WebProtective devices capable of responding to overloads and short circuit, such as circuit breakers, have been available for a number of years. Newer technologies now provide enhanced protection from arcing or ground-faults, which may prevent fires or shock. WebAn electric shock can result in anything from a slight tingling sensation to immediate cardiac arrest. The severity depends on the following: • the amount of current flowing through the body, • the current’s path through the body, • the length of time the body remains in the circuit, and • the current’s frequency.
