1. Which of the following is the maximum allowable ampacity of a 12
AWG copper conductor in a residential branch circuit?
A. 15 amps
B. 20 amps
C. 25 amps
D. 30 amps
Rationale: 12 AWG copper conductors are rated for 20 amps under
normal conditions according to NEC Table 310.15(B)(16).
2. The minimum clearance for overhead service conductors above a
residential driveway is:
A. 10 feet
B. 12 feet
C. 12.5 feet
D. 15 feet
Rationale: NEC 230.24 requires a minimum of 12.5 feet clearance
over residential driveways for safety.
3. Which device is required to protect personnel from electrical shock in
wet locations?
A. Circuit breaker
B. Ground-fault circuit interrupter (GFCI)
C. Surge protector
D. Arc-fault circuit interrupter (AFCI)
, Rationale: GFCIs are designed to detect ground faults and protect
against electric shock, especially in wet locations.
4. When sizing a feeder for continuous load, the NEC requires the
ampacity to be at least:
A. 80% of the load
B. 90% of the load
C. 125% of the load
D. 150% of the load
Rationale: NEC 210.19(A)(1) requires that conductors supplying
continuous loads be sized at 125% of the continuous load.
5. The main purpose of bonding in an electrical system is to:
A. Increase voltage
B. Ensure a low-impedance path to ground
C. Reduce resistance in neutral conductors
D. Prevent power loss
Rationale: Bonding connects metal parts to ground, ensuring a safe
path for fault currents to prevent electric shock.
6. The NEC requires receptacles in bathrooms to be:
A. Non-polarized
B. GFCI protected
C. 15-amp only
D. AFCI protected
Rationale: NEC 210.8(A)(1) mandates GFCI protection for all
receptacles in bathrooms.
7. Which type of conduit is suitable for underground installation?
A. EMT
B. PVC Schedule 40
C. IMC
D. RMC above ground only
Rationale: PVC Schedule 40 is approved for direct burial underground
installations per NEC 352.10.
8. The voltage rating of a branch-circuit overcurrent protection device
should not be less than:
A. The nominal voltage of the circuit
B. 75% of the load voltage
, C. Twice the line voltage
D. 50% of the load voltage
Rationale: NEC 240.4 ensures overcurrent devices are rated for the
circuit voltage to safely interrupt overcurrents.
9. Aluminum conductors require special consideration because:
A. They have higher resistance and expand more than copper
B. They are prone to oxidation and require anti-oxidant paste
C. They can’t be used in branch circuits
D. They are less conductive than steel
Rationale: Aluminum oxidizes, which increases resistance at
connections; anti-oxidant compounds prevent this.
10. The minimum size copper equipment grounding conductor for a
20-ampere branch circuit is:
A. 14 AWG
B. 12 AWG
C. 10 AWG
D. 8 AWG
Rationale: NEC Table 250.122 specifies 12 AWG copper as the
minimum for 20-amp circuits.
11. AFCI protection is required in which of the following areas?
A. Bathrooms
B. Kitchens
C. Bedrooms
D. Garages
Rationale: NEC 210.12(A) requires AFCI protection for all dwelling
unit bedrooms to prevent fires caused by arcing.
12. Which of the following best describes a multi-wire branch
circuit?
A. Circuit with two hots sharing a neutral
B. Two or more ungrounded conductors sharing a neutral
C. Circuit with separate neutral for each hot
D. Parallel circuits feeding the same device
Rationale: A multi-wire branch circuit shares a neutral between
ungrounded conductors, allowing efficient current handling.
