Why do bathroom showers need to be connected to electrical cords?

Showers, toilets, water pipes, bathtubs, washbasins and other parts of the home that are prone to electricity leakage need to be connected to equipotential. Equipotential is not a ground wire, but it is an important device to connect the ground wire of the socket, connecting these metal parts to form an equipotential. When the electric potential is equal, there is no voltage and therefore no current.

For example, if we use an electric water heater at home, the shower part should be connected to the wire to prevent the current from being transmitted to the human body through the shower when the water heater leaks. If you directly smash the equipotential regardless of the consequences, and you can't install wires later, then the electricity in the bathroom is quite dangerous.

To use a simple analogy, equipotential terminals are equivalent to airbags in cars. Although there are very few opportunities to use it in daily life, once it is used, it is a life-saving measure. Moreover, there have been so many cases of electric shock accidents in the bathroom in recent years, and the state has long attached great importance to the safe use of electricity in the bathroom.

Therefore, when you decorate, you must be careful not to let the decoration workers smash this equipment, and of course, install wires on all metal equipment in the bathroom.

Lifeline. That's the grounding wire, which is used to prevent electric shock.
