1-Gang 20A 600V Three-Phase Instrument Rated Meter Socket USTH81A194CH

A meter socket is a weatherproof enclosure that houses the electric meter and connects your service entrance conductors to the utility’s power lines. It allows the utility to measure your electricity usage and acts as a safe, secure interface between their system and your home’s wiring. Without it, your electric meter can’t function, and power can’t legally or safely be delivered to the home.

• Main breaker socket: Includes a built-in breaker for disconnecting service.
• Main lug socket: No breaker, just lugs for wire terminations; requires a separate disconnect.
• Ring-type socket: A locking ring is used to secure the meter (often required by utilities).
• Ringless socket: Holds the meter with clips; makes it easier to access for service.
• Overhead socket: Accepts power from overhead utility lines.
• Underground socket: Accepts power from underground service laterals.
• Bypass socket: Includes a mechanism to maintain service during meter removal.

Multi-position socket: Allows for two or more meters in a single enclosure (e.g., apartments).

Signs for a replacement include burn marks, loose meter jaws, rust/corrosion, or cracked housing. Minor wear (like a worn cover or missing knockout plug) can be repaired, but internal damage or safety risks require full replacement.

These terms are often used interchangeably, but “meter socket” is the more technical term referring to the component that holds and connects the meter. “Meter base” is more common in utility and construction slang. The difference in terminology often comes down to regional usage or whether you're talking about the complete assembly (base) or just the socket component.

The homeowner provides and maintains the meter socket, which a licensed electrician must install. The utility installs and owns the meter itself. If the socket is damaged, it's the homeowner’s job to repair or replace it by calling a licensed electrician.
