HOFFMAN A24P20G Interior Panel

The HOFFMAN A24P20G is a steel interior panel designed for mounting components inside compatible enclosures. It provides twelve gangs for organising electrical devices in industrial or commercial installations. The panel suits electricians and panel builders who need a structured mounting surface within NEMA-rated junction boxes or wall-mount enclosures. It is not for buyers who need a complete enclosure or a panel with a different gang count.

Galvanised Steel Construction

The panel uses galvanised steel for corrosion resistance in demanding environments. This finish protects the panel when installed in NEMA 12, 4 or 4X rated enclosures. No moving parts or active cooling are present so the panel adds no noise or power draw to the installation. Thermal performance depends entirely on the enclosure and the components mounted on the panel.

Twelve Gang Capacity

The panel measures 21.00 inches high by 17.00 inches wide and is built from 12 gauge steel. These dimensions and the twelve gang layout determine whether the panel fits a specific enclosure and accommodates the required number of devices. Verify the enclosure internal dimensions and gang requirement before purchase.

Questions about this item

How do I install the 12-gang steel interior panel into a NEMA 12 enclosure?

Mount the panel using the enclosure's pre-drilled holes and supplied hardware; the step often missed is torquing each screw evenly to prevent the 12-gauge steel from warping.

What maintenance will the galvanized steel panel require over time?

Inspect the galvanized finish annually for white rust or scratches; touch up any damaged areas with cold-galvanizing compound to maintain corrosion resistance inside the junction box.

What is the first limitation when mounting heavy components on the 21.00 by 17.00 inch panel?

The 12-gauge steel thickness sets the load limit; exceeding the enclosure manufacturer's weight rating causes deflection before the panel material itself yields.
