This main switchboard maintenance checklist supports safe, reliable building operations with structured 6 monthly and annual tasks. It guides teams to isolate hazards, inspect meters and bus ducts, measure outgoing circuit loads with a tong tester, and confirm protection settings. It covers visual condition checks, corrosion, housekeeping, and stock levels for fuses and indicator lamps. Annual actions include thermographic surveys, tightening bolted joints, primary current injection testing of air circuit breakers, cleaning interiors and ventilation, verifying IP ratings at cable entries, and checking manual changeover operation. The checklist also captures spare capacity measurements and ensures single line schematics are current.
