  1. NEC 110.26 specifies dedicated working space in front of electrical equipment. For equipment rated 601–2500V, what is the minimum depth of working space (Condition 1)?

    Answer: 4 feet

    NEC Table 110.26(A)(1) requires 4 feet of working space depth for equipment rated 601–2500V under Condition 1.

  2. Which section of the NEC addresses the ampacity correction factors for conductors installed in ambient temperatures above 30°C (86°F)?

    Answer: NEC 310.15(B)(1)

    NEC 310.15(B)(1) provides temperature correction factors applied when ambient temperature exceeds the base 30°C used in the ampacity tables.

  3. Under NEC 230.70, the service disconnecting means for a building or structure must be located:

    Answer: Outside the building or nearest the point of entrance

    NEC 230.70(A)(1) requires the service disconnect to be located outside the building or inside nearest the point of entry of the service conductors.

  4. Per NEC 517.13, patient care spaces in health care facilities require a redundant equipment grounding path. This is accomplished by using:

    Answer: Both metallic wiring methods and an insulated EGC

    NEC 517.13 requires both a metallic wiring method (EMT, MC cable, etc.) and a separate insulated equipment grounding conductor for redundancy in patient care areas.

  5. What is the maximum number of overcurrent devices, excluding the main breaker, permitted in a lighting and appliance branch-circuit panelboard per NEC 408.36?

    Answer: 42

    NEC 408.36 limits lighting and appliance branch-circuit panelboards to a maximum of 42 overcurrent devices (poles).

  6. According to NEC 695.6, fire pump controllers must be located or protected so that they are not exposed to:

    Answer: Possible water damage

    NEC 695.6(D) requires fire pump controllers to be protected from possible water intrusion to ensure reliable operation during a fire emergency.

  7. Under NEC 240.4(D), small conductors (No. 14 AWG copper) on a 15-amp circuit must be protected at a maximum of:

    Answer: 15 amps

    NEC 240.4(D)(3) limits overcurrent protection for No. 14 AWG copper conductors to a maximum of 15 amps.
