New York Electrical Contractor Licensing Exam
1. The National Electrical Code (NEC) is primarily concerned with
A. Energy efficiency
B. Electrical pricing
C. Fire and shock hazards
D. Building aesthetics
Answer: C
The NEC’s main objective is to protect people and property from hazards
arising from electricity, primarily fire and shock.
2. The standard frequency of alternating current in the United States is
A. 60 Hz
B. 50 Hz
C. 100 Hz
D. 30 Hz
Answer: A
U.S. electrical systems operate on 60 cycles per second (60 Hz).
3. The minimum burial depth for direct-buried UF cable under residential
driveways is
A. 12 inches
B. 18 inches
, C. 24 inches
D. 30 inches
Answer: C
NEC Table 300.5 requires a minimum of 24 inches for direct-buried cable
under residential driveways.
4. Ground-fault circuit interrupters (GFCIs) are designed to trip when the
current imbalance exceeds
A. 1 mA
B. 4–6 mA
C. 10 mA
D. 30 mA
Answer: B
GFCIs protect against ground faults by detecting current imbalances
greater than 4–6 mA.
5. In a 120/240V single-phase system, what is the voltage between the two
hot conductors?
A. 120V
B. 240V
C. 208V
D. 277V
Answer: B
The two hot legs in a single-phase system are 180 degrees apart,
producing 240V between them.
6. The color used for grounding conductors in the NEC is
A. White
B. Black
C. Green or bare
D. Blue
Answer: C
Green or bare conductors are always used for grounding to ensure safety
and identification.
7. The ampacity of conductors must be corrected when the ambient
temperature exceeds
, A. 25°C
B. 30°C
C. 35°C
D. 40°C
Answer: B
Per NEC Table 310.15(B)(1), ampacity corrections begin above 30°C
(86°F).
8. Which NEC article covers branch circuits?
A. 210
B. 220
C. 225
D. 240
Answer: A
Article 210 provides requirements for branch circuits, including ratings
and receptacle placement.
9. A 20-amp circuit requires a minimum conductor size of
A. 14 AWG
B. 12 AWG
C. 10 AWG
D. 8 AWG
Answer: B
Per NEC Table 310.16, 12 AWG copper is rated for 20 amps.
10.The neutral conductor in a 120/240V system carries
A. The sum of currents
B. The difference of currents
C. Zero current
D. Twice the current
Answer: B
The neutral carries only the unbalanced current—the difference between
the two hot legs.
11.The main bonding jumper connects
A. The equipment grounding conductor to the neutral
