Commercial Metering Switchboards

A utility switchboard is a power distribution assembly built to utility company specifications, used at the point where utility power enters a facility. It typically includes metering, main disconnect, and overcurrent protection. Units like the Meter Main NEMA 1/3R are designed and EUSERC approved to meet specific utility standards, ensuring seamless interconnection with the utility grid.

DEI Power's Meter Main NEMA 1/3R is available in a wide range of amperage options including 400A, 600A, 800A, 1000A, 1200A, 1600A, 2000A, 2500A, 3000A, and 4000A, making it suitable for small commercial facilities as well as large industrial and utility applications requiring very high-capacity power distribution.

The Meter Main NEMA 1/3R supports multiple voltage configurations including 120/240V, 240V, 208Y/120V, 240/120V, 480V, 480Y/277V, and 415/240V. This broad range of voltage options ensures compatibility with virtually any commercial, industrial, or utility power system in the United States.

NEMA 1 enclosures are designed for indoor use, providing basic protection against dust and contact with energized parts. NEMA 3R enclosures are built for outdoor or exposed environments, offering additional protection against rain, sleet, and external ice formation. DEI Power's Meter Main is available in both ratings, allowing installation flexibility across indoor and outdoor applications.

Yes. DEI Power's commercial metering switchboards meet UBC, CBC, and IBC requirements for all seismic zones. This compliance is critical for installations in earthquake-prone regions, particularly in California and other western states, ensuring that the switchgear remains structurally sound and operationally safe during and after seismic events.
