7.6. Substitute leakage current (I

EA

)

Current that would flow through the interconnected active
conductors of the device (test object) and the protective
conductor or the touchable conductive parts at rated voltage and
rated frequency of the device.
This measuring method determines the leakage current without
mains voltage.
It is an alternative measuring method for determining protective
conductor current or touch current.

See also the measuring principle circuit under point 8.4.

7.7. Visual inspection

Testing in accordance with DIN VDE 0701-0702 requires a visual
inspection of the device. According to the standard, the devices
should be inspected for external defects (without opening the
device) and, as far as possible, for suitability to the place of
installation.
(More details are provided in the DIN VDE 0701-0702 standard).
