C. Any metal rod
D. Painted for protection
Answer: A. Copper or copper-clad steel
Rationale: NEC 250.52 specifies materials for durability and conductivity in grounding
electrodes.
3. The purpose of a GFCI is to:
A. Protect against ground faults and prevent electric shock
B. Increase current flow
C. Regulate voltage
D. Control lighting
Answer: A. Protect against ground faults and prevent electric shock
Rationale: GFCIs monitor current imbalance and trip when leakage occurs to ground.
4. Maximum voltage drop allowed for branch circuits is:
A. 2%
B. 3%
C. 5%
D. 10%
,Answer: B. 3%
Rationale: NEC recommends 3% voltage drop to ensure proper equipment
performance and efficiency.
5. The color of equipment grounding conductors is:
A. Green or green with yellow stripe
B. Black
C. White
D. Red
Answer: A. Green or green with yellow stripe
Rationale: NEC 250.119 requires specific colors to identify grounding conductors for
safety.
6. Electrical boxes must be supported to:
A. Prevent movement of wiring and devices
B. Reduce voltage drop
C. Increase circuit capacity
D. None of the above
Answer: A. Prevent movement of wiring and devices
Rationale: Proper support ensures safety, prevents strain on conductors, and maintains
code compliance.
7. The minimum size copper conductor for a 20-ampere branch circuit is:
A. 12 AWG
B. 10 AWG
C. 14 AWG
D. 8 AWG
Answer: A. 12 AWG
Rationale: NEC 310.15 requires 12 AWG for 20-amp circuits to prevent overheating.

A. 53% of internal area
B. 40%
C. 31%
D. 50%
Answer: A. 53% of internal area
Rationale: NEC Chapter 9, Table 1 provides conduit fill limits to ensure proper wire
installation and heat dissipation.
10. The primary purpose of a neutral conductor is to:
A. Provide a return path for current
B. Carry only ground fault current
C. Increase voltage
D. Serve as equipment grounding
Answer: A. Provide a return path for current
Rationale: Neutral conductors complete the circuit back to the source in 120/240V
systems.
11. AFCI protection is required for:
A. Bedroom branch circuits
B. Kitchen circuits
C. Outdoor lighting
D. Service entrance only
Answer: A. Bedroom branch circuits
Rationale: AFCIs detect arc faults and prevent electrical fires in living spaces, NEC
210.12.
12. The minimum clearance above a residential swimming pool for overhead conductors
is:
A. 10 feet
B. 12 feet
C. 22 feet
D. 18 feet
Answer: C. 22 feet
Rationale: NEC 680.8 requires 22 feet for safety over pools to prevent electric shock.
