Technical reference Earthing standards
of equipotential bonding measures to cover exposed and conductive metal parts is further recommended to protect against step and touch voltages, and to remove risk of dangerous sparking. Five classes of low voltage electrical installation are defined within the standard - TN-S, TN-C, TN-C-S, TT and IT.

We learned already that the electric field is perpendicular to the surface of a conductor (otherwise charges would accelerate along the surface), and equipotential lines are always perpendicular to the electric field lines. Example: Let’s consider as an example 2 conducting spheres connected by a thin conducting wire.
