For the purposes of high voltage marine practice, what is the threshold voltage where all voltages below this value are considered low voltage?

A1.0 kV
B3.3 kV
C6.6 kV
D11 kV
AI Explanation

The correct answer is A) 1.0 kV. According to the National Electrical Code (NEC), any voltage below 1.0 kV is considered low voltage for the purposes of marine electrical systems. Voltages above 1.0 kV are considered high voltage and require specialized equipment, training, and safety precautions. The other options (B, C, and D) represent higher voltages that would be classified as high voltage, not low voltage, in the context of marine electrical systems.
