Eaton Specification Sheet - U121314
100A amperage rating provides capacity for standard service loads without upgrading interior gear, reducing upfront costs and panel changes. This translates to faster project turnover and predictable performance in commercial and light-industrial facilities. Steel construction with ANSI 61 paint delivers corrosion resistance in exposed or damp environments, decreasing maintenance cycles and extending service life while maintaining a professional enclosure appearance. Four-jaw, ring-type construction with side mounting ensures secure connections and minimizes field wiring errors, shortening installation time and improving insulation integrity in crowded electrical rooms. The three-wire configuration with #14-2/0 lugs supports flexible feeder wiring while keeping termination practices code-compliant, and the ring cover offers convenient access during maintenance. Manual circuit closing as a bypass option enables rapid load isolation during commissioning or changes, reducing downtime. AW Hub top provision improves compatibility with a range of meter bases, while UL Listed certification provides installer confidence and procurement consistency for both Eaton and third-party systems.

This configuration shortens install time and reduces errors when routing feeders in crowded enclosures.
The unit is rated for 100A, configured as a 1-pole, 3-wire meter socket with line and load lug sizes of #14-2/0. It features a four-jaw ring design and a ring-type cover, enabling secure and reliable termination of conductors. The combination supports typical service entrance applications with compliant wiring practices and straightforward field termination.
Yes, U121314 is UL Listed, reflecting verified safety and electrical performance. It also carries a NEMA 3-style protection reference, indicating suitability for outdoor or exposed environments when installed per manufacturer guidance. The ANSI 61 painted steel enclosure provides additional corrosion resistance, making it practical for exterior service connections in appropriate climates.
This meter socket excels in commercial and light-industrial service panels, outdoor service entrances, and retrofit projects requiring dependable 100A metering with a compact, side-mount profile. Its four-jaw ring design and three-wire configuration support robust terminations for standard feeders, while the durable steel/ANSI 61 finish reduces maintenance cycles in challenging environments.
Key ROI drivers include the 100A capacity reducing the need for upgrades, side mounting that fits tight spaces, and a durable ANSI 61 painted steel enclosure that lowers maintenance costs. The four-jaw ring design speeds up wiring, and the optional AW Hub top provision improves compatibility with a range of meter bases, simplifying procurement and reducing field adjustments.
