Yes. It is designed for Ordinary/Non-Hazardous locations and complies with NEC/CEC standards. Canadian certification is supported via UL-linked certification pages, enabling cross-border use in North American facilities and other regions with similar requirements. Welded steel construction also enhances durability in challenging environments.
Cite NEC/CEC compliance for standard electrical installations, Ordinary/Non-Hazardous area classification for non-hazardous environments, and Canadian certification as reflected in UL documentation. These certifications help ensure regulatory alignment, simplify inspections, and support cross-border project deployments.
The welded steel construction provides robust long-term performance with minimal field maintenance. The enclosure’s standard dimensions and knockouts support future wiring upgrades without enclosure replacement. Regular inspections should focus on gasket integrity (if used), mounting security, and knockouts for any signs of deformation or corrosion in demanding environments.
