  1. Under NEC Section 210.8, GFCI protection is required for all 125-volt, 15- and 20-ampere receptacles installed in which outdoor location?

    Answer: All outdoor receptacles accessible to grade level

    NEC 210.8(A)(3) requires GFCI protection for all 125V, 15 and 20A outdoor receptacles that are accessible to grade level.

  2. A landscape lighting conductor shows a resistance of 2 ohms for a 100-foot run. Applying Ohm's Law, what voltage drop would occur at 2 amps of load?

    Answer: 4 volts

    V = I × R; 2 amps × 2 ohms = 4 volts of drop across the run.

  3. What is the primary safety hazard addressed by using equipment listed for 'wet locations' rather than 'damp locations' in a landscape lighting installation?

    Answer: Risk of electric shock from water ingress

    Wet-location listed equipment prevents water ingress that could cause electric shock hazards in fully exposed outdoor environments.

  4. An inspector finds landscape lighting wire nuts used on direct burial splices without an enclosure. This is a violation because:

    Answer: Splices must be in a Listed enclosure suitable for the location

    NEC 300.15 requires splices and taps to be made in Listed enclosures suitable for the location, regardless of voltage level.

  5. A Listed landscape lighting transformer is rated 300VA. What is the maximum wattage load that should be connected to it?

    Answer: 240 watts (80% of rating)

    Best practice and many manufacturer guidelines recommend loading a transformer to no more than 80% of its rated VA to prevent overheating and extend service life.

  6. What is the purpose of the equipotential bonding grid required around swimming pools under NEC 680.26?

    Answer: To eliminate voltage differences that could cause shock in the water

    Equipotential bonding eliminates voltage gradients in and around the pool that could cause electric shock even without a complete circuit to ground.

  7. When must a landscape lighting installation in a residential setting obtain an electrical permit?

    Answer: Whenever required by the local Authority Having Jurisdiction (AHJ)

    Permit requirements are determined by the local AHJ; some jurisdictions require permits for all electrical work regardless of voltage.
