The above figure illustrates the current wiring of standard

The above figure illustrates the current wiring of standard 120 VAC receptacles in the United States. Which of the following statements about the safety ground wire is false? A) Under normal (non-fault) conditions the voltage on the neutral wire is the same as the voltage on the safety around wire. B) The satin ground wire is usually green in color. C) Under normal (non-fault) conditions the current in the neutral wire is the same as the current in the safety ground wire. D. A purpose of the safety ground wire is to keep metallic surfaces of electrical devices at earth ground potential. E) A purpose of the safety ground wire is to trip the circuit breaker if the hot wire short-circuits to a metallic surface.

Solution

Option C also correct but the purpose of using safety ground wire is to trip circuit breaker when ever hot wire short circuits in matallic surface.

So the absolute answer is option E
