*Section One*
1. What is the maximum number of overcurrent devices allowed in a single lighting and
appliance branch-circuit panelboard?
,A. 30
B. 42
C. 48
D. There is no longer a specific limit in the NEC
🟢 D. There is no longer a specific limit in the NEC
🔴 Explanation: Previous editions of the NEC limited lighting and appliance panelboards
to 42 overcurrent devices, but this limit was removed in recent code cycles; the capacity is
now determined by the panelboard's listing and physical space.
2. A 240-volt single-phase motor draws 20 amperes. What is the power consumption in
kilowatts?
A. 4.0 kW
B. 4.8 kW
C. 5.2 kW
D. 9.6 kW
🟢 B. 4.8 kW
🔴 Explanation: Power is calculated by multiplying voltage by current (P = V × I ).
240V × 20A = 4, 800 Watts, which is 4.8 kW.
, 3. Which of the following is the required minimum clearance for overhead service
conductors from a window that is designed to be opened?
A. 1 foot
B. 3 feet
C. 6 feet
D. 10 feet
🟢 B. 3 feet
🔴 Explanation: NEC 230.9(A) requires that service conductors have a clearance of not less
than 3 feet from windows that are designed to be opened, doors, porches, stairs, or similar
locations.
4. When installing a ground rod, what is the minimum depth it must be driven into the
earth?
A. 6 feet
B. 8 feet
C. 10 feet
D. 12 feet
🟢 B. 8 feet
, 🔴 Explanation: According to NEC 250.53(G), rod and pipe electrodes shall be installed
such that at least 8 feet of length is in contact with the soil.
5. What is the color-coding for a high-leg conductor in a 4-wire, delta-connected
system?
A. Red
B. Black
C. Orange
D. Blue
🟢 C. Orange
🔴 Explanation: NEC 110.15 requires the high-leg conductor (the phase with the higher
voltage to ground) to be identified by an outer finish that is orange in color.
6. A branch circuit for a guest room in a hotel must be protected by an AFCI if it
contains which of the following?
A. Outlets for lighting
B. Receptacles only
C. Both A and B
D. AFCI is not required in hotels
