200A Meter Socket Base with Lockable Cover

A meter socket (also called a meter base, meter pan, or meter enclosure) is a dedicated electrical box that holds an electric utility meter. It acts as the critical connection point between the utility's power lines and a building's main electrical panel, measuring electricity consumption.

Main types include: Single-phase (standard for residential homes), Three-phase (for commercial/industrial buildings), Ring-type vs. ringless meter sockets, and Overhead/underground service-rated enclosures. They are also classified by amperage (100A, 200A, 320A, 400A) and voltage rating.

Ring-type sockets use a metal security ring to lock the utility meter in place, requiring utility tools for removal. Ringless sockets use a lever/latch mechanism for easier, secure meter access, widely used in modern residential installations.

No. Meter sockets connect to high-voltage utility power and must follow local electrical codes (NEC, IEC, etc.). Installation, wiring, and utility-side connections must be done by a licensed electrician or authorized utility personnel. Unauthorized work risks electrocution, fire, and utility penalties.

Most modern homes require a 200A meter socket. Older homes may use 100A. Commercial/industrial applications typically need 320A, 400A, or higher three-phase sockets. Match the rating to your main electrical panel and utility service capacity.
