A6660RT

Overview

The Hoffman Enclosures A6660RT is a NEMA Type 3R wiring trough constructed from 16-gauge steel. It measures 6 inches in width, 6 inches in height, and 60 inches in length. The unit features a slip-on removable cover design for access to internal components. The exterior finish consists of ANSI 61 gray polyester powder paint applied over a pretreated surface to ensure weather resistance against rain, sleet, snow, and humidity. This component is certified under UL 870 and CUL standards for indoor and outdoor installations.

Feature Summary

• Provides protection against environmental elements including rain, sleet, and snow
• Constructed from durable 16-gauge steel with corrosion-resistant coating
• Features a slip-on removable cover for simplified wire management access

Applications

• Outdoor wire and cable distribution protection
• Protection for junctions and terminations in exposed environments
• Indoor/outdoor installations requiring NEMA Type 3R compliance

Procurement Notes

Verify the specific catalog number A6660RT matches the required dimensions and material specifications. Confirm that the slip-on cover style meets installation requirements rather than screw-on variants. Ensure the UL 870 and CUL certifications are valid for the intended jurisdiction. Cross-reference the ANSI 61 gray color code if aesthetic consistency with existing infrastructure is necessary.

Selection Notes

Select this model when NEMA Type 3R protection is mandatory for wiring trough applications. The 6x6x60 inch size accommodates standard cable runs without excessive bending radius constraints. The steel construction offers higher mechanical strength compared to plastic alternatives. Verify site conditions do not require stainless steel or specialized chemical resistance beyond standard polyester powder coating.

Part Context

This part belongs to the nVent Hoffman wiring trough series designed for electrical infrastructure management. It serves as a protective channel for organizing and shielding cables from physical damage and environmental exposure. The Type 3R rating distinguishes it from indoor-only enclosures, making it suitable for exterior building mounting or covered outdoor areas where precipitation is a factor.

Replacement Considerations

Direct substitutes include other manufacturers' NEMA Type 3R wiring troughs with identical 6x6x60 inch dimensions. Verify compatibility with existing mounting hardware and conduit entries. Note that some competitors may offer screw-on covers instead of slip-on designs, which affects maintenance access procedures.
