Section One: Questions 1–100
Question 1
,What is the maximum number of overcurrent devices permitted in a single lighting and
appliance branch-circuit panelboard according to traditional NEC rules before recent updates
removed the physical limit, though still relevant for legacy NYC installations?
A. 30
B. 42
C. 48
D. 60
🟢 B. 42
🔴 Explanation: Historically, legacy codes capped lighting and appliance branch-circuit
panelboards at a maximum of 42 overcurrent devices (excluding the main breaker) in a
single cabinet to prevent excessive heat buildup and concentration of circuits.
Question 2
A 240-volt, single-phase, 10 kW commercial dishwasher requires a dedicated branch circuit.
What is the minimum ampacity required for the conductors supplying this continuous load?
A. 41.7 amperes
B. 52.1 amperes
,C. 62.5 amperes
D. 75.0 amperes
🟢 B. 52.1 amperes
🔴 Explanation: First, determine the current by dividing power by voltage: 10,000W / 240V =
41.67A. Because commercial appliances running continuously must be rated at 125% of the
continuous load, multiply 41.67A by 1.25 to get 52.08A, which rounds up to 52.1 amperes.
Question 3
Under the NYC Electrical Code amendments, which of the following wiring methods is
generally prohibited for use in commercial high-rise occupancies?
A. Rigid Metal Conduit (RMC)
B. Electrical Metallic Tubing (EMT)
C. Nonmetallic-Sheathed Cable (Type NM)
D. Metal-Clad Cable (Type MC)
🟢 C. Nonmetallic-Sheathed Cable (Type NM)
🔴 Explanation: New York City amendments place strict limitations on nonmetallic wiring
methods due to high population density and structural considerations. Type NM (Romex) is
, largely restricted to specific residential structures under three stories, making it prohibited in
commercial high-rise buildings.
Question 4
When installing a grounding electrode system where a metal underground water pipe is used
as an electrode, how many feet of the pipe must be in direct contact with the earth to qualify
as an electrode?
A. 5 feet
B. 8 feet
C. 10 feet
D. 15 feet
🟢 C. 10 feet
🔴 Explanation: The code requires that a metal underground water pipe electrode must
include at least 10 feet (3.0 meters) of direct earth contact to ensure a low-resistance path to
ground before being utilized as part of the grounding electrode system.
Question 5
An electrician discovers that a co-worker is bypass-testing a faulty tamper-resistant
receptacle in a pediatric clinic playroom by modifying the internal shutters instead of
