During review of an electrical permit application for a new commercial
building, the plans show a 400A, 120/208V, 3-phase, 4-wire service.
The load calculation indicates a calculated service load of 365A. Which
is the most appropriate initial conclusion by the permit reviewer?
A. Reject the application because the service rating must exceed 400A
B. Approve the application because 365A is less than 400A, regardless
of all other factors
C. Continue the review to verify that the load calculation methodology,
service equipment rating, conductors, overcurrent protection, and
applicable demand factors are compliant
D. Require the applicant to install a 600A service because commercial
buildings cannot use 400A services
Answer: C.
Rationale: A service rating exceeding the calculated load is necessary
but not, by itself, sufficient for permit approval. The reviewer must
verify that the load calculation is properly prepared, that demand
factors are correctly applied, and that the service conductors, service
disconnect, overcurrent protection, equipment ratings, grounding and
bonding, and other applicable requirements are consistent with the
proposed installation.

A permit application proposes a 120/240V single-phase dwelling
service. The calculated load is 142A, and the applicant proposes a 150A
service. Which review issue is most important before accepting the
proposed service rating?
A. Whether the service disconnect is painted gray
B. Whether the load calculation correctly accounts for all required loads
and permitted demand factors
C. Whether the service mast is exactly 6 feet tall
D. Whether the dwelling has more than one bathroom
Answer: B.
Rationale: The calculated load is the foundation for determining
service capacity. A reviewer should verify that general lighting, small-
appliance loads, laundry loads, appliances, HVAC equipment, electric
vehicle charging, heating, cooking equipment, and other applicable
loads have been properly considered. Correct demand factors must be
applied rather than simply reducing the total connected load
arbitrarily.
3.
An electrical permit application contains architectural plans and an
electrical floor plan. The electrical plan identifies receptacle locations
but does not show panel schedules, circuit numbers, conductor sizes,
overcurrent protection, or panelboard ratings. What should the reviewer
generally do?
A. Approve the permit because receptacle locations are sufficient
B. Approve the permit and allow the electrician to determine circuit
details in the field
2
,C. Request sufficient electrical documentation to demonstrate
compliance with applicable requirements
D. Reject the project permanently
Answer: C.
Rationale: Permit plans must provide enough information for the
authority having jurisdiction to determine whether the proposed work
complies with applicable electrical requirements. Panel schedules,
circuit identification, conductor and overcurrent-protection
information, equipment ratings, and other relevant details may be
necessary depending on the project scope and adopted requirements.
4.
A proposed branch circuit consists of 12 AWG copper conductors
protected by a 30A circuit breaker. No special conductor ampacity
provision is identified on the plans. What is the primary concern?
A. The conductor may be undersized for the overcurrent protection
B. The breaker is automatically required to be 15A
C. Copper conductors cannot be used for branch circuits
D. A 30A breaker always requires 8 AWG copper
Answer: A.
Rationale: In ordinary applications, 12 AWG copper conductors are
commonly associated with 20A overcurrent protection, subject to the
applicable code rules and specific conditions. A reviewer should
determine whether the proposed 30A protection is permitted under the
applicable conductor ampacity provisions, including any applicable
limitations or special rules.

, A permit reviewer notices that a panel schedule lists a 20A branch
circuit serving several receptacles, but the drawings indicate that the
circuit also supplies a fixed electric heater. What should the reviewer
investigate first?
A. Whether the circuit's calculated load is within its permitted capacity
and whether the heater requires dedicated or appropriately sized circuitry
B. Whether receptacles are required to be blue
C. Whether all receptacles must be connected to a 40A breaker
D. Whether the heater can be ignored because it is permanently installed
Answer: A.
Rationale: Fixed electric heating equipment can represent a
substantial continuous or calculated load. The reviewer must verify
circuit ampacity, overcurrent protection, load calculation, equipment-
specific requirements, and whether the equipment requires an
individual branch circuit or other special treatment.
6.
A commercial tenant improvement includes a new panelboard. The
panel schedule identifies multiple circuits, but the plans do not indicate
the panel's main overcurrent protection or bus rating. Why is this a
significant review concern?
A. Panelboards do not require ratings
B. The reviewer cannot adequately verify that the panelboard and
overcurrent protection are appropriately rated for the proposed
installation
C. Panel schedules are only decorative documents
D. Only the electrician needs to know the panel rating
Answer: B.
