Why are both the neutral wire and the ground wire charged after the live wire is connected to the ground?
If the live wire is connected to the ground wire, a short circuit will occur, and current will flow outward through the ground wire. In electrical circuits, the neutral wire is usually connected to the ground wire; therefore, when the live wire makes contact with the ground wire, current can also flow back to the power source through the neutral wire, so the neutral wire can also become charged. Furthermore, insufficient ground resistance or faults in the grounding circuit can also cause the neutral wire to become live. Therefore, when dealing with this situation, it is necessary to ensure that all circuits are properly grounded and that the grounding resistance remains low. At the same time, safety measures are also necessary, such as wearing insulated gloves. .
Perhaps yours has a TN-C-S type grounding system
Once the live wire is connected to ground, both the neutral wire and the ground wire become charged – won’t the switch trip in that case?
First, check what type of grounding system it is, and then see what the grounding resistance is If there is current, there must be a voltage difference; local equipotential bonding can eliminate this
