B-Line Eaton series wall mounted panel enclosure, 30" height, 12" length, 24" width, 4, Hinged cover, 4 enclosure, Wall mount, Medium single door, Ex

It carries a NEMA 4 rating, which covers outdoor use and hosedown/washdown locations: windblown dust, rain, splashing water, and direct hose-directed water. The seal comes from a seamless poured in-place gasket, and the door is pulled down with stainless steel clamps so the gasket compresses evenly. It is not rated for corrosive washdown chemicals, since the body is painted carbon steel rather than stainless.

External mounting feet are part of the enclosure, so it bolts straight to the wall or to Unistrut without a separate bracket kit. The feet sit outside the box, which means no fastener penetrates the sealed enclosure body, and the NEMA 4 seal stays intact. Plan the anchors for the load: the unit weighs 65 lb empty, before any panel, breakers, or wiring go in.

No subpanel is included with the 302412-4. What you get is the enclosure itself: 14 gauge carbon steel body, hinged gasketed door, stainless clamps, and external mounting feet. If you are mounting a panelboard, terminal blocks, or DIN rail, order the matching back panel separately and budget for its fasteners.

It is built to UL 50, the standard for enclosures for electrical equipment, and country of origin is the United States. That combination is what most government, healthcare, and education procurement specs are looking for when a submittal calls out a UL 50 enclosure with domestic origin.

Yes. The 302412-4 has a padlock provision on the hinged cover, so a standard shackle padlock or a lockout hasp secures the door without adding hardware. There is no keyed handle or three-point latch on it; closure is by stainless steel door clamps, and the padlock is what keeps unauthorized hands out.

Body and door are 14 gauge carbon steel, painted ANSI 61 grey, the standard grey used across industrial control gear so it matches existing panels in a plant or mechanical room. 14 gauge is the usual commercial weight for a box this size, stiff enough that the door stays flat against the gasket and will not oil-can when you hang device plates or a subpanel inside.

Yes. NEMA 4 enclosures like the 302412-4 ship without knockouts, because any factory opening would break the watertight seal. You drill or punch where you need it and use watertight hub fittings rated for NEMA 4 so the rating is preserved after install. Lay out your entries before you set the box on the wall.

Check your swing clearance, not just the footprint. The box is 12 inches deep on the wall and 24 inches wide, and the cover is hinged on one side, so you need roughly the full 24 inch width as clear door swing in front of it plus working space to reach inside. The mounting feet stand the body slightly off the wall for drainage and chase clearance. In a narrow aisle, a shallower enclosure or one with the hinge on the opposite side is the better call.
