Read the first 7 Electrical Systems Inspection flashcards as text

  1. What is the minimum clearance required between the top of a residential electrical panel and the ceiling?

    Answer: 6 feet

    NEC requires a minimum of 6 feet of headroom above electrical panels to allow safe working space.

  2. Which condition is indicated when a home inspector finds aluminum wiring connected directly to a standard duplex receptacle rated for copper only?

    Answer: A potential fire hazard due to galvanic incompatibility

    Aluminum wiring connected to copper-only devices creates a galvanic reaction that can cause overheating and fire hazard.

  3. A home inspector observes double-tapping on a circuit breaker. What does this mean?

    Answer: Two wires are connected to a single breaker terminal not rated for it

    Double-tapping occurs when two conductors are connected to a breaker terminal designed for only one, creating a potential loose connection and fire hazard.

  4. What does a home inspector look for when inspecting knob-and-tube wiring?

    Answer: Signs of insulation contact, splices, or modifications

    Knob-and-tube wiring must be inspected for improper modifications, contact with insulation (fire hazard), and unauthorized splices.

  5. Which of the following is a reportable deficiency when inspecting a sub-panel in a detached garage?

    Answer: The neutral and ground conductors are bonded together at the sub-panel

    In a sub-panel, the neutral and ground must be kept separate; bonding them together creates a shock hazard on the grounding path.

  6. A home inspector finds an ungrounded three-prong receptacle in a 1955 home. What is the safest acceptable remedy according to the NEC?

    Answer: Install a GFCI receptacle and label it 'No Equipment Ground'

    The NEC permits replacing ungrounded receptacles with GFCI devices labeled 'No Equipment Ground' as a code-compliant alternative to rewiring.

  7. When inspecting a service entrance, a home inspector notes the service drop conductors are less than 10 feet above a driveway. What is the concern?

    Answer: A vehicle could contact the conductors, creating an electrocution hazard

    The NEC requires service conductors to be at least 10 feet above driveways to prevent vehicles from contacting energized wires.
