7–3 ELECTRICAL SAFETY TESTS
The following tests are performed at the factory and should be performed at the site. These tests are: grounding
continuity, chassis leakage current, probe leakage current, and ECG leakage current. All measurements are

Note
No outlet tester can detect the condition where the Neutral (grounded supply) conductor and the
Grounding (protective earth) conductor are reversed. If later tests indicate high leakage currents,
this should be suspected as a possible cause and the outlet wiring should be visually inspected.
