  1. When must an electrical inspector reference the NEC edition that was adopted by the local jurisdiction rather than the most current published edition?

    Answer: Always — inspectors enforce the adopted edition, not the latest

    Inspectors enforce the NEC edition formally adopted by the local Authority Having Jurisdiction (AHJ), which may lag behind the latest published edition.

  2. Under NEC 230.54, service entrance cables used with a weatherhead must be arranged so that water cannot enter the service entrance equipment. This is accomplished by:

    Answer: Forming a drip loop in the conductors

    NEC 230.54(F) requires service conductors to be arranged with a drip loop to prevent water from following the conductors into service equipment.

  3. According to NEC Article 100, what does the term 'Authority Having Jurisdiction' (AHJ) mean?

    Answer: The organization, office, or individual responsible for enforcing the code

    The AHJ is defined in NEC Article 100 as the organization, office, or individual responsible for enforcing the requirements of a code or standard.

  4. Which NEC article covers the installation of emergency systems such as those found in hospitals and places of assembly?

    Answer: Article 700

    NEC Article 700 covers emergency systems that supply power to lighting and power circuits essential for safety during normal power outages.

  5. An electrical inspector finds that a panelboard has a 'split bus' design. Under NEC 408.36, how many overcurrent devices may supply the lighting and appliance bus without a main disconnect in this design?

    Answer: 6

    NEC 408.36(B) permits up to 6 overcurrent devices to supply a lighting and appliance bus section in a split-bus panelboard without requiring an individual main disconnect.

  6. Under NEC 250.52, which of the following is NOT an acceptable grounding electrode?

    Answer: Underground gas piping systems

    NEC 250.52(B)(1) explicitly prohibits underground gas piping systems from being used as grounding electrodes due to explosion risk.

  7. When the NEC requires conductors to be 'identified' as grounded (neutral) conductors, which colors are acceptable for conductors 6 AWG or smaller?

    Answer: White or gray

    NEC 200.6(A) requires grounded conductors 6 AWG or smaller to be identified by a continuous white or gray outer finish.
