B-LINE 6636 GRT NK – Frequently Asked Questions

1) Can the B-Line 6636 GRT NK wiring trough be used outdoors?
Yes. The 6636 GRT NK is a NEMA 3R trough, so it is built for outdoor use where falling rain, sleet and external ice formation are the concern. The screw cover seats against a flange and is held by plated screws, which is what keeps water out of the top of the box. NEMA 3R is not a washdown or dust-tight rating, so for hosedown or heavy dust areas you want a 4 or 12 enclosure instead.
2) What size is the B-Line 6636 wiring trough and how much wire space does it give me?
It is a 6 by 6 inch cross section, 36 inches long. That gives 36 square inches of interior cross-sectional area before deductions, which is the number you work from when sizing conductor fill and counting splices in a wireway. The 36 inch length is the common straight run section, and troughs of this type are coupled end to end for longer runs.
3) Does the 6636 GRT NK trough come with knockouts?
No. The NK in the model designation means no knockouts, so every conduit entry is field-drilled or punched where you want it. That is the right choice when your conduit layout does not line up with a factory knockout pattern, but it does mean you need a hole saw or punch on site, plus your own connectors and closure plugs.
4) Is the Eaton B-Line 6636 GRT NK trough certified for use in Canada?
It carries CSA Certification, which is the listing Canadian inspectors look for on a wireway. Combined with the NEMA 3R rating, it suits outdoor and unheated locations on projects on either side of the border.
5) Screw cover or hinged cover trough, which do I want?
The 6636 GRT NK is a screw cover trough: the cover is captured by a flange and plated screws along the length. That is what you want for a pull and splice box that gets opened rarely, and it is the type an inspector expects on an outdoor 3R run. If the trough is in a spot you will be opening weekly for terminations or changes, a hinged cover version saves the screw work, at the cost of a bulkier profile.
6) What gauge steel is the B-Line 6636 GRT wiring trough, and what color is it?
16 gauge steel, finished in ANSI 61 gray. That is the standard light gray used on most switchgear, panelboards and enclosures, so a run of these will match existing gear in a typical industrial or commercial room rather than standing out.
