B-Line Eaton series fiberglass accessories, 4X, White powder coated, Steel, Fiberglass accessories, Fits 30" X 20" enclosures, Back panel, 12 gauge

The AW3020P back panel is sized for 30 x 20 inch enclosures in the Eaton B-Line fiberglass series. The panel itself measures 27 inches high by 17 inches wide, which is the usual inset from the enclosure's nominal outside dimensions so it clears the internal mounting studs. If your box is a different nominal size, you need the matching panel for that size, not this one.

No. The AW3020P is an internal back panel that mounts on the studs inside the box, so nothing passes through the enclosure wall and the seal is untouched. It is catalogued at NEMA 4X along with the enclosure series it serves and carries CSA C22.2 certification. Your rating stays intact as long as you do not drill the enclosure itself.

Steel, 12 gauge, with a white powder coated finish. It is an accessory for fiberglass enclosures, but the panel itself is metal, so it gives you a solid surface for drilling and tapping to mount DIN rail, terminal blocks, contactors or a small drive. The white coating makes it easier to read legends and see small wire markings inside the box.

You get a 27 by 17 inch flat steel surface, with 17 inches given as the panel depth dimension as well. Lay out your DIN rail runs and wire duct against those numbers before ordering, because on a 30 x 20 box the panel is smaller than the door opening and a component layout drawn to the enclosure's nominal size will not fit.

Panels like the AW3020P are ordered as a separate accessory item under the Eaton B-Line fiberglass accessories line. If you are quoting a 30 x 20 fiberglass box for a wash-down or corrosive area, add the panel as its own line or the box arrives with nothing to mount to.

The panel is powder coated steel serving NEMA 4X rated fiberglass enclosures, which is the rating used for hose-down and corrosion-prone locations. Inside a sealed 4X box the panel is protected from the environment. Where the interior itself sees chemical carryover or condensation, a stainless or non-metallic panel is the better call, since coated steel will rust anywhere the coating gets cut or drilled.
