Maintenance on electrical systems is done to detect problems before failure occurs. However, incorrect maintenance methods may cause larger malfunctions rather than correcting the system. Therefore, it is extremely important to know and avoid mistakes made during the maintenance process.

⚙️ 1. Working Without a Maintenance Plan

Random maintenance work may damage the integrity of the system. When planned maintenance is not performed, repeated failures occur in the same area.

Solution: Before each maintenance, a detailed plan should be prepared and a checklist should be created.

🔌 2. Intervening without cutting power

Operations performed under current put both employee safety and the device at risk. This situation creates a great danger, especially when working inside the panel.

Solution: The power must be completely cut off, warning labels must be placed and a locking system must be applied.

🔥 3. Bypassing Thermal Control

Checks made with a thermal camera determine the components that become heated inside the panel. Skipping this step increases the risk of possible fire and malfunction.

Solution: Thermal analysis should be performed at every maintenance and hot areas should be recorded.

🌍 4. Not Performing a Grounding Test

As the grounding value increases, the risk of shock and leakage current increases. Skipping this test poses a great danger, especially in industrial facilities.

Solution: Grounding measurement should be made at least once a year and the results should be reported.

⚡ 5. Ignoring Loose Links

Loosening of panel and terminal connections causes heating and short circuit. Installations that are not tightened regularly are at risk.

Solution: Connections should be checked periodically with a torque wrench.

🧰 6. Wrong Insurance Value Selection

Using a fuse that is not suitable for the circuit load will cause the system not to be protected in case of overcurrent. This error results in equipment malfunctions.

Solution: Fuses should be selected and tested according to the amount of load falling on the line.

📦 7. Neglecting Clipboard Cleaning

Dust, moisture and foreign objects cause insulation deterioration inside the panel. Over time, heat accumulation increases and relays fail.

Solution: Panels should be cleaned periodically and humidity control should be ensured.

💡 8. Inadequate Documentation

Failure to record maintenance operations makes it difficult to track fault history. This may lead to repeating the same mistake in the future.

Solution: Each maintenance operation should be reported in detail and archived digitally.

📋 9. Use of Non-Expert Personnel

Interventions made by inexperienced people damage the security of the system and may void the warranty coverage.

Solution: All maintenance work must be performed by certified electricians.
