27. Contact with any energized electrical system conductor is potentially hazardous and precautions should be taken to prevent exposure. With all other factors considered equal (such as voltage, conducting path through the body and the duration of contact), contact with an energized electrical system conductor of which system type would produce the most damaging effect?
Contact with energized electrical systems is hazardous. Among DC, 60 Hz AC, and 10 kHz AC systems, 60 Hz AC is most damaging because it most efficiently disrupts the heart and nervous system at lower currents, given equal voltage, conducting path, and contact time.
