Below are a few questions from your upcoming PSI state exam:

  1. What would be the calculated the voltage drop on the #6 AWG copper conductors that serve a 15 HP, 480 V three-phase motor? (Assume the voltage source and the load are 150 feet apart installed in rigid metal conduit.)
    • Correct Answer: NEC – Table 430.250, Chapter 9 Table 8 (Conductor Properties), and Voltage Drop formula. See calculation steps below.
      1. Per Table 430.450 the FLC for the 15 HP 480 V motor is 21 amperes.
      2. Per Chapter 9 Table 8 the #6 AWG Circular mils is 26240.
      3. Use the Voltage Drop Formula, Vd = (1.732 x K x Length x Ampacity) / kcmil, Vd = (1.732 x 12.9 x 150 feet x 21 amps) / 26240 = 2.68 Volts.
  2. What is the minimum required feeder tap conductor size for a circuit protected by an 800 ampere OCP device, where the length of the tap conductors is 20 feet, using copper THWN wire?
    • Correct Answer: NEC – 240.21(B)(2)(1) Therefore, calculate; 800 amperes / 3 = 266 amperes, then use Table 310.15(B)(16) 75-degree C (THWN) column to size the feeder tap as 300 kcmil.
  3. The ampere rating of a feeder that supplies a continuous lighting load and a motor load shall be how many amperes when the lighting load is equivalent to 39 amperes and the motor load is equivalent to 24 amperes?
    • Correct Answer: 430.22, and 600.5(B) Therefore, calculate the total load by: 39 amperes + 24 amperes = 63 amperes, then multiply by 125%. 63 amperes x 1.25 = 78.75 amperes.

The NEC Codebook and all reference materials are all provided by PSI at the exam testing location. Do NOT bring your personal NEC, but do bring two valid forms of identification.
