B-LINE 4448-12LW – Frequently Asked Questions

1) Is the Eaton B-Line 4448-12LW wireway rated for washdown or oily environments?
Model 4448-12LW is a NEMA 12 wireway with an oil-resistant gasket under the cover, so it is built for dust, falling dirt, and dripping non-corrosive liquids and coolant in plants and shops. NEMA 12 is not a washdown or hosedown rating, so for direct spray or outdoor exposure you want a NEMA 4 or 4X trough instead.
2) What size cross section is this B-Line wireway, and how long is each stick?
It is a 4 x 4 inch cross section running 48 inches per length. That 4 x 4 lay-in trough is the standard size for feeder and control wiring pulls where a 6 x 6 would be oversized, and the 48 inch stick is the common length for running between panels on a wall.
3) Does the cover come off, or is it hinged?
The cover is hinged, held by heavy-duty butt hinges with quick-release latches. You swing it open for a lay-in pull and it stays attached to the trough, so nothing gets dropped off a lift or lost on the floor. If your run is tight to a ceiling or adjacent equipment, check that you have swing clearance on the hinge side before you set the trough.
4) What gauge steel and finish is this B-Line lay-in wireway?
14 gauge steel finished in ANSI 61 gray. That is the standard gray used on switchgear and panelboards, so a run of this trough matches existing electrical equipment on an industrial wall without repainting.
5) Is this wireway approved for use on a Canadian job?
It carries CSA C22.2 certification, which is what an inspector on a Canadian installation is looking for on a wireway. Specifiers pulling this into a submittal can cite that listing along with the NEMA 12 enclosure type.
6) Can I extend a 4 x 4 wireway run past 48 inches with this part?
Yes. The 4448-12LW is one 48 inch section of the 12LW series, and runs are built by coupling sections of the same 4 x 4 cross section end to end with connectors. Keep every section in the run at the same 4 x 4 size and NEMA 12 gasketed type so the enclosure rating holds through the joints.
