Bibliography

IEC 60364-5-54:2011 addresses the earthing arrangements and protective conductors including protective bonding conductors in order to satisfy the safety of the electrical installation. This third edition cancels and replaces the second edition, published in 2002, and constitutes a technical revision. The main changes with respect to the previous edition are listed below:
- clarification of the definition of protective conductor;
- improved specification of mechanical characteristics of the earth electrode;
- introduction of earth electrode for protection against electric shock and lighting protection;
- annexes describing concrete-embedded foundation earth electrodes and soil-embedded earth electrode.
