Eaton 3MM320RC Residential Meter Stack - UL Listed

Multiple metering capability is the core feature of the 3MM320RC, enabling measurement of several tenants or circuits from a single outdoor enclosure. This translates to a clear business impact: improved energy visibility, precise allocation for billing, and easier energy-management reporting. In practical terms, developers and building operators deploy this configuration on multi-tenant campuses to drive accurate chargeback and simplified utility administration. The data produced by this stack feeds energy management systems and billing platforms, enabling real-time load visualization and on-demand cost reconciliation. Engineers appreciate the modularity as it accommodates future metering expansions without a full system replacement. Outdoor installation with a weather-resistant enclosure reduces field exposure and service calls, delivering higher uptime for critical loads. Five-jaw sockets and robust bus connections simplify wiring and provide a straightforward path to code-compliant metering without bypass options. The rugged enclosure also eases compliance with outdoor duty cycles and helps meet environmental requirements in various climates. With a 200A service rating and an 800A bus, the stack supports scalable submetering for growing sites, while 120/208 VAC compatibility broadens the range of downstream equipment. Electrical designers value the 120/208 VAC capability for downstream equipment compatibility, providing headroom for load growth and energy auditing. This helps procurement align with existing panel schedules and reduces rework during installations. UL-listed safety certification and Eaton’s warranty offer risk reduction and regulatory compliance across site inspections. The design supports seamless integration with CCV2_X, CCVH2_X, CVS2_XMM family metering components, enabling straightforward field upgrades and maintenance. The enclosure benefits from durable materials and a modular interior that accommodates different CTs and CT ratios, reducing the need for custom fabrication. Industry professionals benefit from faster commissioning due to standardized interfaces and clear metering pathways, which translates into quicker project handoffs and improved cash flow. The 3MM320RC’s design supports quick site surveys, simplified wiring diagrams, and predictable installation steps, helping field crews avoid rework. This translates to lower on-site labor costs, shorter project timelines, and higher reliability for energy data collection.
