B-LINE 4460 GRT NK – Frequently Asked Questions
1) Can the B-Line 4460 GRT NK wiring trough be used outdoors?
The 4460 GRT NK trough carries a NEMA 3R rating, so it's built for outdoor use where falling rain and sleet are the concern. It is not a washdown or hosedown enclosure. The body is steel in ANSI 61 gray with a screw cover held secure by a flange and plated screws, and it is CSA Certified.
2) Does the B-Line 4460 wiring trough come with knockouts for conduit?
No. The 4460 GRT NK is the NK (no knockouts) version, so the sides and ends come solid. You drill or punch your own openings wherever your conduit runs land. If you want factory knockouts, order a knockout version of the trough instead.
3) How does the B-Line 4460 trough mount to a wall or strut?
Mounting is through embossed thru holes in the back of the trough, so you fasten it directly to the wall, backboard, or strut with your own hardware. No separate mounting brackets or feet are part of the trough. At 18.02 lb empty for the 60 inch body, plan your fastener spacing for the loaded weight of the conductors as well.
4) What size is the B-Line 4460 GRT trough, and how much wire will 4 x 4 hold?
It's a 4 inch by 4 inch cross section, 60 inches long. The 4 x 4 inside dimension is the number that governs your fill, so size your conductor bundle against that square before committing. Length of 60 inches lets you span a run without couplings between panels.
5) Is the cover on this B-Line wiring trough hinged or screw-on?
Screw cover. The 4460 GRT NK uses a full-length cover retained by a flange and plated screws, which is what supports the 3R rating. If you expect to be in and out of the trough often, budget the time to pull and replace every screw, or specify a hinged-cover trough instead.
6) Is the B-Line 4460 GRT NK approved for use in Canada?
It is CSA Certified, which is the listing Canadian inspectors look for on a wiring trough. The model number to reference on a submittal is 4460 GRT NK from Eaton's B-Line series.
7) What gauge steel is the B-Line 4460 GRT NK trough made from?
16 gauge steel, finished in ANSI 61 gray. That's the standard weight for gutter and trough bodies in this size class, and it's stiff enough that a 60 inch run won't oil-can between mounting points when supported at reasonable intervals.
8) Will the ANSI 61 gray finish on this trough match my existing panels and enclosures?
ANSI 61 gray is the same standard gray used across most industrial electrical enclosures and switchgear, so the 4460 trough lines up visually with typical panelboards and control enclosures on a wall. For facilities standardizing a gear wall, that's the finish to ask for by name.
