Verified Exam Highly Recommendable For
Grade A+
1. A 120/240V single-phase system supplies a dwelling. What is the voltage
between one hot conductor and neutral?
A. 240V
B. 208V
C. 120V
D. 277V
✔ Answer: C [120V]
Rationale: This is a standard split-phase system where each ungrounded
conductor to neutral measures 120 volts.
2. According to NEC, the minimum clearance for overhead service conductors
above residential driveways is:
A. 10 ft
B. 12 ft
C. 15 ft
D. 18 ft
✔ Answer: C [15 ft]
Rationale: NEC requires 15 feet clearance over residential driveways for
safety from vehicle contact.
3. The purpose of a grounding electrode system is to:
A. Carry normal load current
B. Provide a low-resistance fault path
, C. Increase circuit voltage
D. Balance phase loads
✔ Answer: B [Provide a low-resistance fault path]
Rationale: Grounding electrodes help dissipate fault current safely to
earth.
4. What is the maximum number of 14 AWG copper conductors allowed in a
½-inch EMT conduit (without derating factors)?
A. 6
B. 9
C. 12
D. 16
✔ Answer: B [9]
Rationale: NEC conduit fill tables allow up to nine 14 AWG conductors in
½-inch EMT at 40% fill.
5. A 20A, 120V branch circuit is typically required to supply:
A. Lighting only
B. Bathroom receptacles
C. Kitchen small appliance circuits
D. HVAC compressor
✔ Answer: C [Kitchen small appliance circuits]

A. White
B. Green or bare copper
C. Red
D. Black
✔ Answer: B [Green or bare copper]
Rationale: Equipment grounding conductors must be green, green/yellow,
or bare.
, 7. A GFCI device is designed to protect against:
A. Overvoltage
B. Short circuits
C. Ground faults
D. Lightning strikes
✔ Answer: C [Ground faults]
Rationale: GFCIs detect leakage current to ground and trip quickly.
8. What is the required minimum burial depth for a PVC conduit under a
residential driveway?
A. 6 inches
B. 12 inches
C. 18 inches
D. 24 inches
✔ Answer: C [18 inches]
Rationale: NEC typically requires 18 inches cover for PVC under residential
driveways.
9. Which device protects against overcurrent conditions?
A. Switch
B. Transformer
C. Circuit breaker
D. Receptacle
✔ Answer: C [Circuit breaker]
Rationale: Circuit breakers interrupt current flow during overloads or
faults.
10.The function of a neutral conductor is to:
A. Carry fault current only
B. Carry unbalanced load current
C. Ground the system
D. Increase voltage
✔ Answer: B [Carry unbalanced load current]
