Abb TMPR12212R Meter Stack 1200A 1-phase Ringless Socket

Product Description

The ABB TMPR12212R is a meter stack assembly configured for two 125-amp ringless meter sockets rated at 1200 amps total capacity on a single-phase system. This unit provides a compact, multi-position metering solution used in residential and light commercial electrical distribution applications. It supports a 5-terminal configuration and is designed for installations requiring multiple metered service positions within a single enclosure stack. Licensed electricians install this assembly as part of a main service entrance or sub-metering arrangement.

This meter stack is suited for single-phase service entrance installations where multiple tenant or unit metering is required in a consolidated footprint. The ringless socket design eliminates the need for a meter ring during meter installation or removal, which is a common utility and installer preference in many regions. Typical applications include small multi-family residential buildings, light commercial properties, and any site requiring dual 125-amp metered positions under a 1200-amp service.

Key Features

• Dual 125-amp ringless meter socket positions in a single stacked assembly
• 1200-amp total service rating supports high-capacity single-phase distribution
• Single-phase configuration for standard residential and light commercial service entrances
• 5-terminal wiring configuration for proper service entrance conductors
• Ringless socket design for tool-free meter installation and removal per utility requirements

Compatibility

Designed as an OEM-style replacement and new-installation meter stack for single-phase ringless socket service entrance assemblies rated at 1200 amps with dual 125-amp metering positions.

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 assembly. Verify that conductor sizing, conduit fill, and grounding arrangements comply with NEC Article 230 for service entrance equipment. Do not reinstall meters or restore power until the utility has inspected and approved the installation where required.
