10-6-5 Enclosure Leakage Current Test
10-6-5-1 Definition
This test measures the current that would flow in a grounded person who touched accessible non-
protectively-earthed parts of equipment if the ground wire were to break. The test verifies the isolation
of the power line from the chassis.
The meter is connected from accessible non-protectively-earthed parts of the case to ground.
Measurements should be made with the ground open and closed, with power line polarity normal and
reversed, and with the neutral open and closed. Record the highest reading.
