The 8824 G is an 8 x 8 inch cross section, 24 inches long. That 8 x 8 opening is what determines your wire fill and how easily you can pull conductors through at a pull point, and the 24 inch run is a common length for tying a short gap between panels or gutter sections.

No. The 8824 G is a NEMA 1 enclosure, which is indoor, general purpose only. It keeps personnel away from live parts and blocks falling dirt, but it is not sealed against dripping water, washdown, or weather. For an exterior wall, a rooftop run, or anywhere hose-down or rain reaches it, you need a raintight gutter rather than this one.

Knockouts are already provided: 7 on the top and 7 on the bottom of the 24 inch body. For conduit entries on the sides or ends outside those locations, you punch your own. Plan your conduit layout against the existing top and bottom pattern first, since using the factory knockouts keeps the gauge steel intact and saves field time.

It is a screw cover, secured with plated screws around the perimeter. That gives a tight, tamper-resistant closure, but every time you open it you are backing out screws and putting them back. If your electricians will be in and out of the gutter regularly for troubleshooting or adds, a hinged cover version is the easier choice; for a pull point or splice box that gets closed and stays closed, the screw cover is fine.

Mounting is through holes in the body, so it bolts or screws directly to a wall, backboard, or strut. At 13.54 lb empty it is a one-person hang, but load it with conductors and the fasteners have to carry the filled weight, so anchor into studs, strut, or backboard plywood rather than drywall alone.

The 8824 G is CSA Certified. That is the certification carried on this gutter, and it is the one an inspector or spec reviewer will be looking for on the label.
