B-LINE 12124 RTSCGV NK – Frequently Asked Questions

1) Can the B-Line 12124 RTSCGV NK junction box be mounted outdoors?
Yes. The 12124 RTSCGV NK is a NEMA 3R enclosure, so it is built for outdoor use where falling rain, sleet and external ice formation are the concern. It has a rainhood over the cover seam and galvanized steel construction. NEMA 3R is not a washdown or hosedown rating, so keep it off surfaces that get pressure-sprayed.
2) What are the actual box dimensions on the B-Line 12124 RTSCGV NK enclosure?
12 inches height, 12 inches width and 4 inches depth. That 4 inch depth is what usually decides it: with device rails, terminal blocks or wire bending space, 4 inches is fine for splices and small terminations but tight for stacked components. It weighs 8.3 lb empty.
3) Does this Eaton B-Line 12x12x4 enclosure come with knockouts?
No knockouts. The 12124 RTSCGV NK is the NK (no knockout) version, so every conduit entry gets punched or hole-sawed in the field. That lets you place entries where your run lands, but plan on a step bit or knockout punch and the right rain-tight fittings on top and side entries to hold the 3R rating.
4) Is this B-Line junction box UL listed for a spec submittal?
It carries UL 50, the standard covering enclosures for electrical equipment. Paired with the NEMA 3R rating, that is normally what an inspector or spec reviewer wants to see for an outdoor surface-mounted junction or pull box. Made in the US.
5) How does the cover open on the B-Line 12124 RTSCGV NK, and is it hinged?
It is a screw cover, not hinged. The cover lifts off entirely once the plated screws are backed out, which is fine for a junction or pull box you rarely open. If you need repeated access or one-hand entry, look for a hinged-door 3R enclosure instead.
6) How is this galvanized junction box mounted to a wall?
Surface mount, using embossed thru holes formed into the back of the box. The embossing keeps the mounting holes off the sealing plane so water does not track in at the fasteners. Mounting hardware and anchors are sized to your substrate and are not part of the box.
7) What gauge steel is the Eaton B-Line RTSCGV NK enclosure, and will it need painting?
16 gauge galvanized steel, supplied unfinished in a grey galvanized appearance. There is no paint system on it, so it goes in as-is for utility, mechanical yard and service equipment locations. If the spec calls for a painted finish, this is not the box.
8) What part number do I order for the 12 x 12 x 4 NEMA 3R screw cover box with no knockouts?
The Eaton B-Line catalog number is 12124 RTSCGV NK. The number reads out as the size and build: 12 x 12 x 4, rain-tight screw cover, galvanized, no knockout. Ordering the same size without the NK suffix gets you a knockout version, which is a different box.
9) Is a NEMA 3R box like this acceptable for a washdown or dusty indoor area?
No. A 3R enclosure handles rain, sleet and ice outdoors, but it is not sealed against dust, windblown dust, hosedown or oil. For those conditions you want a NEMA 4, 4X or 12 enclosure. Indoors in a clean dry electrical room, a 3R box works fine, it is just more enclosure than you need.
