B-LINE 66-12LE45A – Frequently Asked Questions
1) Will the B-Line 66-12LE45A elbow fit 6x6 wireway?
Yes. The Eaton B-Line 66-12LE45A is sized for 6 inch by 6 inch wireway, with a 6 inch height and 6 inch width at the openings, so it mates to a 6x6 run on both legs. It will not adapt between two different trough sizes.
2) Is this wireway elbow rated for a washdown or dust-heavy area?
It is a NEMA 12 fitting, which covers indoor protection against falling dirt, circulating dust, lint and dripping non-corrosive liquids. That suits plant floors and dusty industrial spaces, not outdoor or hosedown locations where you'd need a NEMA 3R or 4 rated trough instead. It is UL Listed.
3) What does top opening mean on a 45 degree wireway elbow, and how does the cover come off?
Top opening means the removable cover is on the upper face of the elbow, so you open it from above rather than from the side. That matters when the elbow sits at eye level against a wall: you need clearance above it to lift the cover. It is a lay-in design, so conductors drop into the open trough and the cover goes back on, no pulling through a closed fitting.
4) Should I use a 45 degree elbow or a 90 degree elbow in a wireway run?
Use the 45 when the run has to change direction gently, for example jogging around a beam or structural obstruction, or when two 45s give you an offset that keeps the trough tight to the wall. A 90 is the choice for a square corner or a straight drop down a wall. The gentler 45 bend also eases conductor pulling stress compared with a hard 90.
5) Can I mix this Eaton B-Line elbow with another manufacturer's wireway?
Plan on keeping the whole run in the Eaton B-Line series. Wireway bolt patterns, flange dimensions and gasketing vary by maker, and a NEMA 12 rating only holds if the joints seal as the manufacturer intended. Matching a 6x6 B-Line lay-in trough to this 6x6 lay-in elbow is the way to keep the rating intact.
6) Is this B-Line wireway elbow steel or aluminum, and can I paint it?
Steel construction. It's a painted steel NEMA 12 fitting, so it takes field touch-up or an added finish coat fine. If your spec calls for stainless or aluminum because of corrosives, this is the wrong material for the environment.
7) How much does the 6x6 45 degree lay-in elbow weigh and how far does it project?
The fitting weighs 6 lb and has a length/depth of 4.46 inches, with 6 inch openings. That weight is light enough for one person to hold while bolting, but plan your hanger spacing so the elbow isn't carrying an unsupported trough leg on either side.
