What is the impact of neglecting maintenance on electrical safety?

• A. It reduces the risk of electrical hazards.
• B. It increases the risk of electrical hazards.
• C. It has no impact on hazards.
• D. It improves fault detection.

Answer: (B)

Regular maintenance keeps electrical systems in safe condition. When maintenance is neglected, wear, damage, and misalignment can progress unchecked, raising the likelihood that a fault becomes dangerous. Insulation can degrade, cables and connectors can loosen or corrode, and protective devices may drift out of calibration or fail to operate when needed. These conditions increase the risk of electric shock, arc flash, short circuits, and fires. Maintenance activities like visual inspections, thermal imaging, insulation testing, cleaning, tightening connections, replacing worn parts, and verifying grounding and trip settings help catch problems before they lead to harm. So, neglecting maintenance does not reduce risk or improve fault detection; it increases hazards and reduces the ability to detect and mitigate faults.
