Leakage Current; Ground Resistance Check - GE Giraffe Service Manual

3.8 Leakage Current

Use approved equipment and techniques to test the unit's leakage current and ground continuity. Follow the
directions supplied by the test equipment manufacturer to verify the following:
1. Less than 300 microamperes measured at any exposed metal surface for equipment rated at 120 VAC,
50/60 Hz.
2. Less than 500 microamperes measured at any exposed metal surface for equipment rated at 220 VAC,
50/60 Hz or 240 VAC, 50/60 Hz.

3.9 Ground Resistance Check

Use a electrical safety analyzer to measure the resistance between the ground pin on the line cord plug and
exposed metal of the electronic enclosure. The ground resistance must be less than 0.2 ohms.
