Domain 4: Services

Question 1

A 45 kVA, 480V primary, single-phase transformer has a primary FLC of 93.75A. At 125%, the calculated OCPD is 117.2A. What is the correct standard size primary OCPD?

  1. 100 amperes
  2. 110 amperes
  3. 125 amperes
  4. 150 amperes
Show answer & explanation

Correct answer: C - 125 amperes

Question 2

How many neutral-to-ground bonding points are permitted for a separately derived system?

  1. None - SDSs do not require grounding
  2. One bonding point only
  3. Two - one at the source and one at the first disconnect
  4. Unlimited, at each downstream panel
Show answer & explanation

Correct answer: B - One bonding point only

Domain 5: Load Calculations and Demand Factors

Question 3

A dwelling has a total general lighting, small-appliance, and laundry load of 10,500 VA. After applying Table 220.42 demand factors, the demand load is:

  1. 3,000 + (7,500 × 0.35) = 5,625 VA
  2. 10,500 × 0.35 = 3,675 VA
  3. 10,500 × 0.75 = 7,875 VA
  4. 3,000 + (7,500 × 0.50) = 6,750 VA
Show answer & explanation

Correct answer: A - 3,000 + (7,500 × 0.35) = 5,625 VA

Question 4

A dwelling has one range rated at 14 kW. Using Table 220.55, the demand load is calculated as:

  1. 8 kW (no adjustment needed)
  2. 8 kW × 1.10 = 8.8 kW
  3. 8 kW × 1.15 = 9.2 kW
  4. 14 kW at 80% = 11.2 kW
Show answer & explanation

Correct answer: B - 8 kW × 1.10 = 8.8 kW

Question 5

Using VD = 2KID/CM, what is the maximum one-way distance for a 120V, 20A circuit on 12 AWG copper (K=12.9, CM=6,530) with a 3% voltage drop limit (3.6V)?

  1. 72 feet
  2. 91 feet
  3. 109 feet
  4. 144 feet
Show answer & explanation

Correct answer: B - 91 feet

Domain 6: Motors and Motor Circuits

Question 6

A motor nameplate reads: 10 HP, 460V, 3-phase, FLA 13.5A, SF 1.15. For conductor sizing, the electrician uses:

  1. 13.5A from the nameplate
  2. 14A from Table 430.250
  3. 17.5A (125% of nameplate)
  4. 16.875A (125% of nameplate)
Show answer & explanation

Correct answer: B - 14A from Table 430.250

Question 7

Three motors on a common feeder: 20 HP (27A), 10 HP (14A), and 5 HP (7.6A), all 460V, 3-phase. The minimum feeder conductor ampacity is:

  1. 48.6 amperes
  2. 55.35 amperes
  3. 60.75 amperes
  4. 72.90 amperes
Show answer & explanation

Correct answer: B - 55.35 amperes

Domain 7: Overcurrent Protection

Question 8

Can the next standard size rule (240.4(B)) be used to round up to a 25A breaker for 14 AWG copper (15A ampacity)?

  1. Yes, rounding up is always permitted
  2. No, 240.4(D) limits 14 AWG to 15A maximum and overrides 240.4(B)
  3. Yes, but only with THHN insulation
  4. No, but a 20A breaker would be acceptable
Show answer & explanation

Correct answer: B - No, 240.4(D) limits 14 AWG to 15A maximum and overrides 240.4(B)

Domain 8: Hazardous (Classified) Locations

Question 9

A fire pump service must NOT have a disconnecting means that can be opened:

  1. By the building owner
  2. By the fire department
  3. Automatically (such as by overcurrent or ground fault)
  4. By a licensed electrician during maintenance
Show answer & explanation

Correct answer: C - Automatically (such as by overcurrent or ground fault)

Domain 9: Solar Photovoltaic (PV) Systems

Question 10

A PV module has an Isc of 9.5 amperes. The minimum conductor ampacity for the PV source circuit is closest to:

  1. 9.5 amperes
  2. 11.9 amperes
  3. 14.8 amperes
  4. 19.0 amperes
Show answer & explanation

Correct answer: C - 14.8 amperes
