B-LINE 6618 GRTGV NK – Frequently Asked Questions

1) Can the B-Line 6618 GRTGV NK wiring trough be used outdoors?
It is built to NEMA 3R, which covers outdoor use against falling rain and sleet, so it will work on an exterior wall or in a wet-location run where the enclosure is mounted upright. Construction is galvanized steel, 16 gauge, finished gray, with plated screws holding the cover. It is not a washdown or hosedown enclosure, so keep it out of direct spray.
2) What size is the B-Line 6618 wiring trough, and how much wire fits?
The body is 6 inches high by 6 inches wide by 18 inches long, so you get a 6 x 6 inch cross section for the run. That is the usable gutter area for conductors and splices, and it is the size electricians spec when they need pull and splice space alongside a panel without going up to an 8 x 8.
3) Does this B-Line trough come with knockouts already punched?
No. The 6618 GRTGV NK is the NK (no knockouts) version, so every conduit entry gets field punched or hole sawed where you want it. That is the right choice when the trough is feeding multiple panels or the layout is not settled; if you want factory openings, order a knockout version instead.
4) How does the cover come off on the B-Line 6618 GRTGV NK, and how is the trough mounted?
It is a screw cover, held by a flange and plated screws, so the whole cover lifts off for wire pulling rather than hinging. Mounting is through embossed thru holes in the back, which let you lag or bolt it straight to a wall or strut without drilling the enclosure. The unit weighs 9.065 lb, so a single installer can hang it.
5) Does the B-Line 6618 GRTGV NK trough carry a Canadian listing for a job north of the border?
It is built to CSA C22.2, which is the Canadian electrical enclosure standard, so it can be specified on Canadian work as well as US.
6) What part number do I order for this 6x6x18 B-Line screw cover trough?
The manufacturer part number is 6618 GRTGV NK from Eaton B-Line. The 6618 is the 6 x 6 x 18 size, GRTGV is the gray galvanized screw cover trough, and NK means no knockouts.
7) Is the 16 gauge steel on this wiring trough heavy enough for a commercial job?
16 gauge galvanized steel is the standard body thickness for gutter and trough of this size, and it holds shape when you are pulling conductors through a 6 x 6 section. The galvanized base plus gray finish is what gives it the corrosion resistance the 3R rating needs outdoors.
