This unit provides a 400-amp main lug-only configuration with four 125-amp meter sockets in a 1-phase, 3-wire arrangement. The NEMA 3R enclosure provides protection against rain, sleet, and windblown debris, making it suitable for outdoor installations. The ringless socket design eliminates the need for a meter ring during installation and service. This meter stack carries Duke Energy approval, meeting that utility's specific requirements for metered service entrance equipment. Licensed electricians install this type of equipment at the service entrance level.\u003c\/p\u003e\n\u003cp\u003eThis meter stack is used in residential and light commercial multi-family applications where four individual metered services are required from a single 400-amp service entrance. Typical installations include duplexes, fourplexes, apartment buildings, and similar multi-tenant structures where each unit requires a separately metered 125-amp, 1-phase, 3-wire service. The outdoor-rated NEMA 3R enclosure suits installations on exterior walls or in utility areas subject to weather exposure. Duke Energy utility service territories that require ringless meter sockets are the primary deployment environment for this unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e400-amp main lug-only (MLO) service entrance rating across four sockets\u003c\/li\u003e\n  \u003cli\u003eFour 125-amp, 1-phase, 3-wire (1P3W) meter sockets in a single stackable module\u003c\/li\u003e\n  \u003cli\u003eRingless socket design for simplified metering and utility access\u003c\/li\u003e\n  \u003cli\u003eNEMA 3R enclosure rated for outdoor use, resistant to rain and windblown debris\u003c\/li\u003e\n  \u003cli\u003eDuke Energy approved for use in qualifying utility service territories\u003c\/li\u003e\n  \u003cli\u003eMiniMod modular platform supports stacking and service entrance configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eApproved for use in Duke Energy service territories requiring ringless meter sockets.
