B-Line Eaton series Type 3/3R junction boxes, 30" height, 12" length, 24" width, 3R, Screw cover, RTSC enclosure, Surface mounted, Medium single door

Yes. The Eaton B-Line 302412 RTSC enclosure carries a NEMA 3R rating, so it is built for outdoor use against falling rain, sleet and external ice formation. It also includes a rain hood over the cover seam and plated screws to slow corrosion at the fasteners. NEMA 3R is not a washdown or hosedown rating, so if the box will see direct pressure spray or heavy dust, step up to a Type 4 or 12 enclosure instead.

It measures 30 inches high, 24 inches wide and 12 inches deep, which is the usable footprint you need to check against your wall space and conduit runs. It weighs 63.4 lb empty, so plan mounting anchors and a second set of hands for the hang.

The 302412 RTSC is a surface mount enclosure with embossed thru holes in the back panel, so it bolts flat to a wall or structural surface using your own anchors sized to the substrate. The embossed holes keep the fastener heads off the mounting surface and help maintain the 3R seal around the back. Anchors and bolts are not part of the box, so pick them for the wall and for the 63.4 lb empty weight plus whatever you install inside.

There are 9 knockouts in the bottom of the box and none elsewhere. That suits conduit entering from below, which is the normal arrangement for a 3R outdoor box since top penetrations invite water. If you need side or back entry you will be punching your own holes in the 14 gauge carbon steel and using a rated hub or fitting to keep the 3R rating intact.

Screw cover. The 302412 RTSC uses a flanged cover fastened with plated screws rather than a hinged, latched door. That is fine for a junction or pull box you open rarely, but if the box houses equipment needing frequent access, a hinged-door enclosure saves you handling loose screws on a ladder every time.

The body is 14 gauge carbon steel with a painted finish in ANSI 61 grey, the standard industrial grey that matches most switchgear and control equipment already on site. Painted carbon steel is right for general outdoor and industrial use; for coastal, chemical or washdown areas, specify stainless or a non-metallic enclosure instead.

Order Eaton B-Line model 302412 RTSC. The number reads directly off the size: 30 inch height, 24 inch width, 12 inch depth, RTSC for the screw cover rainproof enclosure. It ships as a single configuration, so there is no finish or cover option to specify.

No panel is included. The 302412 RTSC is supplied as the enclosure body and screw cover only, and it is sold as a junction and pull box rather than a component housing. If you intend to mount terminal blocks, breakers or a drive inside, order a subpanel sized to the 30 x 24 opening separately, along with the mounting studs or clips that suit it.
