B-Line Eaton series wiring trough, 6" height, 72" length, 6" width, HS wireway, Thru holes, 23 top knockouts, 23 bottom knockouts, Hinged cover, 1, S

No. The 6672 HS trough is a NEMA 1 enclosure, which means indoor, dry locations only. It gives you protection against falling dirt and incidental contact, nothing more. For a wet or outdoor run you need a NEMA 3R raintight wireway instead, and the two are not interchangeable even though the cross sections match.

It is a 6 x 6 inch cross section, 72 inches long, giving 36 square inches of interior cross sectional area. NEC wireway fill is limited to 20 percent of that cross section, so you have roughly 7.2 square inches of conductor area to work with before you are over fill. Size your conductors off that number rather than off the trough's outside dimensions.

It ships with 23 knockouts on the top and 23 on the bottom, so conduit entries along the run are already provided and you are not drilling a painted enclosure in the field. If your entry points do not line up with the punched pattern, you can still hole saw the 16 gauge steel body, but the knockout spacing usually covers a typical panel or gutter feed layout.

Yes, the trough is certified to CSA C22.2, which is what an inspector in Canada will be looking for on a wireway. Keep in mind it is a NEMA 1 indoor enclosure, so the certification does not extend its use to damp or outdoor runs.

A 6 x 6 section suits control wiring, branch circuit gathering, and moderate panel-to-panel runs where the 20 percent fill on 36 square inches of cross section is enough. Once you are pulling several sets of large feeders, or you need bending room at taps and splices, step up to a deeper trough instead. Bending space at the knockouts, not just fill area, is usually what forces the bigger box.

16 gauge steel, finished in ANSI 61 gray. That is the standard gray used on most switchgear and panelboards, so the trough matches gear already on the wall in an electrical room and you are not looking at a mismatched gutter above a lineup.

Yes, wireway of this type is commonly used for splices and taps as well as straight raceway, and the hinged cover makes those splices accessible later without unscrewing a full length of cover. Splice fill in a wireway is limited to 75 percent of the cross sectional area at that point, so with a 36 square inch section keep the splice bundle well inside that.
