Siemens WPL4412RJ Meter Socket 400A 4 Jaw Single Phase

Product Description

The SIEMENS WPL4412RJ is a 400-amp, single-phase, 4-jaw ringless meter socket designed for residential and light commercial electrical service entrances. This meter socket provides a secure, code-ready mounting point for utility-grade watt-hour meters and is rated for the full 400-amp service capacity required in modern high-demand installations. Licensed electricians install this unit as part of a service entrance assembly, typically at the point of delivery between the utility meter and the main distribution panel. The 4-jaw configuration accepts standard single-phase utility meters.

This meter socket is suited for single-phase electrical service entrance installations in residential and light commercial applications. The ringless design eliminates the traditional ring-and-socket sealing ring, simplifying meter installation and removal by utility personnel. At 400 amps, it supports heavy-load service entrance configurations including large residential homes, small commercial buildings, or multi-unit applications where elevated service capacity is required.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local utility requirements.
