DEI Power has spent more than a decade helping contractors, engineers, and facility teams source dependable switchgear and power distribution equipment for demanding applications. Operating from a 50,000 sq. ft. facility in Ontario, California, the company combines manufacturing, fulfillment, and engineering support under one roof to improve speed and consistency. That Southern California base supports rapid deployment while giving customers a reliable source for nationwide projects with tight schedules. Over the years, DEI Power has expanded from switchgear manufacturing into a broader distribution and engineering partner, offering custom configurations, documentation support, and domestically manufactured solutions aligned with compliance requirements. The company’s focus remains the same: deliver accurate, code-compliant equipment that helps customers reduce risk, avoid delays, and keep critical operations running.
In power distribution, four common system categories are radial, loop, network, and secondary selective systems. Each serves different reliability, redundancy, and load-management needs. For outdoor equipment distribution projects, the right choice depends on facility criticality, utility coordination, available fault current, and whether the application requires simple service entrance equipment or more advanced switchgear with coordinated protection.
