NEMA 1 Carbon Steel Enclosure

This Hoffman wall-mount electrical box is built from carbon steel with an ANSI 61 polyester powder finish in gray. It provides a NEMA 1 rated enclosure for indoor electrical wiring and junction applications. The screw-on solid cover uses screw latches for secure closure. Mounting holes allow direct wall installation.

Indoor Wiring Installations Only

The unit suits electricians and contractors who need a UL-listed, CSA-certified enclosure for protected indoor locations. It is not intended for outdoor use or areas where water, oil or dust ingress protection is required. Buyers needing NEMA 3R, 4, 4X or 12 ratings should select a different enclosure series.

18.0 in H x 12.0 in W x 6.0 in D Interior

The enclosure measures 18.0 inches high, 12.0 inches wide and 6.0 inches deep, defining the maximum space available for terminal blocks, splices or small control devices. This internal volume is the primary factor when deciding whether the box accommodates your specific wiring layout.

Questions about this item

How can I confirm the enclosure meets its NEMA 1 and IP30 ratings after mounting it?

Verify the screw-on solid cover sits flush with the gasket, all mounting screws are tightened to the recommended torque, and no gaps remain around the 18.0 in height by 12.0 in width opening.

What hardware comes with the carbon-steel box and what must I supply for a wall installation?

The unit includes the gray ANSI 61 polyester-powder-coated enclosure with screw-latch cover and pre-drilled mounting holes; you must provide wall anchors, screws and any internal DIN rail or panel separately.

Which metal gauge should I select for a 12.0 in wide by 6.0 in deep enclosure in this series?

The A90P1 series uses 12/14/16 ga carbon steel construction across all sizes, so the gauge is fixed for the 18.0 in high model and does not vary by capacity.
