B-LINE 4472 GTGV NK – Frequently Asked Questions

1) Does the B-Line 4472 GTGV NK trough come with knockouts, or do I have to punch my own holes?
No knockouts. The NK in the 4472 GTGV NK designation means the body ships blank, so every conduit entry is one you punch or drill where your run actually lands. If you want factory openings on a pattern, you need a knockout version instead of the NK.
2) Is a NEMA 1 galvanized wiring trough OK outdoors or in a wash-down area?
Indoors only. The 4472 GTGV NK is a NEMA 1 enclosure, which is general purpose indoor protection against incidental contact and falling dirt, with a screw-on cover rather than a gasket. Rain, hose-down, or dust-laden air calls for a rated raintight or dust-tight trough, not this one.
3) How does the cover come off the B-Line 4472 trough when I need to pull more wire later?
Plated screws hold the cover down along its length, so pulling the cover is a screwdriver job, not a hinged or latched one. Plan for access room above the trough and budget the time if you expect to reopen it often; a hinged-cover trough is the faster choice on a panel you revisit weekly.
4) Is the B-Line 4472 GTGV NK trough heavy enough gauge for a commercial install?
Body steel is 16 gauge, galvanized, which is the usual weight for a screw cover trough carrying feeders and branch conductors on an equipment wall. Galvanized rather than painted means the finish holds up in a mechanical room or parking garage ceiling where a painted enclosure would start showing rust at the cut edges.
5) Does the B-Line 4472 GTGV NK carry a CSA listing for a Canadian job?
Certification on the 4472 GTGV NK is CSA C22.2, so it can go on a job specifying CSA certified electrical enclosures. That is the certification carried on the trough itself.
6) What color is the B-Line 4472 wiring trough, and will it match the rest of my gear?
Gray, over galvanized steel, with plated screws on the cover. It reads as standard electrical gray next to typical panelboards and disconnects, so it does not stand out on an equipment wall.
