Steel Interior Panel for Component Mounting

The HOFFMAN A20P20 interior panel provides a steel mounting surface inside compatible enclosures. It is designed for electrical professionals who need to organise components within NEMA-rated junction boxes or wall-mount enclosures. The panel features a white finish and fits enclosures that accept this specific accessory.

Thermal and Power Characteristics in Use

As a passive steel panel, the unit generates no heat and draws no power during operation. It produces no audible noise because it contains no moving parts or active electronics. Thermal management depends entirely on the enclosure design and the components mounted to the panel surface.

Upgrade Path and Compatibility Limits

This panel replaces a missing or damaged interior panel in supported NEMA 12, 4, and 4X enclosures. The upgrade is worthwhile when the existing enclosure lacks a mounting surface or when the original panel is corroded. It is not suitable for enclosures outside the listed NEMA ratings or for applications requiring a different gauge thickness.

Questions about this item

How do I mount the 12-gang interior panel inside a NEMA 12 enclosure?

Align the panel with the enclosure's pre-drilled mounting holes and secure it with the supplied screws; the step often missed is tightening all fasteners evenly to keep the 17.00-inch steel panel flat.

Will the white finish on this steel panel need repainting or corrosion protection over time?

The factory white finish is durable for indoor NEMA 12, 4 and 4X environments; inspect annually for scratches and touch up any bare metal to prevent rust.

What load limit should I watch for when filling all 12 gangs with components?

The 12-gauge steel panel supports typical component densities; the first limit under sustained use is screw-thread stripping if mounting hardware is over-torqued.
