Test samples with protective conductor must have a proper and safe connection to all
accessible conductive parts that are connected to the protective connector and can be live in
the event of a fault [}page79].
The protective conductor resistance is composed of the following values:
• The resistance value between the connection point of the test sample up to all accessible
conductive parts of the test sample that are connected to the protective conductor,
• The transition resistances of all terminal and plug connections,
• the resistances of all connected extension and device connecting cables.
To determine the protective conductor resistance, you can select various testing currents.
• Testing current: 0.6A‑AC or 10A‑AC
• Test frequency: 50Hz
When exceeding the limit [}page111], it has to be checked whether other limits have to be
observed due to product standards or manufacturer specifications.
