Problems of Attention in Low-voltage Charging and Overhauling Work

1) Low-voltage electrical work must be supervised by trained personnel. Always use tools with insulated handles to avoid electric shocks. Ensure the working area is dry and insulated, and wear protective gloves along with a safety helmet. Workers should wear long-sleeve clothing to minimize exposure. It is strictly prohibited to use metal tools such as hammers, rulers, or brushes that could cause short circuits or sparks.

2) High and low voltage cables should be installed on the same pole. Before working on low-voltage lines, always check the distance from high-voltage lines and implement measures to prevent accidental contact with live parts. This ensures a safe working environment and reduces the risk of severe electrical accidents.

3) Workers must not pass through areas where low-voltage live conductors are not properly insulated. When working on live low-voltage distribution panels, isolation barriers or insulating mats should be used to prevent phase-to-phase short circuits and single-phase grounding, which can lead to dangerous situations.

4) Before disconnecting any wires, identify and mark the phase and neutral lines. Choose an appropriate working position to maintain control during the process. When cutting wires, always disconnect the phase wire first, followed by the neutral wire. If wires are crossed, reverse the order. Avoid performing wiring or disconnection under load whenever possible to ensure safety.

5) Never touch two different wires at the same time. This can create a path for electric current through the body, leading to serious injury or electrocution.

6) Live electrical components should only be located on one side of the worker, ensuring that no part of the body comes into contact with them during the operation.
