B-LINE 16126 RTSC – Frequently Asked Questions

1) Can the Eaton B-Line 16126 RTSC junction box be mounted outdoors?
Yes. The 16126 RTSC carries a NEMA 3R rating and includes a rain hood over the cover, so it is built for outdoor wall mounting where falling rain, sleet and ice are the concern. It is not a washdown or hosedown enclosure, so keep it off applications that need 4 or 4X protection.
2) What are the box dimensions on the B-Line 16126 RTSC enclosure?
It measures 16 inches high, 12 inches wide and 6 inches deep, which is the usable footprint you get for terminal blocks, splices or a small panel. Shipping weight of the box is 12.3 lb.
3) Does this B-Line junction box come with knockouts, or do I have to punch my own?
There are 5 knockouts in the bottom of the box. Top and sides are blank on a 3R enclosure by design, since penetrations above the live parts defeat the rain-tight rating. Any additional entries you make should go in the bottom or lower sides.
4) How does the B-Line 16126 RTSC mount to a wall?
Surface mount, using embossed thru holes in the back of the box. The embossments hold the enclosure off the mounting surface so water drains behind it instead of pooling, which is what you want on an exterior wall. Fasteners and any strut or standoffs are supplied by the installer.
5) Is the cover on the 16126 RTSC hinged or does it screw on?
Screw cover, flanged, with plated screws. You lift the whole cover off to work in the box rather than swinging a door, so allow clearance in front and plan on a driver at every service visit. If you want a hinged door you need a different style enclosure.
6) What gauge steel is this enclosure, and will it hold up outside?
The body is 16 gauge carbon steel with a painted finish in ANSI 61 grey. Carbon steel painted is the standard choice for general outdoor and industrial use. In coastal salt air or a chemical environment, specify stainless or a non-metallic 4X box instead.
7) Does the 16126 RTSC include a back panel for mounting components?
The RTSC is a screw cover junction box, supplied as the box and cover. No sub-panel is called out with it, so if you plan to mount terminal strips, relays or a small controller inside, order a panel separately and size it to the 16 by 12 inch interior.
8) What part number do I order for the 16 x 12 x 6 B-Line 3R screw cover box?
Order Eaton B-Line 16126 RTSC. The number reads as the dimensions: 16 high, 12 wide, 6 deep, with RTSC for the rain-tight screw cover style.
