  1. A technician is working inside an electrical panel with the main breaker off but the utility conductors still energized. What is the status of the line-side lugs?

    Answer: Still energized because utility conductors are not controlled by the main breaker

    Line-side lugs remain energized at utility voltage even with the main breaker off, because energy flows directly from the meter to those lugs.

  2. NEC 250.122 requires equipment grounding conductors to be sized based on:

    Answer: The rating of the overcurrent device protecting the circuit

    NEC 250.122 sizes equipment grounding conductors (EGC) per Table 250.122, based on the overcurrent protective device rating.

  3. What is the purpose of a equipotential bonding grid in a swimming pool area?

    Answer: To eliminate voltage differences between metal parts that could shock bathers

    Equipotential bonding connects all metal parts at the same electrical potential, preventing dangerous voltage gradients that could electrocute swimmers.

  4. According to NFPA 70E, which boundary is defined as the distance from an energized part within which a person could receive a second-degree burn from an arc flash?

    Answer: Arc flash boundary

    The arc flash boundary is the distance at which incident energy equals 1.2 cal/cm², the onset of second-degree burn threshold.

  5. A 20A, 120V circuit feeds a continuous load. Per NEC 210.20, the circuit's overcurrent device must be rated at least:

    Answer: 25A

    NEC 210.20(A) requires the overcurrent device to be rated at 125% of the continuous load current (20A × 1.25 = 25A).

  6. Which NEC section requires tamper-resistant receptacles in all 125V, 15A and 20A receptacles in dwelling unit areas accessible to children?

    Answer: NEC 406.12

    NEC 406.12 requires tamper-resistant receptacles in dwelling units to protect children from inserting objects into energized slots.

  7. When performing an infrared (IR) thermography scan for hot spots in an electrical panel, panels must typically be:

    Answer: Energized and under load with covers removed or panels open

    IR thermography requires panels to be energized and under load to reveal thermal anomalies; loose connections only heat up under current flow.
