NEIEP Mechanics Exam Questions and Verified Answers Graded A+ 2026/27
A contractor wants to raise the car speed from 100 fpm to 125 fpm, it currently has a 12" sheave.
What is required? - 100 fpm/125 fpm= 12"/ X =15
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
