B-LINE 66-12LTC – Frequently Asked Questions
1) Will the B-Line 66-12LTC tee fit 6x6 wireway?
Yes. The 66-12LTC is sized for 6 inch by 6 inch wireway, and its cataloged width is 6 inches. It joins three runs of 6x6 lay-in wireway at a right-angle branch, so all three legs need to be the same 6x6 trough size.
2) Is this B-Line wireway tee rated for a dusty or washdown industrial area?
It is a NEMA 12 rated tee fitting, which covers dust, falling dirt and dripping non-corrosive liquids. NEMA 12 is not a hosedown or outdoor rating, so for washdown or wet exterior runs you need NEMA 3R or 4 wireway and fittings instead. The 66-12LTC is also UL Listed.
3) Do I need to buy sealing plates separately for this wireway tee?
No. Two sealing plate kits ship with the 66-12LTC tee, which is what maintains the NEMA 12 seal where the fitting meets the wireway trough. You still supply the wireway sections themselves and any connectors those sections require.
4) What does "outside opening" mean on this B-Line tee fitting?
The wiring method is outside opening, meaning the conductor openings are on the outside faces of the fitting body where it laps over the ends of the wireway trough. Practically, you lay conductors in from the removable side and pull them through those outer openings into the branch run rather than through an internal knockout.
5) How much room do I need to allow for the B-Line 66-12LTC tee in my layout?
Plan on 12.88 inches of length and 2.5 inches of height on the published dimensions, with a 6 inch width matching the trough. Take the 12.88 inch figure off your straight wireway length when you lay out a branch, since the tee occupies that much of the run.
6) Is this wireway tee steel or aluminum, and what is the paint finish?
Steel construction with an ANSI 61 gray painted finish, which is the standard gray used across B-Line wireway and most industrial enclosures, so it matches existing gray trough and panel work. If your specification calls for stainless or aluminum for corrosive duty, this painted steel fitting is not the right choice.
7) What part number do I order for a B-Line 6x6 NEMA 12 wireway tee?
Order Eaton B-Line 66-12LTC. That is the 6x6, NEMA 12, steel, ANSI 61 gray tee with two sealing plate kits included.
8) How heavy is the 66-12LTC tee for overhead support planning?
The fitting weighs 11.765 lb on its own, before conductors. For a suspended 6x6 run, add that to your hanger loading at the branch point and keep supports close to the tee on both the through run and the branch leg.
