What does a frayed cord indicate in electrical safety?

1. Need for grounding equipment

2. Proper insulation of wires

3. Existence of broken bones

4. Presence of exposed live wires

The correct answer is: Presence of exposed live wires

A frayed cord in electrical safety is a critical indicator of potential hazards, primarily signaling the presence of exposed live wires. When the insulation of a cord becomes damaged through wear and tear, it exposes the conductive wires inside, which can lead to electric shock or short circuits if touched or if they come into contact with conductive materials. This condition necessitates immediate attention to prevent accidents and ensure safety. In contrast, the other options do not accurately describe the implications of a frayed cord. The need for grounding equipment relates to electrical systems that require grounding to prevent overload or shocks, which is not directly indicated by fraying. Proper insulation of wires signifies that the cord is intact and safe, opposing the situation with a frayed cord. Lastly, the existence of broken bones is unrelated to electrical components and does not pertain to electrical safety measures. Therefore, identifying the frayed cord correctly points to the danger posed by exposed live wires, underscoring the necessity for prompt remediation.
