Multiple metering
Multiple metering in a single stack enables precise tenant-level energy tracking, reducing billing disputes and speeding commissioning. This feature delivers faster project handoffs and lower field labor costs. It’s ideal for multi-tenant residential buildings and mixed-use facilities that require independent submetering. The 125A service with an 800A bus rating provides headroom for peak loads without panel upgrades, protecting your capital investment. Integrated configuration supports reliable fault isolation and smoother maintenance. Use cases include new builds and retrofits in urban housing where demand varies by unit and time of day. Indoor installation and five-jaw sockets simplify wiring and reduce weather exposure during installation. The 120/208 Vac capability aligns with common utility feeders, and three-phase in with single-phase out supports flexible submetering schemes. This flexibility helps contractors adapt to diverse site conditions. UL Listed certification reinforces safety and compliance with electrical codes, aiding faster inspections and fewer non-conformities. The warranty—one year from installation or eighteen months from shipment—reduces maintenance risk and supports budgeting. The design also integrates with Eaton MCBs for a smoother migration path. Long-term benefits include enhanced energy visibility, reduced energy waste, and easier data integration with building management systems. The compact footprint saves space in equipment rooms, boosting overall site efficiency. For procurement teams, the combination of performance and reliability helps achieve ROI targets through accurate metering and predictable maintenance.
