How are the meter positions of the meter box distinguished?

The meters of the meter box are usually distinguished according to the purpose of the circuit and the power demand. Different meters have different purposes and are usually divided into the following types:

1. Total meter position: used to install the main incoming electricity meter, which is used to measure the total electricity consumption of the entire building or a certain area.

2. Sub-meter: An electric meter used to install branch circuits to measure the electricity consumption of a certain area or equipment.

3. Spare meter: used to install a spare meter in case of emergency.

4. Control meter position: an electric meter used to install control circuits or measure the electricity consumption of low-power equipment.

5. Special meter: used to measure the power consumption of special circuits or special equipment, such as air conditioners, elevators, etc.

When installing the meter box, it is necessary to design the number and type of meters according to the electricity demand and circuit planning, so as to ensure that the meter box can meet the electricity demand of electrical equipment and comply with relevant safety regulations and standards. When using the meter box, it is also necessary to pay attention to regular inspection and maintenance to ensure the safety and reliability of the meter box.
