1-Gang 200A 600V Single-Phase Meter Socket 1003878ACH

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).
