helper. Being steel, it needs the painted finish kept intact in any area where corrosion is a concern.
