1. According to the National Electrical Code (NEC), what is the
primary purpose of the Code?
A. To reduce construction costs
B. To establish minimum standards for electrical safety
C. To maximize energy efficiency
D. To replace local building codes
Answer: B. To establish minimum standards for electrical safety
Rationale: The NEC is intended to provide practical safeguarding of
persons and property from hazards arising from the use of electricity.
It establishes minimum safety requirements rather than design
specifications or energy efficiency standards.
2. Which NEC chapter generally covers wiring and protection?
,A. Chapter 1
B. Chapter 2
C. Chapter 5
D. Chapter 9
Rationale: NEC Chapter 2 addresses Wiring and Protection, including
branch circuits, feeders, overcurrent protection, grounding, and
related topics essential to safe electrical installations.
3. What is the minimum working space depth required in front of
electrical equipment operating at 150 volts to ground under
Condition 1?
A. 24 inches
B. 36 inches
C. 42 inches
D. 48 inches
Rationale: NEC 110.26 requires a minimum working depth of 3 feet (36
inches) for Condition 1 where exposed live parts are on one side and
no grounded parts are opposite.
4. A branch circuit is best defined as:
,A. Conductors between the utility transformer and service equipment
B. Conductors between the service drop and meter
C. Conductors between the final overcurrent device and the outlets
served
D. Conductors between feeders and transformers
Rationale: The NEC defines a branch circuit as the conductors between
the final overcurrent protective device and the outlets or loads they
supply.
5. Which conductor is intentionally grounded?
A. Equipment grounding conductor
B. Bonding jumper
C. Grounding electrode conductor
D. Grounded conductor
Rationale: The grounded conductor, commonly called the neutral, is
intentionally connected to ground as part of the electrical system.
6. What device is intended to open a circuit automatically upon an
overcurrent?
, A. Disconnect switch
B. Relay
C. Circuit breaker
D. Contactor
Rationale: Circuit breakers automatically interrupt current during
overloads or short circuits to protect conductors and equipment.
7. What color insulation is typically used for an equipment grounding
conductor?
A. Black
B. Red
C. White
D. Green or bare
Rationale: The NEC identifies equipment grounding conductors by
green insulation, green with yellow stripes, or bare copper.
8. Which type of conduit provides the greatest mechanical
protection?
A. EMT
B. FMC
