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 B — a voltage tester with a high input impedance and a voltage rating higher than any expected measured voltages
High input impedance meters draw minimal current through test leads, reducing arc flash potential. A voltage rating exceeding any expected system voltage ensures meter integrity against transient overvoltages, complying with safe electrical testing protocols outlined in IEEE 45 and NFPA 70E guidelines.
