1. A Texas journeyman electrician is installing branch circuits in a
commercial office. According to the National Electrical Code
(NEC), a branch circuit is best defined as:
A. Conductors between the service equipment and the utility transformer
B. Conductors between the final overcurrent device protecting the circuit
and the outlets
C. Conductors between the meter and service disconnect
D. Conductors between the grounding electrode and equipment
grounding conductor
Answer: B. Conductors between the final overcurrent device
protecting the circuit and the outlets
Rationale: An NEC branch circuit consists of the circuit conductors
between the final overcurrent protective device and the outlets. This is a
fundamental definition every journeyman electrician must know.
2. A continuous load is expected to operate for:
A. 30 minutes or more
B. 1 hour or more
C. 3 hours or more
D. 8 hours or more
1
,Answer: C. 3 hours or more
Rationale: The NEC defines a continuous load as one expected to run
for three hours or longer. Conductors and overcurrent devices supplying
continuous loads are generally sized at 125%.
3. A 40-amp continuous load requires a minimum branch-circuit
rating of:
A. 40 amps
B. 45 amps
C. 50 amps
D. 60 amps
Answer: C. 50 amps
Rationale: 40 A × 125% = 50 A. Continuous loads require branch
circuits rated not less than 125% of the continuous load.
4. Which conductor has the lowest electrical resistance?
A. Aluminum
B. Copper
C. Steel
D. Brass
Answer: B. Copper
Rationale: Copper has significantly lower resistance than aluminum
and is the preferred conductor material where high conductivity is
desired.
2
, 5. The purpose of grounding electrical systems is primarily to:
A. Increase voltage
B. Improve conductor insulation
C. Stabilize system voltage and provide a path for fault current
D. Reduce current demand
Answer: C. Stabilize system voltage and provide a path for fault
current
Rationale: Grounding stabilizes voltage to earth and facilitates
operation of overcurrent protective devices during ground faults.
6. Which NEC chapter primarily contains wiring methods?
A. Chapter 1
B. Chapter 2
C. Chapter 3
D. Chapter 5
Answer: C. Chapter 3
Rationale: Chapter 3 covers wiring methods including raceways,
cables, boxes, fittings, and conductor installation requirements.
7. A 120-volt branch circuit supplying receptacles in a dwelling
kitchen requires:
A. AFCI only
B. GFCI only
C. Both AFCI and GFCI protection
3
, D. Neither AFCI nor GFCI protection
Answer: C. Both AFCI and GFCI protection
Rationale: Kitchen receptacles in modern dwelling installations require
both AFCI and GFCI protection under current NEC provisions.
8. Which raceway provides the greatest mechanical protection?
A. EMT
B. PVC Schedule 40
C. Flexible Metal Conduit
D. Rigid Metal Conduit
Answer: D. Rigid Metal Conduit
Rationale: Rigid Metal Conduit (RMC) offers the highest level of
physical protection and corrosion resistance.
9. The NEC requires electrical equipment to be installed according
to:
A. Utility preference
B. Manufacturer's instructions
C. Contractor experience
D. Inspector recommendations only
Answer: B. Manufacturer's instructions
Rationale: Equipment must be installed and used in accordance with its
listing and labeling, including manufacturer instructions.
