B-LINE AW4230P – Frequently Asked Questions
1) Which enclosure size does the B-Line AW4230P mounting panel fit?
The AW4230P steel back panel is built for 42 x 30 inch enclosures, specifically the fiberglass type. It is a flat panel, so it mounts to the standoffs inside the box rather than sitting in a channel. If your enclosure is a different nominal size, the panel will not line up with the mounting studs.
2) What are the actual panel dimensions of the AW4230P so I can lay out my components?
Usable panel size is 38 inches by 26.875 inches, with a stated depth figure of 26.875 inches as well. Lay out breakers, terminal strips and DIN rail against the 38 x 26.875 face. It is noticeably smaller than the 42 x 30 enclosure it goes in, which is normal for a back panel since it has to clear the enclosure's interior flange and mounting hardware.
3) Will this flat panel work in a metal NEMA enclosure, or only fiberglass?
This one is specified as the flat panel for fiberglass enclosures at the 42 x 30 size. Fiberglass boxes use molded-in or bonded standoffs on a different pattern than a typical steel wall-mount box, so a panel cut for one is not a drop-in for the other. If your box is painted steel or stainless, order the panel that the enclosure manufacturer lists for that specific box.
4) I'm replacing a damaged back panel in an existing 42 x 30 fiberglass enclosure. Is this the right part number?
For a 42 x 30 fiberglass enclosure, AW4230P is the Eaton B-Line flat steel panel sized to it, measuring 38 by 26.875 inches. Before ordering, pull the old panel and measure it. If the existing one measures out to those numbers and the stud pattern matches, this replaces it directly.
5) Is the B-Line AW4230P panel steel or aluminum, and how is it finished?
Steel, finished in white powder coat. The white face makes it easier to see wire markings and component labels inside a dark enclosure, and steel lets you drill and tap directly for component mounting. If you need a non-ferrous or unpainted conductive panel for grounding a component directly to the panel face, this painted one is not that.
6) Does the AW4230P come with mounting hardware or standoffs?
What you are buying under model AW4230P is the steel back panel itself. Fiberglass enclosures normally ship with their own panel mounting studs and nuts, so plan on using the hardware that came with the box, or sourcing replacement studs separately if the enclosure is being reused and the originals are missing.
7) Is the AW4230P mounting panel NEMA rated?
NEMA is the standard referenced for this B-Line Eaton series panel. Keep in mind the environmental rating of an installation comes from the enclosure and its gasket and latches, not the interior back panel. The panel's job is to give you a rigid, drillable steel mounting surface inside the box.
