  • Captive plated screws simplify cover removal

Compact Galvanised Steel Enclosure

The Wiegmann SC040404GNK is a 4×4×4 inch NEMA 1 rated box built from 16 gauge galvanised steel. It suits indoor installations where a small, wall mounted junction or pull box is required. The solid cover secures with captive plated steel screws that stay with the lid. This unit is CSA certified and cULus listed for code compliant work.

Indoor Thermal Performance

Galvanised steel dissipates heat from enclosed breakers or terminals without forced airflow in typical indoor ambient conditions. The screw on cover maintains a tight seal that limits dust ingress while allowing easy access for inspection. No fans or vents are present so acoustic output is zero. Power draw depends entirely on the devices you install inside the enclosure.

Upgrade From Plastic Or Larger Boxes

This enclosure replaces non metallic boxes when metallic grounding paths or higher mechanical protection are specified. It also serves as a space saving alternative to larger steel cabinets where only a few connections are needed. The jump is worth it when the project demands a listed metallic enclosure with a compact 4 inch footprint and a usable opening depth of 3.88 inches.

Questions about this item

How do I mount the SC040404GNK enclosure and what is the common mistake?

Use the wall-mounting holes on the 16 ga galvanised steel body; the step often missed is tightening the plated steel captive screws evenly so the solid cover seals to the NEMA 1 rating.

What maintenance or replacement will the SC040404GNK need over time?

The plated steel captive screws and solid cover gasket should be inspected periodically; replace screws if threads strip or corrosion appears, and swap the gasket if compression set prevents a NEMA 1 seal.

What is the first limit reached when the SC040404GNK is used continuously in a warm cabinet?

The usable opening depth of 3.88 in restricts component height and airflow, so thermal buildup inside the 4 in cube becomes the limiting factor before the 16 ga steel or CSA/cULus ratings are stressed.
