Essential Energy Service Mains Onsite Post Audit

This field audit checklist supports the Essential Energy Bulk Service Mains Replacement Program. It guides auditors through customer communication, switchboard cleaning and asbestos controls, equipment sealing, phase sequencing and recording, and isolation of main switches, circuit breakers, and fuses. It verifies correct termination clamps, shear-off connections, neutral bonding, drip loops, and compliance with Essential Energy construction standards and NSW Service Installation Rules. It includes checks for new mains boxes and isolation devices, removal of redundant hardware, vegetation clearing, and leaving the site safe. It also captures destructive connection testing plus no‑load and with‑load voltage and current readings across phases, neutral, and main earth.
