When using Dale 600/601 or a similar test instrument, its power plug may be inserted into the wall outlet
and the equipment under test is plugged into the receptacle on the panel of the meter. This places the
meter in the grounding conductor and the current flowing from the case to ground will be indicated in
any of the current ranges. The maximum allowable limit for enclosure leakage current is shown in
Table 10-11 on page 10-22
10-8-5-3 Data Sheet for Enclosure Leakage Current
The test passes when all readings measure less than the value shown in Table 10-11 .
Record all data on the Ultrasound Inspection Certificate.
10-8-6 Earth Leakage Current Test
10-8-6-1 Definition
This test measures the current that would flow to a grounded person who touched accessible
protectively-earthed parts of equipment if the ground wire should break.
The meter is connected from accessible protectively-earthed parts of the equipment to ground.
Measurements should be made with power line polarity normal and reversed, and with the neutral open
and closed Record the highest reading.
