B-LINE 4448-12WT – Frequently Asked Questions
1) What size wireway is the B-Line 4448-12WT, and how much wire space does it give me?
It's a 4 x 4 inch cross section, 48 inches long. That 4 by 4 inside profile is the standard size for feeder taps and gutter work between panels and disconnects, and the 48 inch run lets you span a typical panel-to-panel gap without a coupling.
2) Is this wiring trough rated for washdown or oily environments?
The 4448-12WT is a NEMA 12 trough, so it's built for indoor use against falling dirt, dust, dripping non-corrosive liquids, and lint. It is not a washdown or outdoor enclosure. If you're hosing the area down or running it outside, you need a NEMA 4 or 4X wireway instead.
3) How does this B-Line trough mount to the wall or strut?
It has welded external mounting feet, so the feet are already on the body and you fasten through them to the wall, backboard, or strut. No separate mounting bracket kit to order, and because the feet are external, nothing pierces the wireway interior to compromise the NEMA 12 seal.
4) How does the cover open on the B-Line 12WT trough, and can I get to the wire with the trough mounted tight to a wall?
The cover is hinged, held shut with heavy-duty hinges and screw clamps. You swing it open rather than lifting a loose lid off, so nothing gets dropped off a ladder and you can pull wire with one hand. It does need swing clearance on the hinge side, which matters when you're mounting into a corner or under a panel.
5) What gauge steel is the 4448-12WT and does one person need help hanging it?
Body is 14 gauge steel finished in gray, and the 48 inch unit weighs 21.053 lb. That's a one-man lift onto pre-set fasteners for most installers, though a second set of hands helps when you're setting it overhead at height.
6) What keeps water and dust out of the seam on this wireway?
The gasket is a seamless poured in-place type, formed directly on the enclosure rather than cut and glued at a joint. No butt seam at the corner is the usual failure point on a NEMA 12 gutter, so this is what holds the dust and drip rating over repeated openings.
7) Is the B-Line 4448-12WT approved for Canadian jobs?
It carries CSA C22.2 certification, so it's acceptable for work under the Canadian Electrical Code as well as US installs.
8) What part number do I order for the 4 x 4 x 48 inch hinged NEMA 12 B-Line trough?
Order Eaton B-Line 4448-12WT. The number reads straight off the geometry: 4 inch by 4 inch cross section, 48 inch length, 12WT for the NEMA 12 wiring trough series.
