How are the meter positions of the meter box distinguished?

Meter boxes usually contain multiple meter locations used to differentiate between electrical energy measurement and management for different circuits or uses. These meters are usually connected to the meter box through different wires and circuit breakers to achieve the following distinctions:

Main meter: The main meter is usually the main entry point into a home's electricity supply and is used to measure the total electrical energy consumption of the entire home. It is usually connected to the main circuit breaker in the meter box and can control the entire power supply.

Branch epitopes: Other epitopes in the meter box are often used to differentiate between different uses or different parts of the electrical energy consumption. For example, one epitope could be used to measure the power consumption of a lighting circuit, and another could be used to measure the power consumption of a large appliance such as an electric stove, washing machine, or air conditioner.

Subsites: Some meter boxes may also contain subsites to distinguish individual outlets or devices. This allows households to gain a more precise understanding of the energy consumption of different devices.

These meter points in the meter box are connected by wires to different branches in the home's circuit and are usually controlled and protected by corresponding circuit breakers. This hierarchical structure facilitates energy metering and management to control electricity bills, diagnose problems, and ensure the reliability of power distribution.
