Suitable for neutral or live wire leakage in socket loop. This scheme has great limitations, but the available frequency is not low.

Find out the grounding wire in the loop from the distribution box and grounding rod, remove it from the grounding rod, replace the original fault wire and connect it to the lower opening of the circuit breaker. Connect the original faulty wire to the grounding bar. (Is the fault line a neutral line or a live line? Which one is it? You can use the ground wire to switch one by one to see if the circuit breaker continues to trip. )

It should be noted that all sockets, ground wires and fault wires under this circuit should be replaced after wire replacement.

Second, wear steel wire

Suitable for short distance or embedded threading steel wire during decoration.

If possible, try to pull the broken old iron wire out of the threading pipe. If you really can't pull it out, you can also stay in the threading pipe. If there is no embedded threading steel wire during decoration, you can try it with threading steel wire during maintenance. It is easier to thread the steel wire into the threading pipe than directly. This method is feasible if the distance is short and the angle is small.

After passing through the threaded steel wire, the new steel wire can be pulled in.

Extended data:

In order to facilitate the replacement of wires in line construction, the following points need to be done.

1. Live line technology.

Therefore, the live line technology says that all wires can twitch, and its laying method is usually to find the nearest line path to lay pipes, while the walls are horizontal and vertical.

2. Wire selection.

Using wires with suitable wire diameters can fully ensure the stability of power supply, reserve the wire load margin and effectively prolong the service life of wires, such as lamp wires 1.5 square meters, socket wires 2.5 square meters and air conditioning wires 4 square meters. It is not common for home improvement wires to be damaged due to aging. If there is a problem, use an open wire to connect the circuit. On the one hand, it is convenient to change lines, on the other hand, there is no need to dig the ground and dig the wall.
