Abb TMPR8320R Meter Stack 800A 1-phase Ringless Socket

Product Description

The ABB TMPR8320R is a meter stack assembly designed for metered electrical distribution in residential and light commercial applications. It combines three 200-amp ringless meter sockets into a single 800-amp, single-phase stack configuration with 5-terminal wiring provisions. Meter stacks of this type are installed by licensed electricians to consolidate multiple utility metering points into one enclosure, simplifying wiring runs and meeting utility service entrance requirements. The ringless socket design eliminates the external locking ring, a configuration required by many utilities for ease of meter pull and tamper resistance.

This unit is suited for multi-tenant residential buildings, small apartment complexes, or commercial service entrances where individual tenant metering is required in a compact, code-compliant stack arrangement. The single-phase configuration makes it appropriate for standard utility service feeds serving residential loads. Electricians installing this assembly will typically work with a utility company for meter socket approval and final energization, as service entrance equipment is subject to utility acceptance before energization.

Key Features

• Three 200-amp ringless meter sockets in a single stacked enclosure
• 800-amp overall bus rating supports high-capacity single-phase service entrance applications
• Single-phase configuration compatible with standard residential and light commercial utility feeds
• 5-terminal wiring provisions for flexible metering and distribution connections
• Ringless socket design meets utility requirements where external locking rings are not permitted

Compatibility

Designed as an OEM-style meter stack assembly for single-phase service entrance installations requiring multiple ringless meter socket positions in a consolidated enclosure.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local utility service entrance requirements. De-energize the service entrance and coordinate with the serving utility before any work on meter socket equipment. Verify that the enclosure mounting surface, conduit entries, and grounding provisions comply with AHJ and utility specifications prior to final inspection and meter set.
