1. A C-7 contractor is installing a hydraulic elevator. The piston must be anchored to the
foundation using a bottom plate. What is the primary reason for ensuring the bottom
plate is perfectly level within 0.001 inch per foot?
A) To reduce oil foam and seal wear
B) To simplify electrical wiring
C) To allow faster installation of guide rails
D) To meet fire code clearance
Answer: A
Explanation: In hydraulic elevators, the piston bottom plate must be level to ensure the
piston is perfectly vertical. Any tilt causes uneven wear on the cylinder wall and packing
seals, leading to oil leaks, foaming, and premature seal failure.
2. According to ASME A17.1, the safety factor for wire rope suspension means for a
traction elevator with 4 ropes is:
A) 5:1
B) 7.5:1
C) 10:1
D) 12:1
Answer: B
Explanation: ASME A17.1 requires a minimum safety factor of 7.5 for traction elevator
ropes when 4 or more ropes are used. For 3 ropes, it is 8:1; for 2 ropes, 9:1. This ensures
redundancy and safe load capacity.
,3. In a machine-room-less (MRL) elevator installed in Nevada, the controller must be
located:
A) In a separate locked room adjacent to the hoistway
B) Inside the hoistway within a locked enclosure
C) At the top of the hoistway with no access restriction
D) At the bottom landing inside a closet
Answer: B
Explanation: MRL elevators have the controller and machinery inside the hoistway,
typically within a locked enclosure at the top or side. Nevada adopts ASME A17.1-2019,
which permits this provided safe access and disconnecting means are present.
4. A C-7 contractor is installing a pit ladder in a 6-foot deep pit. What is the minimum
clear distance from the pit floor to the lowest rung required by IBC 2018?
A) 6 inches
B) 12 inches
C) 18 inches
D) 24 inches
Answer: B
Explanation: IBC 2018 (Section 3005.1) requires that pit ladders have the lowest rung no
more than 12 inches above the pit floor to allow safe stepping onto the ladder. For pits
deeper than 5 feet, a permanent ladder is mandatory in Nevada.
5. When adjusting door closing force on a power-operated sliding elevator door, what is
the maximum kinetic energy allowed at the leading edge per ASME A17.1?
A) 7 ft-lb
B) 5 ft-lb
C) 3.5 ft-lb
D) 1.5 ft-lb
Answer: C
Explanation: ASME A17.1 limits kinetic energy at the leading edge of a power-operated
,sliding door to 3.5 ft-lb to prevent injury. For swing doors, it is 7 ft-lb. The force must be
measured with a force gauge.
6. In Nevada, what is the minimum required illumination (in foot-candles) at the car
floor level when the elevator car is at any landing?
A) 1 foot-candle
B) 2 foot-candles
C) 5 foot-candles
D) 10 foot-candles
Answer: C
Explanation: Nevada Administrative Code (NAC) 477.275 adopts ICC A117.1, which
requires minimum 5 foot-candles inside the elevator car measured at the floor level for
accessibility and safety.
7. A C-7 contractor is installing an inclined wheelchair platform lift. What is the
maximum travel distance allowed under ASME A18.1 before a fire-rated enclosure is
required?
A) 12 feet
B) 20 feet
C) 30 feet
D) 60 feet
Answer: C
Explanation: ASME A18.1-2017 allows inclined platform lifts to travel up to 30 feet
without a fire-rated hoistway enclosure. Beyond that, building codes require enclosure
with 1-hour fire rating.
8. What is the required inside diameter of a steel conduit for elevator traveling cables
according to NEC Article 620?
A) At least 2 inches
B) At least 1 inch
C) At least the cable diameter plus 25%
D) At least 50% larger than cable diameter
, Answer: D
Explanation: NEC 620.21(A)(2) requires that traveling cable conduits have an inside
diameter at least 50% larger than the cable’s diameter to prevent abrasion and allow
free movement.
9. During a full-load overspeed test on a hydraulic elevator, the relief valve must open at
what percentage above the maximum system pressure?
A) 10%
B) 15%
C) 20%
D) 25%
Answer: C
Explanation: Per ASME A17.1, the pressure relief valve on hydraulic elevators shall be set
to open at not more than 20% above the maximum operating pressure but not less than
120% of the maximum static pressure.
10. In Nevada, who is authorized to perform the annual pressure test on hydraulic
elevator cylinders?
A) Any C-7 contractor
B) A certified elevator inspector only
C) A C-7 contractor with a hydronics endorsement
D) A professional engineer or licensed contractor with proof of training
Answer: D
Explanation: Nevada requires that hydraulic cylinder pressure tests be performed by a
licensed professional engineer or a C-7 contractor who can demonstrate training in
hydraulic testing procedures per NAC 477.245.
11. When installing a pit stop switch, it must be located:
A) Within 12 inches of the pit access door
B) At the bottom of the pit ladder
C) Between 18 and 42 inches above the pit floor
D) On the hoistway wall opposite the ladder
