FCC Technician Exam Question Of The Day (T0A01)

Q) Which is a commonly accepted value for the lowest voltage that can cause a dangerous electric shock?

A) 30 volts

NJ2X Notes:
Any voltage above 30V is commonly considered to be capable of delivering dangerous electric shock.  Low voltages can still be dangerous even if they're too low to directly cause shock injury. They may be enough to startle and cause an accident.
