4.3.5. Leakage current and Power test
The purpose of this test is to determine the loss of L to N current into PE. Leakage
current is the difference between the current in L and N mains lines.
Regardless of whether the current leaks into the earth lead or an extra ground point, the
leakage test will show the true leakage current.
Also the Power consumption of the appliance is shown.
