What electrical hazard involves damaged wiring?

• A. Short circuits
• B. Frayed cords
• C. Overloads
• D. Ground faults

Answer: (B)

Damaged wiring creates an immediate danger because the insulating cover wears away, exposing live conductors. Frayed cords are a prime example: the outer jacket looks worn, and the copper inside can be touched or can short against metal, raising the risk of electric shock and fire. Other electrical problems like a short circuit, an overload, or a ground fault describe different failure modes—short circuits involve a direct connection between conductors causing a surge, an overload means the circuit is carrying more current than it can safely handle, and a ground fault is current leaking to the ground due to insulation failure or faulty equipment. The hazard tied most directly to visibly damaged wiring is frayed cords, since the exposure of conductors is the clearest route to shock or ignition. If you see a frayed cord, stop using it and replace it to prevent harm.
