FAQs
The GUB3191 1 20 instrument housing is designed to pair with the GUB03 basic housing for metering equipment in hazardous locations. It adds a mounting plate, top conduit entry, and Class I/II/III, NEC/CEC IEC approvals, enabling a modular upgrade path without custom fabrication. Ensure the mating flanges and mounting pattern align with the GUB03 base when planning your installation.
The GUB3191 1 20 is rated for Hazardous/Classified Locations with NEC Class I, Division 1 and 2, Class II Division 1 and 2, and Class III, along with NEMA ratings 3, 7, 9, and 12. It also supports NEC/CEC IEC standards compliance, ensuring electrical safety, correct protection against ignition sources, and suitability for metering equipment in demanding environments.
Yes. The GUB3191 1 20 instrument housing features a top conduit opening, simplifying wiring in installations with limited space or overhead routing. This configuration reduces conduit runs and elbow fittings, accelerating installation while maintaining enclosure integrity and hazardous-location protection for metering equipment.
Key considerations include verifying the mounting plate compatibility with standard meters, confirming 3/4" trade size fittings, and ensuring proper sealing for hazardous locations. Follow the IF 1112 GUB Instrument Housings instructions for step-by-step setup, including grounding, torque recommendations, and wiring within the enclosure to maintain safety and compliance.
The GUB3191 delivers long-term value through rugged material (Feraloy iron alloy), high NEMA/IEC ratings, and modular compatibility with GUB03. This reduces maintenance frequency, minimizes redesign costs, shortens installation cycles, and lowers total cost of ownership in harsh industrial environments such as refineries, chemical plants, and mining facilities.
