  1. During an inspection, the inspector notices the main electrical panel is located in a bathroom. What is the concern?

    Answer: Electrical panels are prohibited in bathrooms due to shock hazard from moisture

    Electrical panels are prohibited in bathrooms by NEC 240.24(E) because moisture creates a severe shock hazard near energized equipment.

  2. A homeowner has installed PVC (Schedule 40) drain pipe for the vent stack above the roofline. What should the inspector note?

    Answer: PVC may degrade from UV exposure above the roofline and should be noted

    Standard white PVC is not UV-stabilized and will become brittle and fail when exposed to sunlight above the roofline.

  3. What minimum clearance is required between a gas-fired furnace and combustible materials in the side/front?

    Answer: Clearances vary by manufacturer listing and must be verified on the unit's label

    Clearances to combustibles for furnaces are set by the manufacturer and listed on the appliance label, not by a single universal standard.

  4. An inspector observes aluminum wiring connected to a standard (non-CO/ALR rated) outlet in a 1970s home. What is the hazard?

    Answer: Connections between aluminum wire and non-rated devices can loosen and arc, creating a fire risk

    Aluminum expands and contracts more than copper; when connected to non-CO/ALR devices, the connections loosen over time, causing arcing and potential fires.

  5. What is the purpose of a condensate neutralizer on a high-efficiency condensing furnace?

    Answer: To raise the pH of acidic condensate before it enters the drain system

    Condensing furnaces produce acidic condensate (pH 2-4) that can corrode metal drain pipes; a neutralizer raises the pH to safe levels.

  6. Which of the following is a reportable deficiency for a gas appliance flue in a home inspection?

    Answer: The flue has a visible separation at a joint inside the utility room

    A separated flue joint can allow combustion gases including carbon monoxide to spill into living spaces, which is a serious safety hazard.

  7. What does AFCI protection in a circuit breaker guard against?

    Answer: Arcing faults caused by damaged or deteriorated wiring

    Arc Fault Circuit Interrupters detect dangerous arcing in wiring — a common cause of electrical fires — and interrupt the circuit.
