The Hoffman Enclosures A8R86NK is a commercial-grade pull box enclosure constructed from carbon steel with a polyester powder-painted galvanized finish. It features an ANSI 61 gray color and measures 8 inches in height, 8 inches in width, and 6 inches in depth. The unit utilizes a screw-on closure method for the solid cover. It carries NEMA 3R and IP32 ratings, making it suitable for outdoor applications requiring protection against falling rain and sleet.
Verify that the specific project requirements align with the NEMA 3R rating, as this model is not designed for submersion or high-pressure washdown conditions. Confirm that the 8x8x6 inch internal volume meets the wire fill capacity needs for the intended circuitry. Ensure mounting surfaces are compatible with the enclosure's wall-mount design and weight specifications.
Select this model when a compact, weather-resistant solution is needed for light-duty outdoor electrical work. It is appropriate for environments where protection from rain and falling debris is required but does not demand the higher ingress protection of NEMA 4X. Consider material thickness and finish durability if the installation site has specific corrosive exposure risks beyond standard atmospheric conditions.
This component belongs to the nVent Hoffman commercial enclosure line, which focuses on cost-effective solutions for general-purpose electrical distribution. The A8 series typically denotes standard steel enclosures with screw covers, distinguishing them from hinged-door models. These units are widely used in residential and light commercial construction for branch circuit management.
Direct substitutes include other NEMA 3R steel pull boxes of identical dimensions, such as those from Square D or Eaton. When replacing, ensure the new unit maintains the same 16-gauge material thickness and screw-cover configuration to preserve mounting hole alignment and sealing characteristics.

Understand tactile switches, PCB and keyboard differences, four-pin wiring, debounce, force, travel and replacement checks for reliable control inputs.
