Yearly Main Switchboards Service Checklist

by Alan Conley, from the Community

Perform a thorough annual service of main switchboards with this step by step checklist aligned to Australian Standards and OHS requirements. Inspect panel exteriors and busbars, verify phase balance and loading, test main isolators and meters, replace indicator lamps, confirm protective relay settings, and check insulated phase barriers. Tighten neutral, earth and auxiliary terminations, remove contamination and moisture, and verify labels and warnings. Use infrared temperature checks, ensure switches are set to auto, clean enclosures, and complete a detailed service report.

Yearly Main Switchboard Service Checklist
Use this yearly main switchboard service checklist to maintain safe and reliable power distribution in line with Australian Standards, Codes of Practice, and OHS requirements. The template guides technicians through visual and mechanical checks of panels and enclosures, verification of phase balance and load, inspection of busbars, neutral, earth, and auxiliary terminations, and operation of main isolators. It includes accuracy checks of meters, review of protective relay settings against schematics, replacement of failed indicator lamps, and confirmation that insulated phase barriers and safety labels are intact. Technicians assess moisture ingress, remove contaminants, and perform infrared temperature scans on components and connections. The checklist concludes with ensuring switches are set to auto, cleaning the enclosure, and completing a service report for compliance and record keeping.

Hospital Switchboard Clean and Inspect
Use this checklist to clean and inspect hospital electrical switchboards and distribution boards. Verify clearances and exit access, confirm effective ventilation, and clean filters. Open panels to check conduits, connectors, wiring, fuses, relays, and terminations. Inspect for overheating, dust, corrosion, moisture, pest activity, and insulation damage. Check earth continuity and record neutral current. Test indicator lamps, seals, hinges, and labeling. Vacuum interiors, restore panels securely, and clean external surfaces. Record meter readings, note maximum demand, reset where required, and list any nonconformances and recommendations.

Energising Switchboards Inspection & Test Checklist
Streamline pre-energisation checks for electrical switchboards. This practical checklist guides electricians through safety and compliance steps: verifying no exposed live parts, correct earthing and bonding, protecting cable entries, consistent breaker orientation, and secure terminations. Record insulation resistance (meggar) and main earth results, check CT shorting links, confirm phase rotation, and set overloads to the single line diagram. Ensure labeling, access clearances, lockout and tagging, and placement of required notices. Capture approvals and certificates to meet AS/NZS 3000 requirements and document commissioning.

Electrical Cable Test Checklist
Use this cable test checklist to plan and record electrical pre commissioning and pre energization tests on installed cables and switchboards. Capture project and location details, confirm site readiness, and verify crew sign on. Log test equipment make and model, serial numbers, and calibration due dates for insulation testers, multimeters, and clamp meters. Document cable endpoints, select test voltages, and record insulation resistance results between phases, phase to neutral, and phase to earth, with guidance that values should be at least 1 Mohm. Perform continuity checks with phases bonded to neutral at one end and verify results meet 0.5 ohm criteria. Include tester battery and lead checks and confirm compliance with AS3000 before energization.
