QUESTIONS AND CORRECT ANSWERS) |
ALREADY GRADED A+ | 100% VERIFIED
Introduction
This structured NEIEP 800 Final Exam format for 2026–2027 provides the complete layout
for generating high-quality exam-style questions with correct answers and rationales. It
emphasizes technical safety protocols, system mechanics, code compliance, and operational
safety critical to professional practice and successful certification.
The total weight of an elevator is 8,100 lbs. If the plunger area is 50 square inches,
what is the system pressure?
A. 150 psi
B. 162 psi
C. 175 psi
D. 180 psi
Rationale: Pressure = Force / Area. 8, = 162 psi.
Which component is designed to stop the escalator if an object becomes wedged
between the step and the skirt panel?
A. Comb impact switch
B. Skirt obstruction switch
C. Emergency stop button
D. Step level switch
Rationale: Skirt switches are safety devices that detect deflections or objects between the
step and the skirt.
What is the primary purpose of a Wye-Delta starter in an elevator motor circuit?
A. To increase torque at high speeds
,B. To reduce the starting current
C. To eliminate the need for a brake
D. To reverse the direction of the motor
Rationale: Wye-Delta starting reduces the inrush current during the initial motor startup
phase.
When using wire rope, the diameter of the sheaves must be at least how many times
the diameter of the suspension ropes?
A. 20 times
B. 30 times
C. 40 times
D. 50 times
Rationale: Standard elevator engineering practice and code often require a 30:1 ratio to
prevent excessive rope wear.
Which type of corrosion is caused by stray electrical currents moving through the
hydraulic cylinder?
A. Galvanic corrosion
B. Electrolysis
C. Oxidation
D. Pitting
Rationale: Electrolysis occurs when electrical current enters the ground through the
hydraulic system, causing rapid metal loss.
The area of a circular plunger is calculated using which formula?
A. Diameter x 2
B. Pi x Radius squared
C. Length x Width
, D. Circumference / Pi
Rationale: Area = πr² is the standard formula for circular surfaces like plungers.
What is the maximum allowable incline for a standard escalator?
A. 20 degrees
B. 30 degrees
C. 35 degrees
D. 45 degrees
Rationale: ASME A17.1 code specifies that the angle of inclination shall not exceed 30
degrees.
Which device prevents the elevator from moving if the door is open?
A. Limit switch
B. Interlock
C. Governor
D. Leveling sensor
Rationale: Interlocks ensure electrical and mechanical closure of the doors before the car
can move.
In a hydraulic system, a 'silencer' is used to reduce:
A. Heat
B. Vibration and noise
C. Pressure
D. Speed
Rationale: Silencers are installed in the discharge line to dampen hydraulic pulsations.
What type of safety is used on an elevator that utilizes an oil buffer?
