Open combined protective and neutral (PEN) conductor detection devices (OPDDs): OPDDs for use in electric vehicle charging applications for household and similar installations (IET 01:2024)

This Standard (IET 01:2024) includes definitions, requirements and tests for open PEN detection devices (OPDDs). During a protective earth neutral (PEN) fault, hazardous touch-voltages may occur at exposed-conductive-parts, including metallic parts of an electric vehicle (EV), connected to the supply PEN conductor by installation and equipment protective conductors.
