1. What is the primary purpose of the National Electrical Code
(NEC)?
A. To reduce construction costs
B. To establish minimum standards for electrical safety
C. To regulate utility company rates
D. To replace local building codes
Answer: B. To establish minimum standards for electrical safety
Rationale: The NEC establishes minimum requirements for safe
electrical installations to protect people and property from electrical
hazards. While local jurisdictions may adopt additional requirements,
the NEC serves as the national baseline for electrical safety.
, 2. Which NEC article covers general requirements for branch
circuits?
A. Article 100
B. Article 210
C. Article 250
D. Article 300
Answer: B. Article 210
Rationale: NEC Article 210 provides requirements for branch circuits,
including ratings, receptacle spacing, GFCI protection, AFCI protection,
and required outlets in dwelling units.
3. What is the maximum continuous load that may be placed on a
20-amp branch circuit?
A. 20 amps
B. 18 amps
C. 16 amps
D. 15 amps
Answer: C. 16 amps
,Rationale: Continuous loads are limited to 80% of the overcurrent
device rating unless equipment is listed for 100% operation. Eighty
percent of 20 amps equals 16 amps.
4. Which conductor color is commonly used to identify the grounded
(neutral) conductor?
A. Green
B. White
C. Red
D. Orange
Answer: B. White
Rationale: The NEC requires grounded conductors to be identified by
white or gray insulation or by three continuous white stripes on other
than green insulation.
5. Equipment grounding conductors are intended primarily to:
A. Carry normal load current
B. Stabilize voltage
C. Provide a low-impedance path for fault current
D. Reduce energy consumption
, Answer: C. Provide a low-impedance path for fault current
Rationale: Equipment grounding conductors facilitate the operation of
overcurrent devices by providing an effective ground-fault current
path, helping clear faults quickly.
6. What is the minimum working space depth for equipment
operating at 0 to 150 volts to ground under Condition 1?
A. 24 inches
B. 30 inches
C. 36 inches
D. 48 inches
Answer: C. 36 inches
Rationale: NEC 110.26 generally requires a minimum working space
depth of 3 feet (36 inches) for equipment operating at 0–150 volts to
ground under Condition 1.
7. EMT stands for:
A. Electrical Metallic Tubing
B. Electrical Mechanical Tube
C. Engineered Metal Track
