B-LINE 36366 RTSC NK – Frequently Asked Questions

1) Can the B-Line 36366 RTSC NK junction box be installed outdoors?
Yes. The 36366 RTSC NK carries a NEMA 3R rating, which covers outdoor use against falling rain, sleet and external ice formation. It ships with a rain hood and a flanged cover to shed water off the opening. It is not a washdown or hosedown enclosure, so for direct spray or dust-tight service you want a Type 4 or 4X box instead.
2) What are the actual box dimensions on the B-Line 36366 screw cover enclosure?
36 inches high by 36 inches wide with a 6 inch depth. That gives a large flat back panel area for terminal blocks or gutter work while keeping the box shallow enough to sit close to the wall on a surface mount.
3) Does this Eaton B-Line enclosure come with knockouts for conduit?
No knockouts. The RTSC NK is a no-knockout box, so every conduit entry gets punched or hole-sawed on site wherever the run lands. That is what you want on a 3R outdoor box, since unused factory knockouts are a water path, but budget the labor and the hole saws.
4) Is the B-Line 36366 RTSC NK enclosure UL listed for a spec job?
It is built to UL 50, the standard for enclosures for electrical equipment. Paired with the NEMA 3R rating, that is normally what a submittal for an outdoor pull or junction box calls for. It is made in the US, which matters where domestic-content language is in the contract.
5) How does this enclosure mount to the wall, and does it need extra brackets?
It is a surface mount box with embossed thru holes in the back, so it bolts straight to a wall or strut without separate mounting feet. The embossed holes stand the fastener area off the back surface, which keeps the seal intact at the mounting points. You supply the anchors suited to your substrate.
6) Is this a hinged door enclosure or a bolt-on cover?
It is a screw cover box, not a hinged-door enclosure. The cover lifts off on plated studs and wing nuts, so you can get the whole face out of the way for pulling and terminating, but you need somewhere to set a 36 by 36 inch cover down while you work. If you need frequent access with the cover captive, specify a hinged-door type instead.
7) How heavy is the 36x36x6 B-Line screw cover box, and is this a one-man install?
104.9 lb. That is a two-person lift and hold at minimum, and on a wall you want the anchors set and a temporary ledger or strut rail under it before you try to line up the holes. Plan hoisting for anything above chest height.
8) Can I use this outdoor screw cover box as a wireway pull box on a long conduit run?
Yes, that is its usual role. With a 36 by 36 inch face and 6 inch depth you get generous bending room for a pull or splice point, and because there are no factory knockouts you place the entries exactly where the run comes in. The full removable screw cover gives you both hands on the pull.
9) Does a back panel come with this B-Line 36366 enclosure?
The 36366 RTSC NK is supplied as the enclosure body and screw cover with plated studs and wing nuts. Any inner back panel, terminal kit, or mounting hardware for the wall is ordered separately.
