Which of the following outcomes results from neglecting periodic maintenance of electrical systems?

Neglecting periodic maintenance of electrical systems significantly increases the risk of electrical failures. Regular maintenance is crucial for identifying potential issues before they escalate into major problems. It helps in ensuring that all components are functioning correctly, which minimizes the chances of unexpected breakdowns.

When maintenance is ignored, wear and tear on equipment can go unnoticed, leading to malfunctions that might cause the system to fail entirely. This can result in costly repairs, downtime, and even safety hazards. Therefore, the outcome of disregarding routine maintenance is a higher likelihood of electrical failures, which can disrupt operations and require more extensive repairs down the line.

In contrast, improved system efficiency, enhanced longevity of equipment, and lower operational costs are all associated with proper maintenance practices. Regular upkeep generally leads to better performance, extends the life of the equipment, and can help in reducing costs in the long run by preventing major failures and optimizing energy use.
