Preventive maintenance of electrical systems involves regular inspections, testing, and servicing to ensure safe, efficient operation and to prevent unexpected failures.By proactively addressing issues like loose connections, worn insulation, or overheating, preventive maintenance helps reduce risks of electrical shock, fire, and costly downtime. Key activities include checking voltage levels, inspecting insulation, cleaning components, and testing grounding systems.

This approach is especially valuable in high-use environments, where equipment reliability and safety are critical.Regular maintenance not only extends the life of electrical systems but also helps ensure compliance with safety standards, protecting both personnel and assets.
