WebThe leakage test on Class II equipment is referred to as a Touch Current Test. Many test instruments also have a substitute or alternative leakage test. The substitute leakage test applies a reduced ac voltage, typically 40 - 60 Vac, between the line and neutral joined together and the earth conductor, or test lead for Class II equipment.
