  1. An inspector finds that the cable running through holes drilled in the center of 2x4 studs is less than 1.25 inches from the edge of the stud face. What is required per NEC 300.4(A)(1)?

    Answer: A listed steel plate at least 1/16 inch thick must be installed to protect the cable

    NEC 300.4(A)(1) requires a steel plate of at least 1/16-inch thickness to protect cables where the edge of the hole is less than 1.25 inches from the nearest edge of the wood member.

  2. A residential inspection reveals a ceiling fan installed in a box marked 'Acceptable for Fan Support' with a weight rating of 35 lbs. The fan weighs 42 lbs. What is the required action?

    Answer: The box must be replaced with one rated for the actual fan weight

    NEC 314.27(C) requires fan-rated boxes to support the weight of the fan being installed; using a box with an insufficient weight rating is a code violation.

  3. What is the minimum wire size permitted for a 120V, 20A small appliance branch circuit in a kitchen, per NEC 210.19(A)?

    Answer: 12 AWG copper

    A 20A branch circuit requires conductors rated at least 20A; 12 AWG copper is the minimum size rated for 20A per NEC Table 310.16 at 60°C.

  4. Under NEC 410.10(D), luminaires installed in clothes closets must maintain specific clearance from storage areas. What is the minimum clearance required for a surface-mounted incandescent fixture?

    Answer: Incandescent fixtures are not permitted in closets

    NEC 410.16(A) prohibits pendant luminaires, incandescent luminaires with open or partially enclosed lamps, and incandescent luminaires of any type in clothes closets; only listed LED, fluorescent, or completely enclosed fixtures are permitted.

  5. A residential panel is located in a bathroom. Is this installation permitted under NEC 230.70(A)(1) and 240.24(E)?

    Answer: No, overcurrent devices cannot be located in bathrooms

    NEC 240.24(E) specifically prohibits overcurrent devices from being located in the bathrooms of dwelling units, guest rooms, or guest suites.

  6. What voltage is required between the two ungrounded conductors of a standard residential 240V split-phase service?

    Answer: 240 volts

    In a standard residential split-phase system, each ungrounded conductor carries 120V to neutral, and the two ungrounded conductors are 180 degrees out of phase, providing 240V between them for 240V appliances.

  7. Per NEC 338.10(B)(4)(a), NM cable used as service entrance cable must be kept free from exposure to physical damage and must be installed where?

    Answer: Only within a building, not outside any structure

    NM (nonmetallic sheathed) cable is not approved for outdoor or wet locations per NEC 334.10 and 338.10; it may only be used inside the structure after the service entrance conductors enter the building.
