  1. What is the minimum required height for a wall-mounted outdoor receptacle cover plate when the cover is in the closed position on a residential dwelling?

    Answer: 12 inches above grade

    NEC 210.52(F) requires outdoor receptacles to be readily accessible, and covers must be rated in-use (weatherproof) when in use; however, local amendments often require a minimum of 12 inches above finished grade.

    Answer: Bathroom receptacle circuit

    NEC 210.12 requires AFCI protection for all 120V, 15/20A branch circuits in dwelling units except bathrooms, which instead require GFCI protection under 210.8(A)(1).

  3. An inspector finds a junction box in an attic covered with insulation and no cover plate installed. What is the primary code violation?

    Answer: All junction boxes must remain accessible with a cover

    NEC 314.29 requires all boxes to be accessible without removing any part of the building, and NEC 314.28 requires covers on all junction boxes.

  4. What is the maximum length of a flexible cord permitted to connect a permanently installed dishwasher to an outlet under NEC 422.16(B)(2)?

    Answer: 6 feet

    NEC 422.16(B)(2) permits dishwashers to be cord-and-plug connected with a cord no longer than 6 feet and no shorter than 3 feet.

  5. During a residential inspection, a smoke alarm is found installed on a wall 18 inches below the ceiling. Is this compliant with NFPA 72?

    Answer: No, wall alarms must be within 4 to 12 inches from the ceiling

    NFPA 72 requires wall-mounted smoke alarms to be installed with the top of the alarm between 4 and 12 inches from the ceiling.

  6. Which NEC section governs the clearance requirements for electrical equipment working space in front of a residential panelboard?

    Answer: NEC 110.26

    NEC 110.26 specifies working space requirements including a minimum depth of 3 feet, minimum width of 30 inches or the width of the equipment, and minimum headroom of 6.5 feet.

  7. A homeowner has installed a 240V/40A range receptacle using 10 AWG copper wire on a 40A breaker. What is wrong with this installation?

    Answer: 10 AWG copper is only rated for 30A at 60°C terminals

    10 AWG copper wire is rated for 30A per NEC Table 310.16 at 60°C, so using it on a 40A overcurrent device violates the ampacity rules.
