Bathrooms are places with a high humidity level. Coupled with a large number of electrical appliances (washing machines, dryers, etc.) and power outlets, these places are considered high-risk areas. If the insulation of wires is weakened or broken due to mechanical damage, the current will leak to the metal parts of the electrical appliances and water pipes. Therefore, to protect yourself and your family, it is especially important to make a proper grounding in the bathroom.
Usually, iron baths that conduct electricity very well are installed in the bathrooms, especially in old buildings. It is not difficult to ground them. To do this, connect a grounding conductor to the metal legs of the bath. The other end of the conductor should be connected to the grounding bus located in the equipotential bonding box.
All other electric appliances in the bathroom, including a washing machine, a water heater, an exhaust fan and so on, are also connected to this box. The grounding conductor from the equipotential bonding box is connected to the main ground bus located in the panel.
Voila! You can enjoy bathing safely.
