FAQs
The GUB11031 1 20 is designed to mate with the GUB01 basic housing, providing a mounting interface that aligns with standard meter plates. Begin by confirming conduit routing via the top entry, secure the base to a compliant enclosure or mounting plate, and attach meters to the supplied mounting plate. Verify sealing gaskets and conduct wiring per NEC guidelines to ensure a compliant, leak‑proof installation.
This instrument housing is certified for hazardous/classified locations with NEC/CEC IEC standards, and carries UL‑listed explosion‑proof certification. It also provides NEMA ratings 3, 7, 9, and 12, covering weather resistance, chemical exposure, and heavy‑duty ingress protection. Together, these credentials simplify permit processes and support reliable operation in demanding industrial environments.
Yes. The GUB11031 1 20 features a top conduit opening designed for 3/4" trade‑size conduits, enabling streamlined wiring with minimal bending and reduced risk of moisture ingress. This arrangement is particularly advantageous in tight electrical rooms or overhead installations where conduit routing must be clean and accessible for maintenance.
The enclosure includes a mounting plate for standard meters and is used with GUB01 basic housing, offering a scalable solution for metering deployments. It supports common meter interfaces in hazardous locations, enabling straightforward upgrades or replacements without redesigning the enclosure system.
The GUB11031 1 20 integrates robust materials (Feraloy iron alloy), certified safety ratings, and installation efficiency features that reduce field downtime and maintenance frequency. Although initial costs are higher than non‑explosionproof housings, long‑term ROI improves through lower risk of contamination or corrosion, faster service turns, and streamlined regulatory approvals.
