Recommendable For Grade A+
1. Which of the following is the primary purpose of the National Electrical
Code (NEC)?
A. To design electrical appliances
B. To provide minimum safety requirements for electrical installations
C. To calculate electrical utility rates
D. To certify electrical manufacturers
Answer: B ✓
Rationale: The NEC establishes [minimum safety requirements for electrical
installations] to protect people and property from electrical hazards.
2. In a 120V circuit drawing 12A, what is the resistance?
A. 8 Ω
B. 10 Ω
C. 12 Ω
D. 14 Ω
Answer: B ✓
Rationale: Using Ohm’s Law, R = V ÷ I = 120 ÷ 12 = [10 Ω].
3. A GFCI device is designed to protect against:
A. Overvoltage
B. Short circuits
C. Ground faults and shock hazards
D. Arc flash only
,Answer: C ✓
Rationale: A GFCI detects imbalance in current flow and protects against [ground
faults and electrical shock hazards].
4. What is the minimum burial depth for PVC conduit under a residential
driveway per NEC (general rule)?
A. 6 inches
B. 12 inches
C. 18 inches
D. 24 inches
Answer: C ✓
Rationale: Typical NEC guidance requires at least [18 inches of cover for PVC
conduit under driveways].
5. Which color is typically used for equipment grounding conductors?
A. White
B. Green
C. Red
D. Black
Answer: B ✓
Rationale: Equipment grounding conductors are identified as [green or green with
yellow stripe].
6. A 240V heater draws 20A. What is its power consumption?
A. 2,400W
B. 4,800W
C. 3,600W
D. 5,000W
Answer: B ✓
Rationale: P = V × I = 240 × 20 = [4,800 watts].
7. What is the function of a circuit breaker?
A. Increase voltage
, B. Store energy
C. Protect against overcurrent
D. Convert AC to DC
Answer: C ✓
Rationale: A circuit breaker automatically disconnects power during [overcurrent
conditions].
8. Which conductor is typically considered the neutral in a 120/240V system?
A. Black
B. Red
C. White
D. Green
Answer: C ✓
Rationale: The neutral conductor is identified as [white or gray] in NEC standards.
9. What is the main purpose of grounding an electrical system?
A. Increase voltage stability
B. Provide a return path for normal current
C. Limit voltage during fault conditions
D. Reduce resistance in circuits
Answer: C ✓
Rationale: Grounding helps stabilize voltage and provides a safe path during [fault
conditions].
10.Which device protects against arc faults?
A. AFCI
B. GFCI
C. MCB
D. Fuse link
Answer: A ✓
Rationale: An AFCI detects dangerous arc conditions and protects against [arc
faults in wiring].
