B-LINE 44-12LE45C – Frequently Asked Questions
1) Will the B-Line 44-12LE45C elbow fit a 4 x 4 inch wireway run?
Yes. The Eaton B-Line 44-12LE45C is sized for 4 x 4 inch wireway, with a 4 in height and 4 in width at the openings and a 3.51 in length/depth on the body. It turns the run 45 degrees. If your trough is 6 x 6 or larger, this is the wrong size fitting.
2) What does "top opening" mean on a 45 degree wireway elbow, and does it change how I mount it?
Top opening means the removable cover is on the top face of the elbow, so you drop conductors in from above rather than pulling them through. That suits a horizontal run turning 45 degrees where you can reach the top of the trough. If your run is vertical against a wall, or the top face will be tight to a ceiling or structure, you want a side or front opening fitting instead so the cover can still come off after install.
3) Can this B-Line wireway elbow be used in a dusty or washdown plant area?
It carries a NEMA 12 rating, which covers dust, falling dirt and dripping non-corrosive liquids in an indoor industrial space. NEMA 12 is not a wet-location or outdoor rating, so for rain, hose-down or sleet exposure you need a NEMA 3R or 4 wireway system instead. The fitting is UL Listed.
4) Is this a lay-in elbow or do I have to pull wire through it?
It's lay-in. The wiring method on the 44-12LE45C is lay-in, so with the cover off you set conductors into the elbow and close it up, no pulling around the 45 degree bend. That is the practical reason electricians use wireway instead of conduit on a dense feeder run.
5) Does the 44-12LE45C need to match the rest of my wireway for the NEMA 12 rating to hold?
Yes. A NEMA 12 enclosure rating only holds if every trough, fitting and cover in the run is NEMA 12 and the joints are made up with the system's gasketing and hardware. Mixing a NEMA 1 trough into the run drops the whole assembly to the lower rating. Match the 44-12LE45C to 4 x 4 NEMA 12 lay-in wireway from the same series.
6) Should I use a 45 degree elbow or two 90s to route wireway around an obstruction?
A 45 degree elbow like the 44-12LE45C makes a shallower turn, which keeps conductor bending gentler and eats less linear space than stacking 90s. Use a pair of 45s to offset a run around a beam or pipe; use a 90 when you need a hard square corner into a panel or down a wall. Both are lay-in on this series, so neither adds a pull.
7) What part number do I order for the Eaton B-Line 4 x 4 NEMA 12 lay-in 45 degree top opening elbow?
Order model 44-12LE45C. That is the Eaton B-Line series steel elbow, 45 degrees, top opening, lay-in, NEMA 12, sized 4 x 4 inch. One model covers this configuration, so there is no finish or handing to specify.
