1-Gang Aluminum Electrical Box

The Killark SWB-5 is a single-gang device box constructed from aluminum. It is rated for hazardous locations and carries CSA and UL listings. The gray enclosure uses lug brackets for mounting and provides two hubs on opposing sides for conduit entry.

22 Cubic Inch Internal Capacity

The decisive specification is the 22 cu in volume, which determines the maximum conductor fill permitted by code. This capacity dictates whether the box can legally accommodate the number and gauge of wires, splices, and devices required for a specific hazardous-location circuit.

Wiring Capacity and Fill Limits

The 22 cu in volume comfortably handles typical single-device installations with a moderate conductor count in hazardous areas. It runs out when the combined volume of conductors, clamps, and the device yoke exceeds the rated allowance, requiring a larger box or an extension ring to remain compliant.
