Which of the following statements regarding permits and inspections is most accurate?

Accepted Answer

A permit is always required for a service upgrade, and a final inspection by the AHJ is mandatory before the new service can be energized.

Accepted Answer

Before any insulation or drywall is installed, while all wiring is still exposed for visual inspection.

Answer

After all devices (receptacles, switches, light fixtures) are installed and the system is ready for final power.
