Wiegmann NP2420 Enclosure Back Panel 17x21 in 14 Gauge

Product Description

The WIEGMANN NP2420 is a steel back panel designed for use inside standard electrical enclosures. It provides a rigid, powder-coat-finished mounting surface for terminal blocks, DIN rails, contactors, relays, and other electrical components. Fabricated from 14-gauge steel, the NP2420 measures 17 inches overall width by 21 inches overall height, sized to fit a 24-inch by 20-inch enclosure box. The powder coat finish adds corrosion resistance and a clean surface for labeling or component layout. Electricians and panel builders install this panel during new enclosure builds or when replacing a damaged OEM panel in the field.

This back panel is suited for commercial and industrial electrical enclosure applications where a durable, code-compliant mounting surface is required. It installs inside NEMA-rated enclosures used in control panel fabrication, mechanical rooms, and equipment enclosures. The panel is compatible with multiple Wiegmann enclosure boxes including both hinged and standard configurations across the 24-inch by 20-inch enclosure family. It is appropriate for use in environments requiring NEMA 1, 3R, 4, 4X, or 12 rated enclosures.

Installation Notes

Installation is typically performed by licensed electricians or control panel fabricators. De-energize all circuits and verify zero voltage at the enclosure before servicing or installing internal components. Secure the panel using the enclosure manufacturer's specified mounting hardware and verify all component clearances comply with NEC requirements for the enclosure type. Avoid drilling or modifying the panel in ways that compromise the enclosure's NEMA rating.
