A74BP24

Overview

The Hoffman A74BP24 is a back panel designed for use with specific NEMA-rated enclosures. It provides a mounting surface for internal components and facilitates cable entry through pre-drilled knockout patterns. Constructed from steel, this component ensures structural integrity and proper grounding continuity within the assembly. The panel is engineered to fit precisely into corresponding enclosure frames, maintaining the environmental protection rating of the complete unit when installed correctly.

Feature Summary

• Provides standardized mounting surface for internal electrical components
• Includes pre-formed knockout patterns for cable and conduit entry
• Ensures continuous grounding path between enclosure frame and door

Applications

• Industrial control panels requiring NEMA 1 or 3R protection
• Electrical distribution boards in commercial buildings
• Machine control cabinets in manufacturing environments

Procurement Notes

Verify that the target enclosure model number matches the specifications for the A74BP24 back panel. Confirm material thickness and finish requirements align with project standards. Ensure compatibility with existing knockouts and mounting hole patterns before ordering. Check for any regional compliance certifications if applicable to the installation site.

Selection Notes

Select this back panel only when replacing a damaged unit or building a custom enclosure system where the original Hoffman A74BP24 specification is required. Consider the overall enclosure dimensions and internal layout needs. Evaluate whether standard or specialized knockout configurations are necessary for the intended wiring scheme.

Part Context

This part belongs to the Hoffman Enclosures product line, which manufactures industrial-grade metal enclosures and accessories. The A74BP24 serves as a critical internal component for assembling complete NEMA-rated protective housings. It is typically sold separately from the main enclosure body and door assemblies.

Replacement Considerations

Direct replacement requires matching the original enclosure series. Generic back panels may not align with factory-drilled holes or grounding points. Verify dimensional tolerances to ensure proper fit without modification.
