This policy outlines customer responsibilities and design requirements for meter rooms housing customer-owned and maintained meter service equipment (switchboards, meter sockets, CT cabinets).

An internal electrical room adjacent to the building's outer wall (with the switchgear adjacent to the outer wall) is allowed with written approval from NVE. The meter room must be illuminated and can be used for communication equipment.

Jul 9, 2024 · The NEC mandates specific requirements for electric service and meter installations to ensure safety and reliability. These include proper grounding, clearances, and accessibility.
