Equipment leakage current
The Equipment Leakage Test measures the total leakage deriving from the Applied Parts, Enclosure and Mains Parts
combined to real earth.
The test is conducted with the protective earth connection interrupted to ensure the measurements are done under
worst conditions. As such, any earth leakage current will be measured as part of the enclosure (or touch) leakage.
Applied parts leakage shall be performed on both mains and battery power operating mode.
[Enclosure leakage test – mains power operating].
[Applied Parts leakage test – mains power operating].
[Applied Parts leakage test – battery power operating]
