B-LINE 666 RTSCGV NK – Frequently Asked Questions
1) Can the B-Line 666 RTSCGV NK junction box be mounted outdoors?
Yes. The Eaton B-Line 666 RTSCGV NK is a NEMA 3R enclosure, which means it is built for outdoor use against rain, sleet and falling dirt, not for washdown or submersion. It uses galvanized steel construction and carries a rainhood over the screw cover to shed water. It is UL 50 listed.
2) Does the B-Line 666 RTSCGV NK come with knockouts for conduit?
No. The NK in the model designation means no knockouts, so the box ships blank on all sides and you drill or punch your own conduit entries wherever the run needs them. Plan on a step bit or knockout punch and the appropriate rain-tight hub or fitting, since drilling a 3R enclosure on the top surface will compromise the rating unless you use a raintight fitting.
3) Is a NEMA 3R box like this good enough for a wet location or a washdown area?
No. 3R protects against falling rain and sleet, not directed spray, hose-down or dust ingress. For a washdown kitchen, a car wash or a food plant you want a 4 or 4X enclosure, and 4X stainless if there are chemicals. Use the 666 RTSCGV NK for exterior walls, rooftop runs, and similar rain-exposed but not sprayed locations.
4) What are the actual box dimensions on the B-Line 666 junction box?
It is a 6 x 6 x 6 inch enclosure: 6 inch height, 6 inch width, and 6 inch length/depth. Shipping weight is about 4 lb. The cube shape gives you the same depth as face opening, which is useful when you need wire-bending room for larger conductors in a small footprint.
5) How does this B-Line enclosure mount to a wall?
Surface mounting, using embossed thru holes formed into the back of the box. The mounting provisions are embossed so fasteners seat outside the wiring space and the enclosure stands slightly off the wall. Fasteners for the wall are not part of the box, so pick anchors to suit your substrate.
6) Is the cover hinged or does it screw on?
Screw cover. The 666 RTSCGV NK uses a plated-screw cover rather than a hinged door, so access means backing out the screws with a driver. For a box you open often, a hinged-cover enclosure is the better choice; a screw cover is standard on pull and junction boxes that are wired once and left.
7) What is the exact part number to order this 6x6x6 B-Line NEMA 3R screw cover box?
Order Eaton B-Line part number 666 RTSCGV NK. Reading the code: 666 is the 6 x 6 x 6 inch size, RTSC is the rain tight screw cover style, GV is galvanized, and NK is no knockouts. It is made in the US.
8) What gauge steel is the B-Line 666 junction box made from, and will it hold up outdoors?
16 gauge galvanized steel. The galvanizing is mill applied rather than painted, so the box ships unfinished with a grey metallic appearance and needs no coating for normal outdoor service. If it is going somewhere that needs a colour match, you would paint it or specify a painted enclosure instead.
