Mechanics Exam NEIEP 2025/2026 –
Verified Questions with Correct
Answers (100% Guaranteed Pass)
1. Elevator Electrical Systems
1. An MOV burns out, and you replace it but cannot read voltage or resistance. What should
you do?
A. Test the circuit with a multimeter
B. Replace it with a larger one
C. Bypass the MOV
D. Reinstall the original MOV
Answer: B. Replace it with a larger one
Rationale: A metal oxide varistor (MOV) protects circuits by absorbing voltage
spikes. If it burns out and voltage/resistance cannot be read, replacing it with a
larger one (e.g., rated for higher voltage) ensures continued protection without
risking further damage. Bypassing (C) or reinstalling (D) is unsafe, and testing (A)
doesn’t address the issue.
2. In a Ward-Leonard circuit, the brake is set, but the motor tries to slip through the brake.
What circuit is the issue?
A. Control circuit
B. Suicide circuit
C. Brake circuit
D. Generator circuit
Answer: B. Suicide circuit
Rationale: The suicide circuit in a Ward-Leonard system controls the motor’s
field excitation. If faulty, it can cause the motor to attempt to run despite the brake
being set, leading to slipping. Other circuits (A, C, D) are not directly responsible
for this issue.
3. How much resistance is typically measured across a normally closed switch?
A. Infinite ohms
B. 50–100 ohms
C. 1–2 ohms
D. 10–20 ohms
Answer: C. 1–2 ohms
Rationale: A normally closed switch should have minimal resistance (1–2 ohms)
when closed, allowing current to flow freely. Infinite resistance (A) indicates an open
circuit, and higher resistances (B, D) suggest a faulty switch or poor connection.
4. A car traveling in the hoistway stops at the same point and blows a fuse. What is the
likely problem?

, 2


A. Faulty controller
B. Short in the traveling cable
C. Overloaded motor
D. Misaligned governor
Answer: B. Short in the traveling cable
Rationale: A short in the traveling cable can cause the car to stop at a specific
point due to a fault in the wiring at that position, blowing the fuse. Other issues (A,
C, D) are less likely to cause consistent stopping at the same point.
5. What is the maximum length for motor-generator leads outside a controller per NEC?
A. 3 feet
B. 6 feet
C. 9 feet
D. 12 feet
Answer: B. 6 feet
Rationale: Per NEC Article 620, motor-generator leads outside a controller
must not exceed 6 feet to minimize electrical hazards and ensure proper operation.




2. Hydraulic Elevators
6. A hydraulic elevator runs up with no load but not with a full load. What is the issue?
A. Faulty motor windings
B. Relief valve set too low
C. Clogged oil filter
D. Misaligned pump
Answer: B. Relief valve set too low
Rationale: If the relief valve is set too low, the hydraulic system cannot generate
enough pressure to lift a full load, but it may function with no load. Other issues (A,
C, D) would likely affect operation under all conditions.
7. What is the correct relief valve setting for a hydraulic elevator with a working pressure of
400 PSI?
A. 400 PSI
B. 500 PSI
C. 600 PSI
D. 800 PSI
Answer: C. 600 PSI
Rationale: ASME A17.1 specifies the relief valve setting for hydraulic elevators
should be 150% of the working pressure. For 400 PSI, 400 × 1.5 = 600 PSI.
8. You perform a static load cylinder leak test with the pit valve closed, and the car sinks 6
inches in 15 minutes. What is the cause?
A. Faulty check valve
B. Worn piston seals
C. Low oil level
D. Misaligned jack

, 3


Answer: B. Worn piston seals
Rationale: Worn piston seals allow oil to leak past the piston, causing the car to
sink during a static load test. A faulty check valve (A) would affect dynamic
operation, low oil (C) would cause other issues, and misalignment (D) is unrelated to
leakage.
9. Why must a hydraulic elevator car be placed on jack posts before servicing the packing
head?
A. To prevent electrical shock
B. To stabilize the car
C. Because it is supported by a column of oil
D. To align the counterweight
Answer: C. Because it is supported by a column of oil
Rationale: Hydraulic elevators rely on a column of oil for support. Jack posts
are used to secure the car during packing head service to prevent it from sinking
when oil pressure is released.
10. What must be done before checking pump drive belts on a hydraulic elevator?
A. Open the pit valve
B. Pull the main disconnect switch
C. Engage the governor
D. Lower the car to the pit
Answer: B. Pull the main disconnect switch
Rationale: Pulling the main disconnect switch ensures the system is de-
energized, preventing accidental movement or injury while checking the belts.
Other actions (A, C, D) do not ensure safety.




3. Safety and ASME/OSHA Regulations
11. What is required by ASME A17.1 on an elevator car top?
A. Emergency exit only
B. Inspection station, light, and duplex outlet
C. Fire extinguisher
D. Handrail and ladder
Answer: B. Inspection station, light, and duplex outlet
Rationale: ASME A17.1 requires an inspection station, light, and duplex outlet
on the car top to ensure safe maintenance and inspection. Other options (A, C, D)
are not mandatory.
12. You enter a pit with toxic fumes. How should you proceed?
A. Proceed with a standard mask
B. Follow OSHA confined space entry procedures
C. Ventilate the pit with a fan only
D. Ignore the fumes if mild
Answer: B. Follow OSHA confined space entry procedures
