  1. Which of the following best describes arc-fault circuit interrupters (AFCIs) and where they are required?

    Answer: AFCI breakers are required in most living areas of new residential construction per NEC

    NEC now requires AFCI protection in virtually all living areas of new residential construction including bedrooms, living rooms, kitchens, and hallways.

  2. During electrical rough-in inspection, what is the minimum box fill volume required for a single 12 AWG conductor entering a box?

    Answer: 2.25 cubic inches

    Per NEC Table 314.16(B), each 12 AWG conductor requires 2.25 cubic inches of box fill volume to prevent overheating and overcrowding.

  3. What is the inspection criterion for determining if a neutral conductor is properly sized for a feeder?

    Answer: The neutral must be sized to carry the maximum unbalanced load from the line conductors

    The neutral conductor must be sized to handle the maximum unbalanced load between phase conductors, which may be smaller than phase conductors in balanced three-phase systems.

  4. When should a construction inspector require an electrical permit and inspection for temporary power during construction?

    Answer: Temporary power installations always require a permit and inspection like permanent installations

    Temporary electrical installations for construction require permits and inspection under NEC Article 590 just as permanent installations do.

  5. What is the primary concern an inspector should have when observing aluminum wiring connections at outlets and switches?

    Answer: Aluminum wire requires CO/ALR rated devices to prevent loose connections due to thermal expansion differences

    Aluminum expands and contracts at a different rate than copper, requiring CO/ALR rated devices specifically designed for aluminum connections to prevent fire hazards.

  6. When inspecting a commercial electrical installation, what document must be available on-site to verify equipment is listed and labeled?

    Answer: Product listing from a nationally recognized testing laboratory (NRTL) such as UL or ETL

    All electrical equipment must bear a listing mark from an NRTL such as UL, ETL, or CSA, confirming it has been tested to applicable safety standards.
