B-LINE 15124 RTSC – Frequently Asked Questions

1) Can the B-Line 15124 RTSC enclosure be mounted outdoors?
Yes. The Eaton B-Line 15124 RTSC screw cover enclosure carries a NEMA 3R rating, so it is built for outdoor use against falling rain and dripping water, and it includes a rain hood over the cover. It is not a washdown or hose-down box, so keep it out of direct spray and submersion locations.
2) What are the box dimensions on the B-Line 15124 RTSC junction box?
It measures 15 inches high, 12 inches wide and 4 inches deep, which is the usable depth you have for gutter work, terminal blocks or a small device. The 4 inch depth is tight for anything with deep back-mounted components, so check your DIN rail or contactor depth before committing.
3) How does this B-Line enclosure attach to a wall or strut?
It is a surface mount enclosure with embossed thru holes in the back, so it bolts flat to a wall, backer board or strut run. Mounting bolts or anchors are not part of the enclosure, so pick fasteners to suit the substrate. At 9.9 lb empty, a single installer can hang it, but hold it level while you set the anchors.
4) Does the 15124 RTSC come with conduit holes already punched?
There are 5 knockouts in the bottom of the box and no factory openings elsewhere. That suits bottom entry for outdoor work, which is what you want on a 3R box so water is not running into a top penetration. If you need side or back entry you will have to punch it yourself and use a raintight fitting to keep the 3R rating intact.
5) Is a screw cover enclosure the right choice, or do I need a hinged door box?
A screw cover box like the RTSC is for enclosures you open rarely, junction and pull points, splices, gutter taps. The flanged cover comes off completely and you handle loose plated screws on a ladder. If an electrician or technician needs regular access to breakers, relays or terminals, choose a hinged continuous door enclosure instead so the cover stays captive.
6) What gauge steel and finish is the B-Line 15124 RTSC, and will it hold up outdoors?
Body and cover are 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard industrial enclosure color, so it matches gear and panels already on the site. Cover screws are plated to resist rusting in place outdoors. For coastal or chemical exposure where paint will not last, specify a stainless or non-metallic 3R enclosure instead.
7) Is the B-Line 15124 RTSC UL listed for a commercial spec job?
It is built to UL 50, the enclosure standard for electrical equipment, and it is made in the US. That plus the NEMA 3R rating is usually what a spec or inspector is looking for on an outdoor junction or pull box.
