B-LINE 66-12LTSC – Frequently Asked Questions

1) What does a transposition wireway section like the B-Line 66-12LTSC actually do in a wireway run?
A transposition section changes the orientation of the wireway run so conductors can be carried through a rotation in the raceway. The 66-12LTSC is the clockwise version, so the rotation direction has to match the way your run turns. If your layout rotates the other way, you need the counterclockwise fitting instead, not this one.
2) Will the 66-12LTSC fit a 6 x 6 wireway run?
Yes. The fitting is a 6 inch by 6 inch cross section, matching standard 6 x 6 wireway body, and it measures 11.94 inches in the length/depth direction. It will not adapt between two different wireway sizes, so both ends of your run need to be 6 x 6.
3) Is this B-Line wireway fitting rated for a dusty or dripping industrial environment?
It is a NEMA 12 fitting, so it is built for indoor use with protection against falling dirt, circulating dust and dripping non-corrosive liquids. It is not a washdown or outdoor rating. The sealing plate kit that ships with it is what maintains that enclosure integrity at the joint.
4) How do I make sure I order the right handed transposition section, clockwise or counterclockwise?
Sight along the wireway in the direction the conductors travel and note which way the section has to rotate. The 66-12LTSC is the clockwise unit. Ordering the wrong hand means the joint bolt patterns and the run orientation will not line up, so confirm the rotation on the drawing before you order.
5) Do I need to buy a gasket or sealing kit separately for this transposition section?
No. One sealing plate kit ships with the 66-12LTSC. What is not included is the connecting hardware or the wireway body itself, so order your straight sections and any additional fittings to complete the run.
6) Is the B-Line 66-12LTSC UL Listed for use on an inspected commercial job?
Yes, it carries a UL Listing, which is what most inspectors look for on wireway and its fittings in commercial and industrial installations.
7) What is this wireway fitting made of and how is it finished?
Steel, painted ANSI 61 gray, which is the standard gray used across Eaton B-Line wireway so the fitting matches the straight sections and elbows already in the run. It weighs 9.25 lb, light enough for a single installer to set in place on a wall-mounted run.
