1. A 120/240-volt single-phase dwelling service supplies a calculated load of
150 amperes. What is the minimum service disconnect rating permitted?
A. 100 amperes
B. 125 amperes
C. 150 amperes
D. 200 amperes
Answer: C. 150 amperes
The service disconnecting means must have a rating not less than the calculated
load.
2. A continuous load is calculated at 32 amperes. What is the minimum
ampacity required for the branch-circuit conductors?
A. 32 amperes
B. 35 amperes
C. 40 amperes
D. 45 amperes
Answer: C. 40 amperes
Continuous loads are generally multiplied by 125%. 32 × 1.25 = 40 amperes.
3. A 20-ampere, 120-volt branch circuit supplies four receptacles. What is the
maximum permitted rating of a single receptacle installed on this circuit?
A. 15 amperes
B. 20 amperes
C. 25 amperes
D. 30 amperes
Answer: B. 20 amperes
,Where a single receptacle is installed on an individual branch circuit, its rating
must not be less than the branch-circuit rating.
4. Which conductor is normally used as the grounded conductor in a 120/240-
volt single-phase system?
A. Green
B. Bare copper
C. White or gray
D. Orange
Answer: C. White or gray
The grounded circuit conductor is normally identified by white or gray insulation
or other permitted identification methods.
5. What is the maximum overcurrent protection generally permitted for 14
AWG copper conductors?
A. 15 amperes
B. 20 amperes
C. 25 amperes
D. 30 amperes
Answer: A. 15 amperes
14 AWG copper is generally limited to a 15-ampere overcurrent device.
6. A 10 AWG copper conductor has an allowable ampacity of 35 amperes
under the applicable temperature limitation. What is the largest standard
overcurrent device that may generally protect it when the next-size rule is
not applicable?
A. 30 amperes
B. 35 amperes
C. 40 amperes
D. 45 amperes
Answer: A. 30 amperes
,The overcurrent device cannot normally exceed the conductor ampacity, and 30
amperes is the applicable standard rating.
7. A 240-volt single-phase load draws 24 amperes. What is its power
consumption?
A. 2,880 W
B. 4,800 W
C. 5,760 W
D. 9,600 W
Answer: C. 5,760 W
Power = voltage × current. 240 × 24 = 5,760 watts.
8. A 120-volt load consumes 1,800 watts. What current does it draw?
A. 10 A
B. 12 A
C. 15 A
D. 20 A
Answer: C. 15 A
Current = power ÷ voltage. 1,800 ÷ 120 = 15 amperes.
9. What is the minimum number of 20-ampere small-appliance branch circuits
generally required for a dwelling kitchen?
A. One
B. Two
C. Three
D. Four
Answer: B. Two
At least two 20-ampere small-appliance branch circuits are generally required for
the specified dwelling kitchen loads.
, 10.Which type of protection is intended to protect people from electric shock
caused by ground-fault current?
A. AFCI
B. GFCI
C. Thermal overload
D. Surge protective device
Answer: B. GFCI
Ground-fault circuit-interrupters are designed to interrupt the circuit when a
dangerous imbalance of current is detected.
11.Which device is primarily intended to protect against arcing faults
associated with damaged wiring?
A. GFCI
B. AFCI
C. Disconnect switch
D. Thermal fuse
Answer: B. AFCI
Arc-fault circuit-interrupters are designed to detect and interrupt hazardous arcing
conditions.
12.A dwelling receptacle is installed within the required GFCI-protected
location near a sink. Which protection is generally required?
A. AFCI only
B. GFCI
C. Overload relay
D. Surge protection only
Answer: B. GFCI
Receptacles in locations specified by the NEC for GFCI protection must be
protected accordingly.
13.What is the primary purpose of bonding metal electrical equipment?
