  1. A contractor installs a commercial fire alarm system panel in an electrical room and places it 12 inches from an existing panelboard. What NEC concern should the inspector raise?

    Answer: Fire alarm panels must not reduce the required working space in front of electrical equipment per NEC 110.26

    NEC 110.26(A) working space requirements must be maintained; installing equipment that encroaches on the required 3-foot depth in front of a panelboard is a violation.

  2. Which PPE is mandatory when performing infrared thermography on energized electrical equipment with panels open?

    Answer: Arc-rated face shield, arc-rated gloves, and arc-rated clothing appropriate for the incident energy level

    NFPA 70E requires arc-rated PPE appropriate for the incident energy level whenever working on or near energized equipment with covers removed, including thermography.

  3. During inspection of a commercial kitchen, an inspector finds 120V receptacles within 6 feet of a sink without GFCI protection. According to NEC 210.8(B), this is:

    Answer: A violation; GFCI protection is required for all receptacles in commercial kitchens

    NEC 210.8(B)(2) requires GFCI protection for all receptacles in commercial kitchens regardless of distance from water sources.

  4. A safety sign at a commercial electrical room reads 'DANGER – HIGH VOLTAGE'. According to ANSI Z535, the word 'DANGER' indicates:

    Answer: An imminently hazardous situation that, if not avoided, will result in death or serious injury

    ANSI Z535 defines DANGER as the signal word for imminently hazardous situations that will result in death or serious injury if not avoided.

  5. An E2 inspector finds that a commercial building's electrical service equipment has no field-applied arc flash label. Under NFPA 70E 130.5(H), the owner is required to:

    Answer: Perform an arc flash hazard analysis and label the equipment before work begins

    NFPA 70E 130.5(H) requires equipment to be field-marked with arc flash hazard information based on an engineering study before energized work is performed.

  6. A qualified electrician working on an energized 208V panel uses rubber insulating gloves rated at Class 0. What is the maximum use voltage for Class 0 gloves?

    Answer: 1,000V AC

    ASTM F496 and NFPA 70E classify Class 0 rubber insulating gloves for a maximum use voltage of 1,000V AC.

  7. Under NEC 110.16, arc flash hazard warning labels are required on which commercial electrical equipment?

    Answer: Switchboards, switchgear, panelboards, industrial control panels, and motor control centers likely to require examination while energized

    NEC 110.16 mandates arc flash warning labels on switchboards, switchgear, panelboards, industrial control panels, and MCCs likely to require energized work.
