How is the equipotential line of the faucet in the bathroom connected?

All metal utensils in the bathroom, all items that may be electrified, such as towel rails, water heaters, etc.

It's better to use dark money. Don't put switches or the like in the bathroom.

Theoretically, it works, but therefore the cost will be very high, first of all, the overall insulation of the bathroom can achieve equipotential, that is to say, to create a completely insulated small bathroom in the bathroom.

The equipotential box is generally in the basement floor, first of all, when doing the foundation, the upper lead reserved by the foundation grounding network has to be connected to the main distribution box through the long welding of the flat steel and the main reinforcement, and it is upstairs.

The isopotential of the restroom is a local equipotential.

Not connected to total equipotential.

Nowadays, most homes use plastic pipes, and it is useless to connect the equipotential wire to the faucet, hehe.
