Correct use equipotential bonding systems pre-
vents dangerous touch voltages between system com-
ponents.g.
3. potentially explosive areas, where explicit
normative requirements apply, additional protective
equipotential bonding must implemented.
Protective equipotential bonding
All extraneous conductive parts routed into the build-
ing must connected with one another order to
prevent differences potential.

• Foundation earth electrodes
• Lightning protection earthing
• Conductor for protective equipotential bonding
• Protective conductors within the electrical system
• Metallic water, gas and heating lines
• Antenna earthing
• Metal parts the building, e.1 Planning methods
To avoid potential differences, the following system
components must connected, via the main earthing
busbar, with equipotential bonding cables accord-
ance with IEC 60364-5-54:
• Electrically conductive pipelines
• Other conductive components
• Protective conductors
• Functional earth electrodes
