B-LINE 12126 WPSC – Frequently Asked Questions

1) Can the B-Line 12126 WPSC junction box be used outdoors?
Yes. The Eaton B-Line 12126 WPSC is a Type 3/3R enclosure, so it is built for outdoor use against rain, sleet and windblown dust. It uses an oil-resistant gasket and gasketed screws on a flanged screw cover to keep water out of the wiring space. It is UL 50 listed.
2) What are the actual box dimensions of the B-Line 12126 WPSC enclosure?
12 inches high by 12 inches wide with a 6 inch depth. That 6 inch depth is what decides whether your device, terminal blocks or wire bending space will fit, so check the deepest component before ordering. The box weighs 10.6 lb empty.
3) How does this B-Line WPSC box mount to a wall or strut?
It surface mounts on external mounting feet, so the fastener holes sit outside the enclosure body and you never breach the sealed wiring space to hang it. That keeps the Type 3 rating intact and lets you bolt it to a wall, backboard or strut without drilling through the back panel.
4) Is the 12126 WPSC a hinged door box or a screw cover?
Screw cover, not hinged. The flanged cover comes off completely with gasketed screws. That is fine for a junction or pull box you open rarely, but if your crew needs frequent access to the enclosed equipment, a hinged-door enclosure is the easier choice on the job.
5) Is this junction box steel or stainless, and how is it finished?
Carbon steel at 16 gauge, painted ANSI 61 grey. Carbon steel suits general outdoor and industrial work but it is not the choice for washdown, coastal salt or chemical exposure; specify a stainless or non-metallic Type 4X enclosure for those. Made in the US.
6) Does the B-Line 12126 WPSC come with conduit knockouts?
It ships as a sealed enclosure body with a gasketed screw cover, so conduit entries are field drilled where you need them. Use watertight hub fittings on every penetration, otherwise you give up the Type 3/3R rating you paid for. The 16 gauge carbon steel walls take a standard knockout punch.
7) Will a NEMA 3 box work in a dusty plant interior as well as outside?
Yes. The 12126 WPSC carries NEMA 3 and 12 protection, so it covers outdoor rain and windblown dust plus indoor Type 12 duty against falling dirt, circulating dust, lint and dripping non-corrosive liquids. That makes it a single part number you can standardize on for both yard and plant floor junction points.
8) What is the exact part number to order this 12 x 12 x 6 B-Line weatherproof box?
Order Eaton B-Line part number 12126 WPSC. The number reads as the size first: 12 inch height, 12 inch width, 6 inch depth, followed by the WPSC screw cover enclosure designation.
