The 6648 G is a 6 x 6 inch cross section, 48 inches long. That gives a nominal 36 square inch internal area before deductions, and NEC practice limits fill to 20 percent of the cross section for conductors running straight through. It is a screw-cover trough, so the cover comes fully off for laying conductors in rather than pulling them.

No. It is a NEMA 1 enclosure, which is indoor, dry location only, protecting against incidental contact and falling dirt. It is not sealed against rain, washdown, or dust. For an exterior run or a wet area you need a NEMA 3R raintight trough instead.

Yes. A 6648 G is a straight 48 inch trough section only. Connectors, couplings, end plates, elbows, and tees are separate items, and so are the mounting fasteners. Plan the run so every joint, corner, and termination has its own fitting on the order.

The cover is secured with plated screws and lifts completely off once they are out. That is the right choice for a run you lay up once and rarely reopen. If you are in a panel room where the trough gets opened repeatedly for adds and moves, a hinged-cover wireway saves the screw handling, at the cost of needing swing clearance in front of the trough.

Yes, 15 knockouts on the top and 15 on the bottom, so conduit can land on either face without field drilling along most of the 48 inch length. The sides and ends are not pre-punched for those, so any side entries are field work.

It is CSA Certified. That is the certification carried on the trough itself; specify accordingly if your submittal calls out a particular listing agency.

16 gauge steel, finished in ANSI 61 gray, which is the standard gray used on switchgear and panelboards, so a run will match adjacent electrical equipment in a typical commercial room.
