B-LINE 44-12FN2 – Frequently Asked Questions
1) What is a wireway nipple section used for on a 4x4 wireway run?
A nipple section is the short connecting piece that joins two wireway components or ties a wireway directly to an adjacent enclosure or panel. The Eaton B-Line 44-12FN2 is sized for 4 inch by 4 inch wireway and is a feed through section, so conductors pass straight through it rather than terminating. Its length is 1.938 inches, which is why it is used where two boxes or troughs sit nearly flush and a full-length straight section will not fit.
2) Is the B-Line 44-12FN2 nipple rated for a washdown or oily indoor area?
It carries a NEMA 12 rating, which is the indoor rating for protection against dust, falling dirt and dripping non-corrosive liquids. That covers most industrial plant floors, food processing support areas and machine shops. It is not a NEMA 4 or 4X part, so direct hose-down or outdoor exposure calls for a different rating. The section is also UL Listed.
3) What part number should I give my distributor for the B-Line 4x4 NEMA 12 feed through nipple?
Specify Eaton B-Line 44-12FN2. The 44 indicates the 4 inch by 4 inch wireway size, 12 the NEMA 12 rating, and FN the feed through nipple section. It is steel and UL Listed.
4) Is the Eaton B-Line wireway nipple steel or aluminum?
Steel. That is the standard material for NEMA 12 indoor wireway, and it means the section is painted rather than corrosion resistant on its own. In damp or chemical environments where you would normally specify stainless or aluminum, this is not the part to use.
5) How much does a 4x4 wireway nipple section weigh for overhead support planning?
The 44-12FN2 weighs 1.657 lb. At under two pounds it adds essentially nothing to a trapeze or strut-supported run, so support spacing is driven by the full-length wireway sections and the conductor fill, not by the nipple.
6) Does a nipple section come with the hardware to connect two wireway sections?
Order it as a connecting piece for 4x4 NEMA 12 wireway and plan on the gasketing and fasteners specified for your wireway system. What the nipple itself provides is the short 1.938 inch feed through body between two openings; conductors run straight through with no splice point inside it.
