, Q1. A commercial kitchen in Hawaii requires a new 60A, 208V, 3-phase load. The
calculated load with demand factors is 45A. The branch circuit will run through an
ambient temperature of 45°C and the conductors are THHN/THWN-2 rated 90°C.
What is the minimum copper conductor size (AWG/kcmil) required, considering all
applicable correction factors?
A. 6 AWG
B. 4 AWG
C. 3 AWG
D. 2 AWG
Correct Answer: C. 3 AWG
Rationale: The load is continuous, so the circuit must be rated at 125% of the 45A load,
yielding 56.25A. The ambient correction factor for 45°C for 90°C-rated conductors is
0.87. Thus, the conductor must have an ampacity of at least 56.25A / 0.87 = 64.66A at
90°C. A 3 AWG THHN/THWN-2 has a 90°C ampacity of 110A, which after correction
gives 95.7A, exceeding 64.66A. 6 AWG (75A) and 4 AWG (95A) also fail after correction
(65.25A and 82.65A respectively), but 3 AWG is the smallest that meets the requirement.
Why Wrong:
A - 6 AWG has a corrected ampacity of 65.25A, which is insufficient for the required
64.66A after rounding, but the question requires the minimum size that meets the
load, and 6 AWG is too small.
B - 4 AWG has a corrected ampacity of 82.65A, which is sufficient, but it is not the
minimum size.
D - 2 AWG is larger than necessary; 3 AWG is the minimum that satisfies the load and
correction factors.
Reference: NEC 2026, Article 210.20(A), Table 310.16, Table 310.15(B)(2)(a)
Q2. In a multi-story commercial building, a 120/208V, 3-phase, 4-wire feeder supplies
a panelboard. The feeder is protected by a 400A circuit breaker. The calculated load
is 320A. The feeder conductors are 500 kcmil copper with THHN insulation, run in a
conduit with two other current-carrying conductors. The ambient temperature is
40°C. What is the minimum size of the equipment grounding conductor (EGC)
required for this feeder, based on the overcurrent device rating?
A. 1/0 AWG
B. 2/0 AWG
C. 3/0 AWG
D. 4/0 AWG
Correct Answer: B. 2/0 AWG
Rationale: Per NEC Table 250.122, the EGC size is based on the rating of the overcurrent
device protecting the circuit. For a 400A breaker, the minimum EGC size is 2/0 AWG
