Understanding what your tester is telling you is crucial. False readings from induced voltages, ghost voltages, or capacitive coupling can mislead even experienced technicians. Always cross-verify with additional testing methods when in doubt.

Mistake #9: Working on Live Circuits Unnecessarily

While some testing requires live circuits, many procedures can be performed on de-energized systems. The golden rule: if you don’t need it live, turn it off. Proper lockout/tagout procedures should always precede voltage testing.

Mistake #10: Inadequate Training and Competency

Perhaps the most critical mistake is assuming all electrical workers are competent in voltage testing. Regular training, certification updates, and practical assessments are essential for maintaining safety standards in the rapidly evolving UAE construction landscape.
