American Institute of Inspectors Standards of Practice
9 – SYSTEM: ELECTRICAL
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:
- Low voltage systems except to report the presence of solenoid-type lighting systems.
- Alarm systems, security system devices, heat detectors or carbon monoxide detectors.
- Intercom telephone, security, TV, lightning arrestors or other ancillary wiring that is not part of the primary electrical distribution system.
- Built-in vacuum equipment.
- Measurement of amperage, voltage or impedance in any electrical system, device or appliance.
