FAQs
Install the 1M1R F in a B-Line series meter enclosure using the single meter position configuration. Ensure the main circuit breaker is (1) 100 A, 2P, and connect the aluminum bus to the neutral and hot lugs per Eaton's mounting guidelines. The flush mount and AW hub support clean, code-compliant wiring with straightforward field maintenance.
Key specifications include 100 A amperage rating, 120/240 V voltage rating, single-phase configuration, and a 10 kAIC interrupt rating. The unit is UL listed and designed for a single meter position, with a galvanized steel housing and ANSI 61 gray finish. Confirm compatibility with your service entrance or branch circuits before installation.
Yes. The Eaton 1M1R F is designed to support a single meter position and can accommodate ring or ringless metering configurations, depending on enclosure design and utility requirements. Verify with the project’s metering plan and local code to determine the optimal configuration and any additional accessories needed.
Highlight UL listing and EUSERC approval as core compliance signals. Also reference the 100 A, 120/240 V single‑phase rating and 10 kAIC interrupt capability, which align with typical utility and building code expectations for meter protection equipment in commercial installations.
The galvanized steel frame with ANSI 61 gray finish and aluminum bus provides corrosion resistance and durable service life, reducing repainting and replacement needs. Its compact depth supports higher panel density, lowering installation time and ongoing maintenance costs, while UL/EUSERC compliance supports smoother project approvals and long-term operational reliability.
