JOURNEYMAN ELECTRICIAN TEST QUESTIONS AND
ANSWERS SET A+
✔✔Single-conductor cable such as _____ and single-conductor cable listed and
identified as solar photovoltaic (PV) wire are permitted for use in PV source circuits
within the PV array. - ✔✔USE-2
690 covers the wiring methods specified for use on solar photovoltaic (PV) systems
arrays.
indicates open, single-conductors such as Type USE-2 and single-conductor cable
listed and identified as PV wire are permitted foruse in PV source circuits within the PV
array.
These conductors are evaluated and listed for use where exposed to sunlight and wet
conditions.
✔✔For dwelling units, GFCI protection is required for all single-phase, 125-volt, 15- and
20-ampere receptacles installed within six (6) feet of the top inside edge of the bowl of
sinks located in _____.
a. laundry rooms
b. bathrooms
c. garages
d. all of these areas - ✔✔All of these areas
no matter what the location or room in a dwelling, where the 15- or 20-ampere, 125-volt
eceptacles are installed within six (6) feet from the top inside edge of the bowl of the
sink, GFCI protection must be provided to prevent a ground-fault shock hazard.
✔✔For a building or structure where the meter enclosure is adjacent to the service
disconnecting means, it is permitted to ground the meter enclosure to the _____
, conductor on the load side of the service disconnect if ground-fault protection is not
provided. - ✔✔Grounded
The meter enclosure to be grounded by connection on the load side of the service
disconnect where (1) no ground-fault protection is installed, (2) the meter enclosure is
adjacent to the service disconnecting means, and (3) the grounded service conductor is
not smaller than the size specified
✔✔In a dwelling unit where a 125-volt, 15- or 20-ampere receptacle is located under the
counter for an in-sink waste disposer, the receptacle must be provided with _____.
a. AFCI protection only
b. GFCI protection only
c. both AFCI and GFCI protection
d. neither AFCI nor GFCI protection - ✔✔Both AFCI and GFCI protection
Because of the presence of water and grounded surfaces that contributes to a potential
shock hazard
any 125-volt, 15- or 20-ampere receptacle installed within six (6) feet of a sink is
required to be GFCI protected. Section 210.12(A) verifies AFCI protection is required for
all 120-volt, 15- or 20-ampere branch-circuits that supply outlets in kitchens in
dwellings.AFCI devices are designed to determine resistance to unwanted tripping due
to the presence of arcing that occurs in utilization equipment under normal operating
conditions or to a loading condition that closely mimics an arcing fault.
✔✔Where a 125-volt, 15-ampere receptacle is connected to a 120-volt branch circuit
supplying two (2) or more receptacles or outlets, the maximum permitted cord-and-plug-
connected load to the receptacle is _____. - ✔✔12 amperes
the general rules regarding branch circuits. Branch circuit and receptacle ratings are
addressed in Part II of Article 210. To prevent overheating receptacles, a receptacle
shall not supply a total cord-and-plug-connected load in excess of the maximum
specified in Table 21(B)(2), where connected to a branch circuit supplying multiple
receptables or other outlets. This table shows a 15-ampere rated receptacle may carry
a maximum cord-and-plug-connected load of 12 amperes under this condition.
✔✔In industrial establishments only, when a 200-ampere rated busway is tapped from a
600-ampere rated busway, what is the maximum permitted length of the 200-ampere
busway where overcurrent protection is not provided for the 200-ampere busway? -
✔✔50 ft
the permitted installation of busways. For busways in industrial establishments only,
providing overcurrent protection at the point where the busway size is changed is not
required if the busway having the smaller ampacity does not exceed fifty (50) feet in
