NEIEP MECHANICS COMPREHENSIVE TEST
2026 QUESTIONS WITH SOLUTIONS
GRADED A+
●● 2. A MOV (Metal Oxide Varistor) burns out. You replace it, but
cannot read voltage or resistance. What should you do?. Answer:
Replace it with a larger MOV 630
●● 3. On a Ward-Leonard circuit the break is set, but the motor is trying
to slip through the break. What is the issue?. Answer: Suicide Circuit
425
●● 4. You have an old DC motor and are adding an SCR drive, what do
you do to the interpoles?. Answer: Leave the interpoles alone. When
adding a SCR drive to the generator, the series loop is removed, as are
the 3 resistors. Everything else remains the same.
●● 5. A hydro runs up with no load, but will not run with a full load.
What is the issue?. Answer: The relief valve is set too low 815
●● 6. Runby for a 1:1 hits the CWT buffer 4" below the top landing.
CWT runby should be set at 18". How much should the ropes be
shortened?. Answer: 22" 235
,●● 7. You need to work on a freight door retiring cam, you LOTO the
main line but there is still power on the cam. What circuit is still hot?.
Answer: Door Operator Disconnect/ Main Line Disconnect 535
●● 8. The contractor requests that the vertical center of a Rack and
Pinion hoist be moved. How do you do this?. Answer: Adjust Tie Downs
and Wall Ties 850
●● 9. Working pressure on a Hydro is 400psi. What is the maximum
relief valve setting?. Answer: 400psi x 150%= 600psi 815
●● 10. What must be installed on a false car before operation?. Answer:
Spring Loaded Safeties 110
●● 11. There is slight arcing between the brush and commutator. What
action must be taken?. Answer: None
Note: Heavy arcing=Light brush pressure, Heavy bush
pressure=mechanical wear 430
●● 12. If rigging gear is roped 3:1 and a BEAM CLAMP is used to lift a
6,000lb load. What is the beam capacity requirement?. Answer:
18,000lbs.
Note: Beam capacity is cut in half with use of clamp, when rigging all
blocks, rope, and clamps will be Equal to the lowest load rating 210
,●● 13. How much resistance is measured over a normally closed
switch?. Answer: 1.2ohms. should be zero, but will never be that low
●● 14. A car traveling in the hoistway always stops at the same spot and
blows a fuse. What causes this. Answer: Traveling cable has a
cut/exposed wire or a short 515
●● 15. How is a class 1 yearly buffer test preformed?. Answer: Car at
bottom landing and on inspection, jump out direction and final limits.
With pit clear, run down to compress buffers, buffers should fully extend
within 90 seconds.
Note: 5yr: Full load Full speed CWT: Full speed Empty 555 (may be 60
on test)
●● 16. How many strain supports are required on a 350ft raceway?.
Answer: 4. 1 every 100ft 505-510
●● 17) How is stainless steel drilled out?. Answer: Slow speed and
constant pressure 205
●● 18. What is the required amount of retainer clips for wedge shackles
and what is the spacing?. Answer: At least 2. First clip being maximum 4
times the diameter of the rope from the top of the shackle, and the
second clip is maximum 8 times the diameter of the rope above the first
clip. 245
, ●● 19. A 300ohm resistor burns out, but you don't have another one.
How can you make one?. Answer: 2-600ohm resistors in parallel is
300ohms. Resistance is half of highest resistor in parallel circuit. 3-
225ohm resistors in parallel is 75ohms. 345
●● 20. When cutting laminated panels, which direction should the finish
side face?. Answer: Finish side facing the cutting edge of the tool. Blade
will burr the backside 255
●● 21. How do you cut a finished floor?. Answer: Cutting blade away
from finished side 255
●● 22. A 480vac stepdown 240vac transformer is connected to a 3 phase
rectifier, what is the output voltage?. Answer: 320vac 3 phase full wave
= 1.33x output voltage. 715
●● 23) Car is loaded with 125% and sinks. Why?. Answer: Slipping
through the break
●● 24. If you find a broken or missing barricade what should you do?.
Answer: Write up a formal inspection request
