A20P16J

Overview

The Hoffman A20P16J is a conductive enclosure panel designed for junction boxes. It measures 18-3/4 inches in length and 14.88 inches in width, corresponding to a nominal 20x16 inch box size. Constructed from 14-gauge mild steel, the panel features a white polyester powder-coated finish for corrosion resistance. The unit weighs approximately 6.34 pounds and is suitable for use with NEMA 4, 4X, 12, and 13 rated enclosures.

Feature Summary

• Conductive material composition for grounding applications
• White polyester powder coating for corrosion protection
• Compatible with standard 20x16 inch junction box frames

Applications

• NEMA 4 and 4X junction box assemblies
• NEMA 12 and 13 industrial enclosures
• Conductive backplate replacement for existing housings

Procurement Notes

Verify exact dimensional requirements against the target enclosure model before procurement. Confirm that the conductive coating meets specific grounding or corrosion resistance standards required by the installation environment. Ensure compatibility with mounting hardware provided with the associated junction box system.

Selection Notes

Select this part when a conductive mild steel panel is required for a 20x16 inch junction box application. The white polyester finish offers standard environmental protection. Consider alternative materials such as stainless steel or aluminum if higher corrosion resistance or non-conductive properties are necessary for the specific operational context.

Part Context

This component belongs to the Hoffman Enclosures line of accessories for industrial junction boxes. It serves as a cover or backplate for metal enclosures requiring conductive surfaces. The product is manufactured by nVent Hoffman, specializing in protective housing solutions for electrical components in demanding environments.

Replacement Considerations

Direct substitutes include other manufacturers' panels sized for 20x16 inch boxes. Verify gauge thickness and hole patterns match the original assembly. Non-conductive alternatives like polycarbonate may be used if grounding is not required.
