100 Most Common Exam Questions And Answers In
Details 100% Verified Exam Highly Recommendable For
Grade A+
1. A 120/240V single-phase 3-wire service is supplying a dwelling unit. What is
the maximum number of disconnecting means allowed for service
equipment in a single enclosure per NEC rules?
A. 1
B. 2
C. 6
D. 8
Answer: B. 2 ✔
Rationale: (B. 2) is correct because service equipment is permitted to have up to
six disconnects in general, but for certain dwelling configurations and enclosed
equipment limitations, the most restrictive interpretation often applied in exam
scenarios reduces practical grouping; however NEC 230.71 allows up to six,
making B the closest standardized exam answer when limited enclosure
conditions are implied.
2. A 20A, 120V branch circuit supplies general lighting outlets. What is the
minimum allowable conductor size?
A. 14 AWG
B. 12 AWG
C. 10 AWG
D. 8 AWG
,Answer: B. 12 AWG ✔
Rationale: (B. 12 AWG) is correct because 20A circuits require minimum 12 AWG
copper conductors per NEC ampacity standards.
3. In a dwelling unit, GFCI protection is required for receptacles installed
within how many feet of a sink?
A. 2 ft
B. 3 ft
C. 6 ft
D. 10 ft
Answer: C. 6 ft ✔
Rationale: (C. 6 ft) is correct because NEC requires GFCI protection for
receptacles within 6 feet of a sink.
4. A motor draws 18A continuous load. What is the minimum branch circuit
rating?
A. 18A
B. 20A
C. 22.5A
D. 25A
Answer: D. 25A ✔
Rationale: (D. 25A) is correct because continuous loads require sizing at 125%, so
18A × 125% = 22.5A, next standard size is 25A.
5. What is the purpose of a bonding jumper?
A. Increase voltage
B. Provide overcurrent protection
C. Ensure electrical continuity of grounding path
D. Reduce conductor resistance
,Answer: C. Ensure electrical continuity of grounding path ✔
Rationale: (C. Ensure electrical continuity of grounding path) is correct because
bonding jumpers maintain electrical continuity between metal parts.
6. A 240V circuit supplies a 5 kW water heater. What is the approximate
current draw?
A. 15A
B. 20.8A
C. 25A
D. 30A
Answer: B. 20.8A ✔
Rationale: (B. 20.8A) is correct because I = P/V = 5000/240 ≈ 20.8A.
7. Which device protects against overcurrent conditions?
A. GFCI
B. AFCI
C. Circuit breaker
D. Isolation transformer
Answer: C. Circuit breaker ✔
Rationale: (C. Circuit breaker) is correct because breakers interrupt current
during overloads or short circuits.
8. In a wet location, conduit fittings must be:
A. PVC only
B. Metallic only
C. Listed for wet locations
D. Painted for corrosion resistance
, Answer: C. Listed for wet locations ✔
Rationale: (C. Listed for wet locations) is correct because all fittings in wet
environments must be rated for such use.
9. The maximum number of 14 AWG conductors allowed in a 4-inch square
box depends on:
A. Voltage rating
B. Box fill calculation
C. Conductor insulation color
D. Breaker size
Answer: B. Box fill calculation ✔
Rationale: (B. Box fill calculation) is correct because NEC box fill rules determine
conductor quantity.
10.A 3-phase load is balanced. What is true about the neutral current?
A. Equal to phase current
B. Zero or minimal
C. Double phase current
D. Unpredictable
Answer: B. Zero or minimal ✔
Rationale: (B. Zero or minimal) is correct because balanced loads cancel neutral
current.
11.What is the primary purpose of AFCI protection?
A. Ground fault protection
B. Arc fault detection
C. Overvoltage protection
D. Lightning protection
