B-LINE 12126 RTSCGV – Frequently Asked Questions

1) Can the B-Line 12126 RTSCGV junction box be mounted outdoors?
Yes, for outdoor use where falling rain is the concern. The 12126 RTSCGV is a NEMA 3R enclosure with a rainhood over the cover, built from galvanized steel. NEMA 3R protects against rain, sleet and snow but is not a washdown or hosedown rating, so if the location sees direct spray, pressure washing or windblown dust, step up to a 4 or 4X enclosure instead.
2) What are the box dimensions on the B-Line 12126 RTSCGV enclosure?
12 inches high, 12 inches wide and 6 inches deep, which is where the 12126 designation comes from. That 6 inch depth is what decides whether your gutter taps, splices or a small terminal block will actually sit inside with the cover on, so check your deepest device before ordering.
3) Does this B-Line screw cover box come with conduit knockouts already punched?
There are 5 knockouts in the bottom of the enclosure and no others. The top, sides and back come blank, which is deliberate on a 3R box, entries in the top would defeat the rain rating. If you need side or top entry you will have to punch it yourself and seal it with a rated hub or fitting.
4) How does the B-Line 12126 RTSCGV attach to a wall, and do I need a mounting kit?
It surface mounts through embossed thru holes formed into the back of the enclosure, so no external mounting feet or panel adapter kit is needed. Fasteners and anchors are not part of the box, pick those to suit your substrate. Plan for roughly 10 pounds of empty enclosure before conductors.
5) Is a screw cover enclosure the right choice, or should I get a hinged door box?
A screw cover box like the 12126 RTSCGV suits an opening you rarely go back into, pull points, splice boxes, gutter taps. The cover comes fully off with plated screws, so on a wall mount you are holding a 12 by 12 panel while you work. If technicians will open it regularly for testing or resets, a hinged cover version is the easier service choice.
6) Does the B-Line 12126 RTSCGV meet spec for a UL listed enclosure on a submittal?
The enclosure is built to UL 50, the standard covering enclosures for electrical equipment, and that is the citation to put on your submittal alongside the NEMA 3R type rating. It is also made in the US, which matters if the project carries domestic sourcing requirements.
7) Which exact B-Line part number do I order for a 12 x 12 x 6 NEMA 3R screw cover box?
Order part number 12126 RTSCGV from Eaton's B-Line series. The number reads as the dimensions first, 12 high by 12 wide by 6 deep, then RTSCGV for the rainhood screw cover galvanized enclosure style. It is a small single door configuration.
