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

• 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. achieved using surge protection devices
to create additional equipotential bonding system
for all supply lines the low-voltage system and in-
formation technology. This includes the functional equipoten-
tial bonding cable per DIN 18014 and the metal
main reinforcement reinforced concrete.
• Metal cable shields
Additional protective equipotential bonding
The lightning protection equipotential bonding an
extension the general protective equipotential bond-
ing. potentially explosive areas, where explicit
normative requirements apply, additional protective
equipotential bonding must implemented.
For installations under special environmental condi-
tions, e.1 Equipotential bonding systems
Correct use equipotential bonding systems pre-
vents dangerous touch voltages between system com-
ponents.
The bodies all fixed (non-portable) equipment the
immediate vicinity the place installation that can
be touched the same time must connected with
all extraneous conductive parts that can touched at
the same time.g.TBS

Protective equipotential bonding
All extraneous conductive parts routed into the build-
ing must connected with one another order to
prevent differences potential.g
