Abb TM42420R 200A 42-circuit Meter Socket 3P4W

Product Description

The ABB TM42420R is a 200-amp, 42-circuit, 3-phase 4-wire meter socket designed for commercial and residential electrical metering applications. This unit provides a robust enclosure for utility-grade metering, supporting multi-family, light commercial, and similar installations where a single meter point feeds a 42-circuit distribution arrangement. Licensed electricians install this device at the service entrance, where it interfaces between the utility meter and the downstream panelboard or load center. The 3-phase 4-wire configuration makes it suitable for 120/208-volt or 120/240-volt systems depending on service type.

This meter socket is used in commercial and multi-tenant residential construction where the authority having jurisdiction and the serving utility require a dedicated metering enclosure at the point of service entry. The 42-circuit rating and 200-amp capacity make it well suited for applications with substantial downstream load distribution, including apartment buildings, strip commercial suites, and small industrial service points. Installation is coordinated with the local utility and must meet NEC service-entrance requirements.

Key Features

• 200-amp continuous rating supports high-capacity service entrance installations
• 42-circuit configuration accommodates large downstream distribution needs
• 3-phase 4-wire design compatible with both wye and applicable delta service configurations
• Utility-grade meter socket construction for permanent service entrance mounting
• Suitable for multi-family residential and light commercial metering applications

Compatibility

Designed as an OEM-style replacement or new-installation meter socket for 200-amp, 3-phase 4-wire service entrance applications requiring a 42-circuit metering enclosure.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NEC Article 230 service entrance requirements and all applicable local codes. Confirm utility approval and inspection requirements before mounting, as many jurisdictions require the serving utility to approve the meter socket model prior to installation. De-energize the service and coordinate with the utility for meter removal before any work on the enclosure. Do not exceed the 200-amp continuous rating of the device.
