For concrete floor tiles with steel bars, the steel bars are sealed in the concrete floor tiles, and the human body is not damaged by the concrete floor tiles. It does not touch the steel bar, it does not consider the conductive part outside the device, so it is not necessary to incorporate the additional protection equipotential bonding. Reinforced concrete floor tiles and their outer sheaths and topsoil (such as grass) are not considered for the conductive parts outside the device, and do not need to be included Protect the equipotential bonding.
Note 4. The following conductive parts are usually not required to be included in the additional protection equipotential bonding. ---The ladder and shelter of the pool;
