IEC 60364-5-54:20 11涉及接地布置和保护导体，包括保护连接导体，以满足电气装置的安全性。第三版取消并取代了2002年出版的第二版，构成了技术修订。与上一版相比的主要变化如下: -澄清保护导体的定义； -改进了接地电极的机械特性的规格； -引入接地电极，用于防电击和防雷； -描述混凝土嵌入式基础接地电极和土壤嵌入式接地电极的附件。 根据IEC指南104，IEC 60364-5-54:2011具有基本安全出版物的地位。

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.
IEC 60364-5-54:2011 has the status of a basic safety publication in accordance with IEC Guide 104.
