The operation of PC meter boxes (i.e. polycarbonate meter boxes) is an important process involving electrical safety and material characteristics. The following are the precautions to be taken when operating PC meter boxes:

Electrical safety:

Before operating the meter box, it is necessary to ensure that you have basic electrical knowledge and understand relevant safety regulations.

Be sure to turn off the power before operation to prevent electric shock accidents. The usual way to turn off the power is to find the main switch inside the meter box and switch it to the "off" position.

Use appropriate tools to open the meter box, avoiding forced opening to avoid damaging the meter box or causing safety issues.

After opening the meter box, check for any obvious damage or abnormal conditions inside, such as exposed wires, aging equipment, etc.

Material characteristics:

Although PC meter boxes have excellent insulation performance and weather resistance, they still need to avoid prolonged direct sunlight and high temperature environments to prevent material aging.

Avoid using sharp tools or hard objects to scratch the surface of the meter box during operation to prevent damage to its protective layer.

Operating standards:

The sequence of power transmission operation is: main distribution box → distribution box → switch box; The sequence of power outage operation is: switch box → distribution box → main distribution box (except for emergency fault situations).

After completing the operation, it is necessary to carefully check whether all steps have been executed correctly and ensure that the meter box door is securely closed.

Environment and Safety:

Keep hands dry and avoid wearing metal jewelry to prevent electric shock.

Ensure good ventilation in the surrounding environment and avoid operating the meter box in damp or enclosed spaces.

In summary, when operating a PC meter box, it is important to pay attention to electrical safety, material characteristics, operating standards, as well as environmental and safety issues to ensure the safety and effectiveness of the operation.
