Q1.
A commercial building's service entrance uses parallel conductors. Per the NEC, which
requirement governs the installation of parallel conductors to ensure equal current
sharing and prevent inductive heating?
A. All parallel conductors must have the B. Parallel conductors must be of the same
same length, ampacity, and insulation type, size and length, and each set must be
and be terminated in the same manner. installed in separate conduits to reduce skin
effect.
C. Parallel conductors are permitted only if D. Parallel conductors must be connected at
they are protected by a single overcurrent both ends to the same bus and must be of
device and are not longer than 50 feet. the same material, size, and insulation.
Correct: A - All parallel conductors must have the same length, ampacity, and insulation
type, and be terminated in the same manner.
Rationale:NEC 310.10(H) requires parallel conductors to be the same length, material,
cross-sectional area, insulation type, and terminated in the same manner to ensure equal
current division. Option B is wrong because separate conduits can cause unequal impedance.
Option C is wrong because there is no length limit. Option D is incomplete as it misses the
equal length and termination requirements.
Q2.
During a rough-in inspection of a dwelling unit, you observe that NM cable is run through
holes in wood framing. What is the minimum distance required from the edge of the hole
to the nearest edge of the framing member, and what protection is needed if this distance
is not met?
A. 1 inch; a metal nail plate at least 1/16 B. 1.25 inches; a steel plate at least 1/16
inch thick is required. inch thick is required.
C. 2 inches; a plastic bushing is required. D. 1.5 inches; no protection is needed if the
cable is stapled within 12 inches.
Correct: B - 1.25 inches; a steel plate at least 1/16 inch thick is required.
Rationale:NEC 300.4(D) requires that cables run through holes in framing be at least 1.25
inches from the nearest edge. If not, a steel plate at least 1/16 inch thick must protect the
cable. Option A is incorrect because the distance is 1.25 inches, not 1 inch. Option C is wrong
because 2 inches is not the standard. Option D is wrong because the distance is 1.25 inches
and a plate is required regardless of stapling.

Q3.
A three-phase, 4-wire, 208Y/120V service supplies a commercial kitchen. The calculated
load is 150 kVA. What is the minimum size copper service conductors (THHN, 75°C
terminals) required, and what is the minimum size grounding electrode conductor
required if connected to a concrete-encased electrode?
A. 3/0 AWG copper; 4 AWG copper. B. 4/0 AWG copper; 2 AWG copper.
C. 250 kcmil copper; 6 AWG copper. D. 350 kcmil copper; 4 AWG copper.
Correct: B - 4/0 AWG copper; 2 AWG copper.
Rationale:The service load is 150 kVA at 208V three-phase: I = 150,000 / (208 × "3) "H 416 A.
Per NEC 310.16, 4/0 AWG copper at 75°C has an ampacity of 230 A; however, for service
conductors, the 83% rule (NEC 230.42(B)) allows 4/0 for 400 A service. For a
concrete-encased electrode, NEC 250.66(B) requires a minimum of 4 AWG copper, but 2
AWG is typical for larger services. Option B is correct. Option A is undersized. Option C and
D are oversized for the 83% rule.
Q4.
A fire pump is supplied by a dedicated feeder from a separate service. According to NEC
Article 695, which of the following is a required overcurrent protection arrangement for the
fire pump feeder?
A. It must have a single overcurrent device B. It must be protected against overloads
sized to protect the feeder conductors. but not short circuits.
C. It must have a disconnecting means that D. It must be protected by a fire pump
is lockable in the closed position and rated controller that provides both overload and
for the locked-rotor current. short-circuit protection.
Correct: C - It must have a disconnecting means that is lockable in the closed position and
rated for the locked-rotor current.
Rationale:NEC 695.4(B) requires the fire pump disconnecting means to be lockable in the
closed position and rated to carry the locked-rotor current. Overload protection is prohibited
(695.4(B)(1)), but short-circuit protection is required (695.4(B)(2)). Option A is wrong because
overload protection is not allowed. Option B is wrong because short-circuit protection is
required. Option D is wrong because the controller provides overload protection, not
short-circuit.
Q5.
In a hazardous location classified as Class I, Division 2, you are installing a motor control
center. Which of the following wiring methods is permitted for the branch circuits?
