B-LINE 121248 GTGV NK – Frequently Asked Questions
1) What size is the B-Line 121248 wiring trough?
The 121248 GTGV NK trough is a 12 x 12 x 48 inch body: 12 inches high, 12 inches wide, and 48 inches long. That is the standard 12x12 cross section, so it lines up with other 12-inch trough sections and fittings when you build out a run along a wall of panels.
2) Does this Eaton B-Line trough come with a knockout pattern, or is it blank?
It is the NK version, meaning no knockouts. The sides, ends and bottom come blank, so you punch or drill only where your conduit actually lands. If you want factory knockouts to speed up a repetitive install, you need a knockout version instead of the NK.
3) How is this wiring trough mounted to the wall or to a panel?
Mounting is through the enclosure itself, via thru holes, so you fasten it directly to the wall, strut, or backing with your own hardware. At about 48 lb empty, get it on solid backing or strut and support both ends of the 48 inch length before you load conductors into it.
4) How does the cover come off on the 121248 GTGV trough, and can I get to the wire once it is mounted?
The cover is a screw cover, held on with plated screws. You back the screws out to open the full length of the trough for pulling or splicing, then screw it back down. It is not a hinged or latched cover, so plan on needing a driver and clearance in front of the trough every time you open it.
5) Is this trough certified for use on a Canadian job?
The 121248 GTGV NK carries CSA C22.2 certification, which is what an inspector on a Canadian installation will be looking for on the enclosure label.
6) What finish does the B-Line 121248 trough come in, and will it match existing gray enclosures?
Gray, which is the usual finish for indoor electrical enclosures and panelboards, so it reads consistently alongside gray gutter and panel gear already on the wall. If your facility standard is a different color you would be painting it.
