Abb TMPR8412RF Meter Stack 4-socket Ringless 800A

Product Description

The ABB TMPR8412RF is a 4-socket ringless meter stack rated for 800 amps at 1-phase, 5-terminal configuration. Each of the four socket positions accepts up to 125-amp metering, making this unit suited for multi-tenant residential or light commercial applications where individual unit metering is required on a single service. The ringless socket design eliminates the need for a pull-out ring, streamlining meter installation and removal for utility personnel. This assembly carries Duke Energy approval, meaning it meets that utility's specific construction and safety requirements for approved metering equipment.

This meter stack is used in multifamily residential buildings, apartment complexes, condominiums, and small commercial properties where up to four tenants or units must be metered individually on a shared 1-phase service. The 800-amp main rating accommodates the combined load of four 125-amp circuits. Duke-approved labeling indicates this unit has been reviewed and accepted for installations within Duke Energy service territories, which may be a required condition for final utility connection and inspection.
