Abb TLM3220RCU Meter Socket 200A 32 Circuit 1P3W

Product Description

The ABB TLM3220RCU is a meter socket designed for residential and light commercial electrical metering applications. This unit supports a 1-phase, 3-wire (1P3W) configuration and is rated for 200 amps, making it suited for standard service entrance installations. It accommodates up to 32 circuits, combining metering and load-center functionality in a single enclosure. Licensed electricians install this device at the service entrance as part of a utility-approved metering assembly. The combination of meter socket and circuit capacity simplifies the service entrance layout and reduces the number of separate enclosures required on the structure.

The TLM3220RCU is intended for single-phase residential service entrances and light commercial applications where utility metering and circuit distribution are handled at one point. Its 1P3W configuration is standard for North American 120/240-volt split-phase residential service. This unit is appropriate for new construction and retrofit installations where a self-contained meter-main assembly is required by the utility or local authority having jurisdiction.

Key Features

• 200-amp service rating supports standard residential and light commercial loads
• 32-circuit capacity integrates metering and distribution in one enclosure
• 1-phase, 3-wire (1P3W) configuration matches standard North American split-phase service
• Designed for service entrance installation as a meter socket assembly

Compatibility

Designed as an OEM-style meter socket for single-phase, 3-wire residential and light commercial service entrance applications rated at 200 amps.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. The utility service must be de-energized and the authority having jurisdiction or utility company must be notified before installation or removal of the meter socket. Verify that the enclosure rating and mounting provisions meet local utility requirements before rough-in. Do not energize the assembly until all wiring connections have been inspected and approved.
