Earth terminal of power outlet
Enclosure leakage current measurement conditions
It is necessary to measure the enclosure leakage current under two
conditions: normal condition and single fault condition.
How to reproduce a single fault condition
You can reproduce a single fault condition by connecting the conversion
plug to the power outlet with the earth wire not connected.
Acceptance standards
Normal condition
0.1 mA or less
Single fault condition
0.5 mA or less
