When Jennifer dislodges the power box, it short circuits and begins arcing over several inches. However, regular household power is 110/220 volts (the 220 being two independent 110-volt feeds). Under normal conditions, it takes approximately 1000 volts to arc one inch. Therefore, the voltage on the power box would have to be around 3-4000 volts in order to arc that far. Household power does not have the voltage necessary to produce a 3 to 4-inch arc.
