IEC 60364-5-55:2011涵盖了低压发电机组的选择和安装以及作为固定装置一部分的灯具和照明装置的选择和安装的要求。第二版取消并取代了2001年出版的第一版及其修正案1(2001)和修正案2(2008)。与上一版相比的主要技术变化是: -将灯具连接到固定布线的附加要求； -修改关于固定灯具的要求； -包括用于连接用于直通布线和用于将照明器连接到电源的设备的替代解决方案； -撤回第556条，因为IEC 60364-5-56现在涵盖了该事项。

IEC 60364-5-55:2011 covers requirements for the selection and erection of low-voltage generating sets and for the selection and erection of luminaires and lighting installations intended to be part of the fixed installation. This second edition cancels and replaces the first edition, published in 2001, its Amendment 1 (2001) and its Amendment 2 (2008). The major technical changes with respect to the previous edition are:
- additional requirements for connection of luminaires to the fixed wiring;
- modification of requirements regarding the fixing of luminaires;
- inclusion of alternative solutions for connecting devices used for through wiring and for connection of luminaires to the supply;
- withdrawal of Clause 556, as IEC 60364-5-56 now covers this matter.
