Electrical enclosure for indoor wiring

The HOFFMAN ASE4X4X4NK is a carbon-steel electrical enclosure rated NEMA Type 1 and IP30 for indoor use. It measures four inches high, four inches wide and four inches deep with a solid screw-on cover. The box carries cUL listing per CSA C22.2 No 40 and UL 50, 50E listing with file number E27525.

Captive screws simplify cover handling

The cover uses captive screws that stay attached to the enclosure so they cannot be lost during installation or maintenance. Mounting holes are provided for direct wall attachment. A powder-coated grey finish protects the 12/14/16 gauge steel from corrosion in dry indoor environments.

Suited for basic indoor junction boxes

Installers running indoor branch circuits or low-voltage wiring in dry locations will find this enclosure meets code requirements. It is not intended for outdoor, wet or dusty locations that demand a higher NEMA or IP rating, nor for applications requiring a transparent cover or larger internal volume.

Questions about this item

Will the captive screws on the cover need replacement after repeated opening?

Captive screws are built into the cover and stay attached, so they do not require separate replacement.

What limits continuous use of this carbon-steel enclosure?

The NEMA Type 1 and IP30 ratings restrict it to indoor, non-hazardous locations.

How much heat builds up inside a 4 in by 4 in box under all-day load?

Powder-coated carbon steel dissipates heat passively; no active cooling is included.
