Marine Electrical Systems USCG Question #1101 (Set 37)

Which of the following voltage testers would be associated with high quality, be safe to use, and minimize the electric shock hazard?

Official USCG Answer & Rule Citation

Correct Answer: Option A — a voltage tester with a high input impedance and a voltage rating higher than any expected measured voltages

High input impedance voltage testers draw minimal current during measurement, protecting the meter and technician while providing safety ratings exceeding expected circuit voltages, thus minimizing electrical shock and arc flash risks.
