Break the AC charger supply check into verifiable tasks that cover at least the site's existing power supply, the vehicle's onboard charger capability, and equipment power, grounding and installation approval, and state who delivers each one. Before installing an AC charger, confirm single- or three-phase supply, the vehicle's onboard charger and the site approval; the equipment's rated power cannot be taken as the vehicle's charging power. Before handover, confirm that the site's existing power supply is logged and the vehicle's onboard charger capability is backed by documentation; re-confirm with both parties when equipment power, grounding and installation approval changes. On completion, the person responsible for AC charger supply checks signs off, records the dates of the documents used, and notes any exceptions that must be cleared before the next step.
