Pre-Outage Distribution Board Inspection Checklist

This checklist guides electricians through pre- and post-outage inspections of distribution boards to ensure safe isolation and compliance with AS3000. It covers energized and de-energized testing, including 10-point voltage checks, phase rotation, insulation resistance, and polarity. Steps include lockout and tagout, earthing system verification including MEN and equipotential bonding, documentation of ratings and cable sizes, photos, and results. Post-outage tasks confirm updated labeling, re-testing, and switchboard load testing with current balance verification. Use it to standardize procedures and reduce risk during commissioning.
