,Q1. A 480V, 3-phase, 4-wire, wye-connected service has a calculated load of 800A per
phase. The grounded conductor is required to be sized to carry the maximum
unbalanced neutral current. What is the MINIMUM ampacity required for the
neutral conductor?
A. 400A
B. 800A
C. 693A
D. 1000A
Correct Answer: B. 800A
Rationale: For a wye-connected 3-phase, 4-wire system, the neutral carries the
unbalanced current, which can be up to the phase current. Since each phase is 800A, the
maximum unbalanced neutral current is 800A, so the neutral must have an ampacity of at
least 800A.
Why Wrong:
A - 400A would only be sufficient if the load were balanced and the neutral current
were reduced, but the maximum unbalanced condition requires full phase current.
C - 693A is the result of multiplying 800A by 0.866 (cos 30°), which is not the correct
method for sizing a neutral conductor.
D - 1000A is not supported by the Code; the neutral is not required to exceed the
phase conductor ampacity.
Reference: Canadian Electrical Code (CEC) Rule 4-024
Q2. In a Class I, Division 1 hazardous location, which wiring method is permitted for
a 480V, 3-phase motor circuit?
A. Rigid metal conduit (RMC) with threaded joints
B. Electrical metallic tubing (EMT) with compression fittings
C. Type MC cable with hermetically sealed fittings
D. Metal-clad cable with approved fittings
Correct Answer: A. Rigid metal conduit (RMC) with threaded joints
Rationale: Class I, Division 1 locations require threaded rigid metal conduit or
intermediate metal conduit (IMC) with threaded joints to contain explosions. EMT and MC
cables are not permitted in Division 1 because they do not provide the same level of
containment.
Why Wrong:
B - EMT is not permitted in Class I, Division 1 because it cannot contain an internal
explosion.
C - MC cable is not permitted in Division 1; it is only allowed in Division 2.
D - Metal-clad cable is not permitted in Division 1 for the same reason as MC cable.

Q3. A 120/240V, single-phase, 3-wire feeder supplies a panelboard with a calculated
load of 150A on each ungrounded conductor. The feeder is protected by a 150A
breaker. What is the MINIMUM size of the grounded (neutral) conductor?
A. No. 1/0 AWG copper
B. No. 2 AWG copper
C. No. 1 AWG copper
D. No. 3/0 AWG copper
Correct Answer: A. No. 1/0 AWG copper
Rationale: For a 120/240V single-phase system, the neutral carries the unbalanced
current, which is the difference between the two phase currents. With 150A on each phase,
the maximum unbalanced current is 150A. The neutral must have an ampacity of at least
150A, which is No. 1/0 AWG copper (150A at 75°C).
Why Wrong:
B - No. 2 AWG copper has an ampacity of 115A, which is less than the required
150A.
C - No. 1 AWG copper has an ampacity of 130A, which is less than 150A.
D - No. 3/0 AWG copper is larger than necessary; the minimum is No. 1/0.
Reference: CEC Table 2, Rule 4-024
Q4. A service entrance is installed in a building with a 1200A, 120/208V, 3-phase,
4-wire service. The service is fed by a utility transformer located 150 feet away. What
is the MINIMUM size of the grounding electrode conductor (GEC) required for a
concrete-encased electrode (Ufer) using 4 AWG copper?
A. No. 2 AWG copper
B. No. 4 AWG copper
C. No. 6 AWG copper
D. No. 8 AWG copper
Correct Answer: B. No. 4 AWG copper
Rationale: For a concrete-encased electrode (Ufer), the GEC is not required to be larger
than No. 4 AWG copper, regardless of the service size. This is a specific Code rule that
permits a No. 4 AWG copper conductor for a concrete-encased electrode.
Why Wrong:
A - No. 2 AWG copper is larger than the minimum allowed for a Ufer ground.
C - No. 6 AWG copper is smaller than the minimum required for a concrete-encased
electrode.
D - No. 8 AWG copper is too small for a Ufer ground.
