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.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
