1
Ground electrode tests precautions.
Reduced the hazards associated with handling test leads by wearing
gloves and dielectrically rated footwear.
Exposed test leads and electrodes are isolated from workers and
the general public prior.
Short test periods assured and all test leads promptly removed
after the test is completed.
Remote probes and test leads are under continuous observation.
Ungrounded ends of test leads parallel an energized line mitigated
by the physical orientation of test leads, grounding, or both.

2
Surge arrester ground continuity tests precautions.
The base of the surge arrester can approach line potential. Never
disconnect the ground of a surge arrester.
Extremely high, short-duration lightning or switching currents can
be discharged into the ground.
A system fault can occur if a surge arrester fails during testing.

3
Neutral and shield wire ground tests procedures.
Disconnecting neutral and shield wires can generate hazardous
voltages.
Hazard can occur whether the line is energized or not, due to
current flow through the interconnected shield wires.

Equipment neutral ground test precautions.
High voltages can occur if neutrals are disconnected from energized
equipment.
