125A 120/208VAC 2-Gang Meter Pack with Horn Bypass 3MM212RRLB

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).

A 200-amp meter socket with a disconnect lets you manually shut off power. A 200-amp meter socket with a main breaker does that and also protects against overloads or short circuits. It is required when local code mandates a main service disconnect at the meter location.

Yes, if your home has a 200-amp service. Homes using more than 10–12 kW of peak demand usually need this rating. So yes, a 200-amp meter is required for a modern home with high power demand.

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.

A 2-gang meter socket is an enclosure with two meter positions, used to supply separate electric service to two units, such as a duplex or a split commercial space.

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.

Use a 2-gang, 3-gang, or 4-gang meter socket, respectively.

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.

Yes, if your panel and utility service support the upgrade. A permit and utility coordination are usually required.

Horn bypass has two metal prongs ("horns") where jumper cables are manually attached. This is common for residential or small-scale applications.

Lever bypass includes a built-in lever that activates the bypass internally. It is safer and faster for commercial applications with frequent service.

A bypass allows power to keep flowing when the meter is removed. This is useful during maintenance or meter replacement without shutting off electricity to the building.

• 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.
