KS C IEC 61024-1 / 62305-1
3.1 Equipotential bonding
3.1.2 Equipotential bonding for metal equipment
If insulating parts are inserted into gas or water pipes, they must be bridged with surge suppressors having appropriate operating conditions.
Equipotential bonding can be done in the following ways:
- Use of bonding conductors when electrical continuity is not guaranteed by natural bonding.
- If it is not possible to install a bonding conductor, use a surge suppressor.

- Design of brain protection system
2.5 Design of internal brain protection system
2.5.2 Safety Distance
Conductors of power systems and communication equipment, as well as conductive parts of buildings and equipment installed within them, must be connected to equipotential bonding.
- Construction of an internal brain protection system
4.1 Equipotential bonding of internal conductors
Bonding shall be performed so that internal conductive parts, external conductive parts, power systems and communication systems (e.g. computers and security systems) are bonded with short bonding conductors, using surge suppressors (SPDs) if necessary. All bonding shall comply with KS C IEC 60364.
