9.1 The inspector SHALL observe and report on:

  • Service entrance conductor type and condition.
  • Service equipment, grounding equipment, main over-current device, and main and downstream distribution panels (subpanels) [downstream panels are to be in inspected areas].
  • Amperage and voltage ratings of the service.
  • Branch circuit conductors, their over-current devices, and the compatibility of their ampacity and voltages.
  • The operation of a representative number of installed ceiling fans, lighting fixtures, switches and receptacles located inside the house and attached garage, and on the dwelling exterior walls.
  • The polarity and grounding of all accessible outlets.
  • The presence of GFI outlets within six feet of interior plumbing fixtures, in the garage or carport, unfinished concrete floor basements and attached to the exterior of the inspected structure.
  • The operation of Ground Fault Circuit Interrupters (GFCI) test button.
  • The operation of Arc Fault Circuit Interrupter (AFCI) breaker test button.

9.2 The inspector SHALL identify and describe:

  • Service amperage and voltage.
  • Service entry conductor material.
  • Service type as being overhead or underground.
  • Location of electrical main disconnect.
  • Location and description of electrical downstream panels (if located in an inspected area).
  • The presence of any 110-volt solid aluminum branch circuit wiring.

9.3 The inspector is NOT required to:

  • Insert any tool, probe or testing device inside the electrical panels.
  • Test or operate any over-current device except Ground Fault Circuit Interrupters (GFCI) and Arc Fault Circuit Interrupter (GFCI) breakers using the installed test buttons.
  • Dismantle any electrical device or control other than to remove the covers of the main and auxiliary distribution panels.
  • Operate electrical systems or components that are disconnected or switched off at the main electrical panel.
  • Disconnect any energized system or appliance.
  • Move furnishings or storage to gain access to the electrical panel.
  • Evaluate the electrical panel if insufficient clearance does not permit safe access.
  • Examine de-icing equipment, private or emergency electrical supply sources, including but not limited to: generators, windmills, photovoltaic solar collectors, or battery or electrical storage facilities.
  • Observe or report on:
  1. Low voltage systems except to report the presence of solenoid-type lighting systems.
  2. Alarm systems, security system devices, heat detectors or carbon monoxide detectors.
  3. Intercom telephone, security, TV, lightning arrestors or other ancillary wiring that is not part of the primary electrical distribution system.
  4. Built-in vacuum equipment.
  5. Measurement of amperage, voltage or impedance in any electrical system, device or appliance.
