Can the plasma potential in the bathroom at home be covered during decoration?

You can cover it, as long as it's not broken. The property is concerned about the location of the high-voltage electric box and the location of the gas meter. The load-bearing wall can't be dismantled, and it can't be cut when it meets steel bars. Otherwise, the property will deduct the decoration deposit.

The plasma potential box in the bathroom is to prevent people from getting an electric shock when the metal objects in the bathroom are charged. If it is changed to plastic, it will not be able to prevent electric shock.

The potential box is an equipotential bonding device. If the metal object in the bathroom is short-circuited, that is to say, the shell is charged. At this time, if your hand touches the electrical appliance shell and your foot steps on the ground, the voltage between your hands and feet will be greater than 25V in a humid environment, which will cause harm. If the shell of the electrical appliance is connected by this equipotential connection device, that is to say, the shell of the electrical appliance is equipotential with the ground, so that the voltage difference between the hands and feet is very small when the hand touches the shell, and an electric shock accident will not occur.
