Abb TM2020RCU Meter Socket 200A 1P 120/240V 22kaic

Product Description

The ABB TM2020RCU is a 200-amp, 20-jaw, single-phase, three-wire meter socket rated for 120/240 volts with a 22,000-amp interrupting capacity (22kAIC). It is housed in a NEMA 3R enclosure, making it suitable for outdoor installations where rain and ice protection is required. Designed for use by licensed electricians on residential and light commercial service entrances, this meter socket provides the connection point between the utility meter and the downstream load center or distribution panel. The 22kAIC short-circuit rating meets standard utility and inspection requirements for most residential services.

This meter socket is intended for single-phase, three-wire 120/240-volt residential service entrance applications. It is typically installed at the point where overhead or underground utility service enters a structure, mounting to an exterior wall or meter base pedestal. The NEMA 3R rating makes it appropriate for exposed outdoor locations. Electricians install this unit as part of a complete service entrance assembly alongside a weatherhead, service entrance cable, and main disconnect or combination meter-main panel.

Key Features

• 200-amp continuous current rating for standard residential service
• 20-jaw configuration accepts standard utility meter form factors
• Single-phase, three-wire (1P3W) 120/240-volt service compatibility
• 22kAIC interrupting capacity meets typical utility short-circuit requirements
• NEMA 3R enclosure rated for outdoor use with rain and ice protection

Compatibility

Designed as an OEM-style replacement or new-installation meter socket for single-phase, three-wire 120/240-volt residential and light commercial service entrance applications requiring a 20-jaw, 200-amp socket in a NEMA 3R enclosure.

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 and verify the service is dead before any work begins — meter socket installation involves utility-side conductors that may remain energized until the utility pulls the meter. Mount the enclosure plumb and level to an exterior surface rated to support the assembly, and ensure all conduit entries are properly sealed to maintain the NEMA 3R rating.
