B-LINE 18186 RTSCGV NK – Frequently Asked Questions

1) Can the Eaton B-Line 18186 RTSCGV NK junction box be mounted outdoors?
Yes. The 18186 RTSCGV NK is a NEMA 3R enclosure, which means it is rated for outdoor use against falling rain, sleet and snow. The screw cover carries a rainhood and the body is galvanized steel. NEMA 3R is not a washdown or hosedown rating, so for direct spray or heavy dust you want a 4 or 4X box instead.
2) What are the box dimensions on the 18186 RTSCGV NK enclosure?
18 inches high, 18 inches wide and 6 inches deep, which is where the 18186 designation comes from. That 6 inch depth is the number to check first if you are stacking terminal blocks or landing large conduit bodies inside.
3) Does this B-Line enclosure come with knockouts for conduit?
No. The RTSCGV NK is a no-knockout box, so every conduit entry has to be field punched. Plan on a hole saw or punch set and appropriate raintight fittings if the box is going outdoors, since a 3R rating only holds if your entries are made weathertight.
4) How does this junction box mount to a wall, and do I need to drill through the back?
It is surface mounted using embossed thru holes formed into the back of the enclosure, so the mounting provisions are already there and you are not drilling the box. At 18.1 lb empty, anchor into studs or use masonry anchors rated for the loaded weight once wire and devices are inside.
5) Is the 18186 RTSCGV NK a hinged door box or a screw cover?
Screw cover. The cover comes off entirely with plated screws rather than swinging on a hinge, which means you need clearance in front of the box and a free hand for the cover when you open it. It is catalogued as a medium single door style. For frequent access, a hinged-cover enclosure is the easier choice.
6) Is this enclosure UL listed for a commercial or institutional job spec?
The 18186 RTSCGV NK is built to UL 50, the standard covering enclosures for electrical equipment, and it is US made. That plus the NEMA 3R rating is usually what a submittal asks for on outdoor junction boxes.
7) What gauge steel is this B-Line enclosure, and does it need painting?
16 gauge galvanized steel, supplied unfinished in a grey galvanized appearance. The zinc coating is the corrosion protection, so no paint is required. If you do want it painted to match, galvanized steel needs an etching primer first.
