4 Terminal 3-Position 125A Ringless Meter Socket U6123-X-BL

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).

It’s used for 100 amp service, common in small homes under 1,000 sq ft, such as cabins, cottages, or older single-family houses with basic electric heating and appliances.

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.

 Yes, a multi-gang meter socket allows each unit to have its own meter and separate billing.

Gang sockets combine multiple meters in one enclosure — neater and more cost-efficient for multi-unit buildings.

 Yes, most utilities and codes require a separate disconnect for each meter position.

It protects internal components from the weather. Replace it if it is cracked or no longer seals properly.

Yes, if compatible, but full replacement is safer.

• Solar-ready: Includes space for a solar production meter or uses a socket adapter.
• Generator-ready: Has a bypass or interlock that allows generator connection when utility power is out.

Use the one that matches your utility’s net metering or backup power interconnection rules.

Only if rated and approved for the application.

Yes. These are designed for duplexes, small apartments, or commercial properties where each unit has a separate utility meter.

Yes. UL listing (specifically UL 414) ensures the socket meets national safety standards for electric meter mounting devices. Most utilities require UL-listed equipment.

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.
