C. Reduce construction labor
D. Increase electrical consumption
Correct Answer: B
Rationale: Electrical requirements are primarily intended to provide
protection against shock, fire, and other electrical hazards.
2. Which organization publishes the National Electrical Code (NEC)?
A. ICC
B. OSHA
C. NFPA
D. ASTM
Correct Answer: C
Rationale: The NEC is published by the National Fire Protection
Association as NFPA 70.
3. What does NEC stand for?
,A. National Electrical Construction
B. National Electrical Code
C. National Energy Code
D. National Engineering Code
Correct Answer: B
Rationale: NEC means National Electrical Code.
4. Which electrical inspector credential is designated E1 by ICC?
A. Commercial Electrical Inspector
B. Electrical Plans Examiner
C. Residential Electrical Inspector
D. Residential Mechanical Inspector
Correct Answer: C
Rationale: ICC designates E1 as the Residential Electrical Inspector
credential.
5. A conductor that carries current under normal operating conditions
is generally called a:
A. Grounding electrode
B. Current-carrying conductor
C. Bonding jumper
D. Ground rod
Correct Answer: B
Rationale: A current-carrying conductor is one that carries current
during normal operation.
6. What is the primary function of an overcurrent protective device?
,A. Increase voltage
B. Limit dangerous current conditions
C. Improve power factor
D. Increase conductor length
Correct Answer: B
Rationale: Fuses and circuit breakers protect conductors and
equipment from excessive current.
7. Which unit measures electrical current?

Rationale: Voltage is measured in volts.
10. Which formula represents Ohm's law?
A. P = I/R
B. V = IR
C. R = VI
D. I = VR
Correct Answer: B
Rationale: Ohm's law is V = I × R.
