Precautions for the incoming and outgoing lines of the outdoor meter box

The incoming and outgoing lines of the outdoor meter box are an important part of connecting the outdoor power grid and the indoor power grid. The following are the precautions:

1. Select the appropriate cable: According to the actual power demand, select the cable that meets the standard, including the cross-sectional area of the conductor and the insulating material.

2. Select the appropriate inlet and outlet: the inlet and outlet should be selected above the outdoor meter box, and the location should be appropriate to avoid damage to the cable caused by water, dust and corrosive gases at the inlet and outlet.

3. Protective joints: The joints of the incoming and outgoing lines should be protected to prevent the joints from being damaged by the outside world and affecting the safety of electricity use.

4. Correct wiring: When wiring, you should strictly follow the requirements of cable color and model to ensure the correctness and safety of wiring.

5. Use insulating material: Use insulating material at the inlet and outlet to ensure that the cable insulating material will not be damaged by factors such as the external environment.

Regular inspection: Regularly check the connection of the incoming and outgoing lines, and replace them in time if the connection is found to be damaged or corroded, so as to ensure electrical safety.

In short, when installing the incoming and outgoing lines of the outdoor meter box, you must operate in accordance with relevant standards, pay attention to safety, and carry out regular inspections and maintenance to ensure electrical safety.
