A licensed electrician handles anything attached to the breaker panel or carrying line voltage (120V/240V). A standard residential service call begins with the panel: the electrician verifies the main breaker rating, looks for double-tapped breakers, checks for AFCI/GFCI compliance in the right rooms, and tests for proper grounding at the service drop. Outlet, switch, and fixture work is straightforward. Panel upgrades, sub-panel adds, EV-charger installs, and whole-house rewires require a permit, a load calculation (NEC Article 220), and an inspection by the local AHJ before the panel is energized.
