QUESTIONS 1–150
Question 1
A proposed NYC electrical project includes a new service installation totaling 1,200 kVA.
Which statement best describes the DOB electrical plan-review requirement?
A. Plan review is unnecessary because the installation is below 2,000 kVA.
B. Electrical Plan Review is required because the service equipment totals at least 1,000 kVA.
,C. Plan review is required only if the service voltage exceeds 600 volts.
D. Plan review is required only after electrical installation begins.
Correct Answer: B
Explanation: Under the current NYC Electrical Code framework, DOB Electrical Plan
Review applies to electrical installations totaling 1,000 kVA or greater.
Question 2
A project proposes a new 480-volt electrical service rated at 900 kVA. Which additional
condition would independently trigger NYC Electrical Plan Review?
A. The installation contains more than 20 branch circuits.
B. The project includes LED lighting.
C. The installation is revised to operate above 600 volts.
D. The building contains more than five stories.
Correct Answer: C
Explanation: New or revised electrical installations above 600 volts require Electrical Plan
Review regardless of the kVA rating.
Question 3
A designer submits plans for a 1,200-kVA service but fails to distinguish existing equipment
from proposed equipment. What is the most appropriate plan-review conclusion?
A. Accept the drawings because the one-line diagram is sufficient.
B. Accept the drawings if the equipment schedule is complete.
C. Reject or object because the drawings do not clearly identify existing and new
installations.
D. Accept the drawings if the contractor provides photographs later.
Correct Answer: C
Explanation: Electrical submissions must clearly identify existing installations and
proposed work so the examiner can determine the actual scope and code implications.
Question 4
An electrical plan depicts a service entrance but the building is set back substantially from
the property line. Which information is particularly important on the plan?
A. Only the building's gross floor area.
B. Underground service conductors, including wire and raceway sizes.
,C. The contractor's estimated labor hours.
D. Only the utility meter serial number.
Correct Answer: B
Explanation: Where the building is set back from the property line, the plan should show
the underground service conductors, including conductor and raceway sizes.
Question 5
A plan examiner receives a drawing package containing illegible electrical symbols,
inconsistent abbreviations, and nonstandard notation. Which deficiency is most directly
implicated?
A. Failure to provide a load calculation.
B. Failure to use clear, legible drawings and standard notations.
C. Failure to provide a zoning analysis.
D. Failure to identify the contractor's license number.
Correct Answer: B
Explanation: Electrical plan submissions must be clear, legible, and use standard notations
to support meaningful technical review.
Question 6
A project includes multiple electrical service locations within one building. Which plan-
review issue becomes especially important?
A. The electrical plans must identify the location of the other switchboard rooms.
B. Every switchboard must be painted the same color.
C. All service equipment must be located outdoors.
D. Every switchboard must have an independent utility account.
Correct Answer: A
Explanation: Where multiple service locations exist, appropriate signage and drawing
information must identify the locations of the other switchboard rooms.
Question 7
A designer submits a 1,500-kVA installation with a one-line diagram but omits the
equipment-room layout even though equipment clearances are affected. What is the
strongest objection?
A. A one-line diagram is never permitted.
B. An equipment-room layout may be required to demonstrate equipment arrangement
, and clearances.
C. Equipment rooms do not need to appear on electrical plans.
D. Only architectural drawings can show electrical equipment.
Correct Answer: B
Explanation: Electrical submissions must adequately demonstrate equipment arrangement
and required working clearances when applicable.
Question 8
A proposed electrical plan shows the service equipment but does not indicate the route
from the service entrance to the equipment. Why is this significant?
A. The route is irrelevant after utility approval.
B. The examiner must be able to evaluate the service arrangement and how service
conductors reach the equipment.
C. Only the electrical contractor determines the service route.
D. Service conductors are never required on plan drawings.
Correct Answer: B
Explanation: The service arrangement and means by which service is extended to the
equipment are important components of electrical plan review.
Question 9
A 1,100-kVA electrical installation includes a switchboard room whose door opens toward
an inaccessible mechanical space. Which plan-review issue should receive priority?
A. Wall paint classification.
B. Means of egress from the switchboard room.
C. Fixture color temperature.
D. Utility billing configuration.
Correct Answer: B
Explanation: Electrical plans should show the means of egress from switchboard rooms
and where those exits lead.
Question 10
A design professional submits incomplete electrical drawings and expects the plan examiner
to identify every missing detail through technical objections. Which response is most
appropriate?
