Low Voltage Directive
Within the EU, the most important document for regulating the safety of electrical devices, apart from the EMC Directive, is the Low Voltage Directive (Directive 2006/95/EC). Save for a few exceptions, it covers "electrical equipment designed for use with a nominal voltage of between 50 and 1000 V for alternating current and between 75 and 1500 V for direct current".
The directive stipulates that the electrical equipment must be manufactured in such a way that it does not jeopardise the safety of people or domestic animals or place property at risk, assuming that it is installed and maintained properly and is used in accordance with its intended purpose
