Eaton 1MM312RRL Residential Meter Stack - UL Listed

Feature is an outdoor, aluminum, ringless meter stack enclosure rated for 125A with an 800A bus rating. Business impact is improved service reliability for residential feed, enabling a compact footprint that lowers space requirements at the service entrance. Application includes single-phase in/out metering for 120/240V systems in outdoor environments, supporting three sockets and easy integration with typical main circuit breakers. A second feature is UL Listed certification and broad utility approvals, which translates to faster permitting and assured code compliance. This supports faster project timelines and reduced rework in field installations. A third feature is rugged outdoor construction with a 41.8 inch height, 12.26 inch width, and 7.01 inch depth, facilitating mounting in constrained spaces while maintaining safe clearance. The fourth feature is a 70 lb weight that balances sturdy protection with manageable handling during installation. Together these elements deliver measurable ROI through lower maintenance costs and extended service life, especially in outdoor, residential, and light commercial metering scenarios. The enclosure’s aluminum, ringless design minimizes corrosion risk and simplifies replacement of components, contributing to long-term cost efficiency. Compatibility with multiple utility approvals and standard metering configurations reduces engineering time and accelerates deployment in new or upgraded service entrances. Industry-specific context, including ME and NC utility alignment, ensures the solution fits a wide range of regional requirements while maintaining consistent performance under outdoor conditions.
