This is directly from the ESA FAQ:
What is a "final inspection" and when does it take place?
This inspection is done after the electrical installation is complete. This means that all receptacles, switches, cover plates, lighting fixtures and permanently connected appliances are in place and the panel directory has been completed. All unused openings in panel boards or junction and outlet boxes shall be filled with suitable fillers. Where an appliance that is to be permanently connected is not yet on site, the cable shall be terminated in a junction box complete with a blank cover and the ends of the conductors shall be insulated with wire connectors or tape. Where permanent light fixtures are not yet on site, install temporary light fixtures or a blank cover on lighting outlet boxes. The final inspection shall be requested as soon as possible after completion of the electrical installation.
