Material strength and durable protection drive long-term reliability in tough environments. The GUP214 uses a Feraloy iron alloy body, delivering superior resistance to corrosion and impact, which translates to reduced replacement cycles and lower lifecycle costs for ongoing hazardous-location projects. This translates to a measurable business impact: less downtime due to enclosure failures and more consistent operation in refinery, chemical processing, and mining facilities where exposure to harsh chemicals and physical wear is common. The enclosure’s configuration matters: with four back hubs plus additional top, bottom, and side hubs, wiring layouts become flexible and installation faster, minimizing field modifications and commissioning time for multi-conduit installations. In practice, that means engineers can route cables cleanly in tight spaces without compromising sealing integrity or safety, enabling compliant installations in compact control rooms and outdoor installations.

FAQs
GUP214 is designed for NEC/CEC compliant hazardous locations with Class I, II, and III ratings and UL certification for explosion‑proof service. Its hub configuration (4 back hubs plus top, bottom, and side hubs) supports flexible conduit layouts, reducing field modifications while maintaining enclosure integrity and gasketing performance in demanding environments.
The enclosure provides four 3/4 inch back hubs, two 3/4 inch top hubs, two bottom hubs, and one 3/4 inch side hub. This enables back-to-back and multi-conduit installations, simplifies cable management, and minimizes the need for additional fittings. The result is quicker installations and cleaner wiring in limited spaces without sacrificing protection.
Yes, the GUP214 is UL certified for explosion-proof service and NEC/CEC compliant. It carries hazardous area ratings including Class I, Division 1 and 2, Class II Division 1 and 2, and Class III, with area classification for Hazardous/Classified Locations. These certifications support regulatory compliance and safer operation in demanding industrial settings.
Resources include the IF 1497 installation sheet, the Crouse-Hinds GUP catalog page, and the Eaton specification sheet for GUP214. These materials provide wiring guidance, mounting recommendations, and verified installation practices to speed up field work and ensure correct enclosure use in hazardous locations.
The GUP214 combines certified safety, robust material performance, and flexible hub options, which lowers risk of noncompliance and field rework. Its compact footprint supports space-constrained installations, while the durable Feraloy iron alloy body extends service life, reducing maintenance costs and downtime in challenging environments such as chemical plants, oil & gas facilities, and mining operations.
