What are the differences between live wire leakage and neutral wire leakage?

 live wire leakage and neutral wire leakage:

### Principles

- **Live wire leakage**: The live wire is the main path for carrying current transmission in the power system. When the

 insulation layer between the live wire and the ground or a conductor is damaged and a short circuit occurs, the current

 will flow from the live wire to the ground and return to the power source through the grounding point.

- **Neutral wire leakage**: The neutral wire is the neutral line in the power system and is used in pairs with the live wire

 to provide a closed loop path. When the insulation between the neutral wire and the ground or a conductor is damaged, 

the current will flow back to the ground wire through the short circuit path.

### Characteristics

- **Live wire leakage**:

    - **Circuit interruption**: The leakage protector or fuse is likely to be triggered, causing the circuit to be interrupted to

 prevent the current from continuing to flow.

    - **Abnormal heating**: The circuit components around the leakage point will heat up abnormally due to the leakage 

current, and there may be smoke, a burnt smell, and even a fire.

    - **Voltage drop**: Since part of the current flows to the ground through the leakage loop, the voltage in the circuit will 

drop.

- **Neutral wire leakage**:

    - **Current imbalance**: The current in the circuit is no longer equal among the phases, and part of the current flows to 

the ground through the leakage loop.

    - **Unstable voltage**: It will cause voltage fluctuations in the circuit, resulting in unstable voltage of the power supply 

equipment, which may damage the equipment or cause other failures.

    - **Increased ground wire current**: The leakage current returns to the power source through the grounding point, 

resulting in an increase in the current in the ground wire of the circuit.

    - **Increased neutral wire temperature**: The temperature of the neutral wire near the leakage point will rise, and it may

feel hot to the touch.

    - **Discoloration of the neutral wire**: Neutral wire leakage may cause local overheating, resulting in discoloration, 

carbonization or rupture of the insulation layer of the neutral wire.

### Detection methods

- **Live wire leakage**:

    - **Reset test**: After the protector trips, press the reset button. If the switch does not respond and cannot be pushed up, 

it may be that the live wire is leaking.

    - **Multimeter detection**: Turn off all electrical equipment and switches, turn on the main switch, and use the resistance

 range (set to the maximum) of the multimeter to measure the wires. If there is a value, it indicates that the live wire is leaking.

 You can also use a digital multimeter to measure the voltage. Insert the current clamp into the circuit. If the voltage value is 0, 

it may be that the live wire is leaking.

- **Neutral wire leakage**:

    - **Load test**: First close the switch. If it continues to trip, disconnect all the loads. If the switch can be closed, it may be

 that the neutral wire is leaking.

    - **Multimeter detection**: Use the resistance range (set to the maximum) of the multimeter to measure the resistance 

between the neutral wire and the ground. If there is a value, it indicates that the neutral wire is leaking; if the resistance is infinite, 

the neutral wire is not leaking. At the same time, it is also necessary to check the insulation layer of the neutral wire to see if there

 are any signs of damage, discoloration or carbonization.
