Appleton GUALB-100 Hazardous Location Junction Box

Product Description

The APPLETON GUALB-100 is a hazardous location junction box fitted with a 1-inch conduit hub, designed for use in classified environments where ignition-proof and explosion-resistant enclosures are required. Electricians and industrial maintenance technicians install this type of enclosure to house wire connections and splices in areas exposed to flammable gases, vapors, or combustible dust. The 1-inch hub accommodates standard rigid or IMC conduit entries, making it compatible with common industrial conduit systems. This unit is part of Appleton's OZ-G product line, which is engineered for demanding classified-location applications.

This junction box is suited for use in industrial and commercial facilities where National Electrical Code hazardous location requirements apply, including petrochemical plants, refineries, grain handling facilities, wastewater treatment plants, and similar environments. It is installed by licensed electricians working under NEC Article 500 classifications. The 1-inch hub size is a common specification for branch circuit and equipment wiring runs in these settings.
