A20P16C

Overview

The Hoffman A20P16C is a composite backplate designed for 20 x 16 inch junction boxes and UL/NEMA wall-mount enclosures. It measures 17.00 x 13.00 inches with a thickness of 0.19 to 0.60 inches. Constructed from reinforced phenolic material, it provides NEMA 12 and NEMA 17 ratings for dust and drip protection. The panel features a light brown color and solid type construction, serving as a durable mounting surface for electrical components within industrial enclosure systems.

Feature Summary

• Constructed from reinforced phenolic material for durability
• Provides NEMA 12 and NEMA 17 environmental protection ratings
• Designed specifically for 20 x 16 inch enclosure compatibility

Applications

• Junction box assembly
• UL/NEMA wall-mount enclosure installation
• Industrial electrical component mounting

Procurement Notes

Verify the specific thickness requirement (0.19 or 0.60 inches) against your design specifications, as sources vary. Confirm that the 17 x 13 inch panel dimensions align with the internal cutout requirements of the 20 x 16 inch enclosure frame. Ensure the reinforced phenolic material meets the necessary dielectric and mechanical standards for the intended application environment.

Selection Notes

Select this panel when a rigid, non-conductive mounting surface is required for NEMA 12 rated enclosures. The reinforced phenolic composition offers superior structural integrity compared to standard plastic alternatives. Consider the specific dimensional tolerance between the 17 x 13 inch panel and the 20 x 16 inch housing to ensure proper fitment without excessive gaps or interference.

Part Context

This component belongs to the Hoffman Enclosures composite panel series, which provides standardized replacement and accessory parts for industrial electrical housings. The A20P16C model specifically addresses the need for robust backplates in environments requiring dust and drip resistance. It complements the broader nVent Hoffman product line by offering specialized materials for enhanced enclosure performance.

Replacement Considerations

Cross-reference part number 65640 as an alternative identifier. Verify dimensional compatibility before substitution, as phenolic laminate thickness variations may affect mounting hardware alignment. Ensure the replacement maintains the original NEMA 12 rating requirements.
