Abb TMPR12122R Meter Stack 1200A 1-phase Ringless Socket

Product Description

The ABB TMPR12122R is a single-phase meter stack module designed for residential and light commercial metering applications. This Meter Mod III configuration features a 1200-amp bus rating with a 225-amp ringless socket, providing a compact, code-ready metering point for utility service entrances. The ringless socket design eliminates the need for a meter ring, simplifying installation and reducing hardware count. Licensed electricians install this unit as part of a complete metering assembly on overhead or underground service entrance systems.

This meter stack is suited for single-phase residential service entrance installations where a high-capacity bus is required. The 1200-amp bus capacity supports demanding load centers while the 225-amp ringless socket accommodates standard utility metering requirements. It is intended for use in modular meter stack assemblies, commonly installed in multi-family residential buildings, manufactured housing developments, and commercial pad-mounted service configurations.

Key Features

• 1200-amp bus rating for high-capacity single-phase service entrance applications

• Single-phase configuration suitable for standard residential and light commercial utility metering
• Meter Mod III modular design for use in stackable metering assemblies
• Ringless socket format compatible with standard utility meter acceptance requirements

Compatibility

Designed as an OEM-style replacement or new-installation component for single-phase modular meter stack assemblies requiring a 1200-amp bus with a 225-amp ringless socket configuration.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local utility requirements. De-energize the service entrance and coordinate with the local utility before installing or servicing any meter socket component. Verify that the bus rating and socket ampacity match the service entrance conductors and utility metering specifications before mounting. Follow the manufacturer assembly instructions for proper torque and alignment within the modular stack.
