NEIEP Mechanics Exam Questions and
Answers (2026) | Comprehensive Review
with Detailed Rationales | A+ Verified
• A MOV (Metal Oxide Varistor) burns out. You replace it, but cannot read voltage
or resistance. What should you do? -✓✓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? -✓✓Suicide Circuit - 425
• You have an old DC motor and are adding an SCR drive, what do you do to the
interpoles? -✓✓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?
-✓✓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? -✓✓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? -✓✓Door Operator
disconnect -535
,• The contractor requests that the vertical center of a Rack and Pinion hoist be
moved. How do you do this? -✓✓Adjust tie downs and wall ties - 850
• Working pressure on a Hydro is 400 PSI. What is the maximum relief valve
setting? -✓✓400 x 150%= 600 PSI - 815
• What must be installed on a false care before operation? -✓✓Spring Loaded
safeties - 110
• There is slight arcing between the brush and commutator. What action must be
taken? -✓✓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? -✓✓18,000lbs -210
• How much resistance is measured over a normally closed switch? -✓✓.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? -✓✓traveling cable has a cut/exposed wire or a short - 515
• How is a class 1 yearly buffer test preformed? -✓✓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? -✓✓4
1 every 100ft - 505-510
• How is stainless steel drilled out? -✓✓Slow speed and constant pressure - 205
• What is the required amout of retainer clips for wedge shackles and what is the
spacing? -✓✓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? -✓✓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? -
✓✓Finish side facing the cutting edge of the tool. Blade will burr the backside. -
225
• How do you cut a finished floor? -✓✓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? -✓✓320 VAC
3 phase full wave= 1.33 x output voltage. - 715
• A car is loaded with 125% and sinks, why? -✓✓Slipping through the brake
