Each of these earthing methods is given below.
 Equipotential Bonding System
Equipotential bonding is an earthing method in which steel frames and building structures, metal
ducts and pipes, and metal structures in floors are connected together and make connections to the
earth trunk line to achieve a uniform potential everywhere across the entire building. We recom-
mend this earthing method.
The following figure shows an example of an equipotential bonding system.
Connect the main earthing terminal and building structures together with equipotential bonding con-
ductors and embed the mesh ground line in each floor.
Connect the ground line of each control panel to the equipotential bonding system.
