When there's too much leakage
current …
AC/DC Fails
Where applicable, check the AC/DC adapter and its cable.
Replace a new one if any portion is defective.
Chassis Fails
Check the ground on the power cord and plug for continuity.
Ensure the ground is not broken, frayed, or intermittent. Replace
any defective part.
Where applicable, tighten all grounds. Ensure star washers are
under all ground studs.
Inspect wiring for bad crimps, poor connections, or damage.
Test the wall outlet; verify it is grounded and is free of other
wiring abnormalities. Notify the user or owner to correct any
deviations. As a work around, check the other outlets to see if
they could be used instead.
NOTE: No outlet tester can detect the condition where the white neutral
wire and the green grounding wire 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. If reversed wiring is observed, it is the customers
responsibility to have the condition corrected by qualified
personnel.
