Eaton 37MM420R12 Meter Stack 200A 3-phase 4-gang

Product Description

The EATON 37MM420R12 is a 4-gang meter stack rated for 200 amps per section, configured for 3-phase, 4-wire service. It is designed for use in multi-tenant residential and light commercial electrical distribution systems where multiple metered services must be consolidated into a single enclosure. Licensed electricians install this unit as part of a service entrance assembly, typically in conjunction with a main disconnect. The stack configuration supports up to four individual meter sockets within a single modular housing, streamlining installations where separate utility meters are required per unit or tenant.

This meter stack is suited for multi-family residential buildings, commercial strip centers, and similar applications requiring multiple independently metered services fed from a common 3-phase source. The 4-wire configuration accommodates standard 120/208-volt or 277/480-volt 3-phase wye service entrances. It is intended for outdoor or indoor use depending on the enclosure rating of the installation site, and is typically mounted to a structural wall or meter bank pedestal per local utility requirements and NEC guidelines.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 230 governing service entrance equipment and local utility metering requirements. Verify that utility approval is obtained before final connection to the line side of the meter stack. De-energize all upstream service conductors and follow proper lockout/tagout procedures before working inside the enclosure. At 170 pounds, this unit requires two-person handling or mechanical assistance during mounting to prevent injury and enclosure damage.
