The 400A amperage rating ensures the meter stack can handle peak commercial loads while maintaining safe, predictable fault margins. This capability translates into reduced electrical bottlenecks and improved demand management for facilities like shopping centers, office campuses, and light industrial sites. Two sockets enable modular metering and easier tenant separation within shared service feeders, simplifying phase balance and accelerating commissioning in three-phase networks such as 208Y/120V environments. The ringless cover enhances safety for technicians and speeds maintenance, cutting service time and minimizing disruption during panel upgrades. Aluminum bus construction provides robust current handling with lighter weight and corrosion resistance, enabling easier field installation and long-term reliability. UL Listed certification confirms compliance with electrical safety standards, easing inspections and regulatory approvals across commercial projects. Finally, the overall footprint supports careful space planning in retrofit projects, with compatibility across standard Eaton and compatible third-party panels to minimize integration risk.
