NEIEP MECHANICS EXAM SCRIPT 2026
QUESTIONS WITH ANSWERS GRADED A+
●● 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
●● On a Ward-Leonard circuit the brake is set, but the motor is trying to
slip through the brake. What is the issue? Answer: Suicide Circuit - 425
●● 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
●● 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
●● 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
●● 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 -535
,●● 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
●● Working pressure on a Hydro is 400 PSI. What is the maximum
relief valve setting? Answer: 400 x 150%= 600 PSI - 815
●● What must be installed on a false care before operation? Answer:
Spring Loaded safeties - 110
●● There is slight arcing between the brush and commutator. What
action must be taken? Answer: None
Note: Heavy arcing= light brush pressure, Heavy brush pressure=
mechanical wear
●● If rigging is roped 3:1 and a BEAM CLAMP is used to lift a 6,000lb
load. What is the beam capacity? Answer: 18,000lbs -210
●● How much resistance is measured over a normally closed switch?
Answer: .2 Ohms- should be zero but will never be that low
●● 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
,●● How is a class 1 yearly buffer test preformed? Answer: Car at the
bottom landing and on inspection, jump out direction and final limits.
With pit clear, run down to compress the buffers, buffers should fully
extend within 90 seconds.
Note: 5 yr is Full load, full speed - 555
●● How many strain supports are required on a 350 ft raceway? Answer:
4
1 every 100ft - 505-510
●● How is stainless steel drilled out? Answer: Slow speed and constant
pressure - 205
●● What is the required amout of retainer clips for wedge shackles and
what is the spacing? Answer: At least 2. First clip being 4 times the
diameter of the rope from the top of the shackle, and the second clip is 8
times the diameter of the rope away from the shackle. - 245
●● A 300 ohm resistor burns out, but you dont have another one. How
can you make one? Answer: 2- 600 ohms resistors in parallel is 300
ohms. Resistance is half of the highest resistor in the parallel circuit. 3-
225 ohms is 75 ohms. - 345
, ●● 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. - 225
●● How do you cut a finished floor? Answer: Cutting blade away from
the finished side - 255
●● A 480 VAC stepdown 240 VAC transformer is connected to a 3 phase
rectifier, what is the output voltage? Answer: 320 VAC
3 phase full wave= 1.33 x output voltage. - 715
●● A car is loaded with 125% and sinks, why? Answer: Slipping through
the brake
●● IF you find a broken or missing barricade what should you do?
Answer: Write up a formal inspection request
●● What are the consequences of misaligned joints on a rack and
pinion? Answer: Broken gear teeth. CWT derailment. Excessive
wear/crease the surface of the tube. - 850
●● A dumbwaiter is 9 sqft in area, 4 ft in height, and capacity is
13.9lb/ft. What is the total capacity? Answer: 9 X 4 x 13.9= 500lbs Max
Capacity
