B-LINE 6688-3RASCR – Frequently Asked Questions
1) What does a wireway reducer fitting do, and when do I need one?
A reducer fitting is what you use when a wireway run steps from one trough size down to another. The Eaton B-Line 6688-3RASCR is a reducer fitting that joins the two sections so the raceway stays continuous and enclosed through the transition instead of ending at an open cut. You order it when the drawing shows a larger trough feeding a smaller one, typically where the conductor fill drops off past a pull point.
2) Can the B-Line 6688-3RASCR reducer be used outdoors?
Yes. It carries a NEMA 3R degree of protection, which is the rating for outdoor enclosures that handle rain, sleet and snow, so it suits exterior wireway runs, rooftops and equipment yards. It is not a washdown or hosedown rating, so for direct water jets or heavy dust you want a 4 or 4X family fitting instead.
3) Is the B-Line wireway reducer UL Listed?
It is UL Listed, which is what most inspectors and spec writers look for on wireway fittings in commercial and institutional work. That listing applies to the reducer fitting itself as supplied.
4) Why choose an aluminum wireway reducer over a painted steel one?
The 6688-3RASCR body is aluminum, which is the usual pick for outdoor and coastal or damp installs where a painted steel trough will eventually rust at cut edges and screw holes. Aluminum is also lighter to handle overhead, this fitting weighs 2.291 lb. Painted steel is the more common choice for dry indoor runs where corrosion is not a concern.
5) Do I need to order anything else to make up the wireway run besides the reducer?
The reducer is one fitting in a system. A complete run also needs the straight wireway sections on each side of the transition, plus any elbows, tees, end plates and hanger or support hardware the layout calls for. The 6688-3RASCR handles the size change only.
6) What part number do I quote for the B-Line 3R aluminum wireway reducer?
Order it as Eaton B-Line 6688-3RASCR. That is the manufacturer part number for the NEMA 3R aluminum wireway reducer fitting, and the single configuration offered.
