B-LINE 4466 FR – Frequently Asked Questions

1) What does the B-Line 4466 FR wireway reducer actually do?
It's a transition fitting for lay-in wireway, model 4466 FR from the Eaton B-Line series. It joins one wireway size to another so a run can step down (or up) without cutting and patching duct. It uses the HSCA adapter style connector, so it attaches to the wireway sections rather than being a length of duct itself.
2) Is this reducer rated for outdoor or wet locations?
No. It is a NEMA 1 (Type 1) fitting, which is general purpose indoor only, meant to keep hands out and limit falling dirt. For rooftops, exterior walls, washdown areas or anywhere water can reach the duct, you need a NEMA 3R or 4 raintight wireway fitting instead. Mixing a Type 1 reducer into a raintight run breaks the rating of the whole run.
3) What wireway sizes does the 4466 FR reduce between?
It transitions between 4 x 4 inch wireway and 6 inch wireway. The name calls out the 4" x 4" side, and the fitting body measures 4 inches high, 6 inches wide and 10 inches long, so the larger opening is the 6 inch side. Confirm the duct you're tying into matches those two openings before you order.
4) Is the B-Line 4466 FR UL Listed?
Yes, the 4466 FR reducer is UL Listed. That matters on inspected commercial and institutional work, where a listed fitting is expected throughout a wireway run and not just on the duct sections.
5) Will the finish match the wireway already installed in my panel room?
It's painted ANSI 61 gray, the standard gray used on most commercial wireway, enclosures and gear, so it will blend with an existing B-Line lay-in wireway run. The body is steel, so if the surrounding duct is stainless or aluminum this reducer will not match it and won't suit a corrosive area.
6) Do I need a reducer or a wireway coupling for my run?
Use a reducer only where the duct size changes, here between a 4 x 4 inch and a 6 inch opening. If both sections are the same size, a straight coupling or connector is the right part. Buying a reducer to join equal-size duct leaves you with a mismatched opening to plate over.
7) How much does the 4466 FR reducer weigh, and can one person hang it?
3.582 lb. It's a one-hand piece on a ladder; the support you plan for is for the wireway sections either side of it, not the fitting.
