Industrial Panel Maintenance Checklist

A single loose connection in your main panel can halt your entire production line. Preventive maintenance is cheaper than emergency repairs.

Weekly Checks

• Visual Inspection: Look for any signs of soot, burn marks on breakers, or melted insulation.
• Strange Sounds: Listen for buzzing or humming noises from contactors (chattering).
• Indicator Lights: Ensure all Phase Indication lamps (R-Y-B) are glowing.
• Door Seal: Check that the panel door closes tightly to prevent dust entry.

Monthly Deep Clean (Power OFF Required)

• Tightening: Use a torque screwdriver to tighten all terminal screws. Heat cycles loosen them over time.
• Dust Removal: Use a vacuum cleaner (not blower) to remove dust. Dust can cause short circuits in humid weather.
• Thermal Scan: If available, use a thermal camera to find hotspots on busbars.
