Oregon Elevator Electrical and Elevator Mechanical EM Exam

Oregon Elevator Electrical and Elevator Mechanical EM Exam
**Question 1.** Which Oregon Administrative Rule (OAR) specifically requires a
licensed elevator contractor to obtain a permit before performing any alteration
to an existing elevator?

A) OAR 839‑020‑0010

B) OAR 839‑020‑0035

C) OAR 839‑020‑0060

D) OAR 839‑020‑0090

**Answer:** B

**Explanation:** OAR 839‑020‑0035 outlines the permit‑application process for
alterations, mandating that only a licensed contractor may submit the permit.



**Question 2.** Under ASME A17.1, what is the minimum required fire‑rating for
a hoistway enclosure in a building classified as “high‑rise”?

A) 1‑hour fire‑resistance rating

B) 2‑hour fire‑resistance rating

C) 3‑hour fire‑resistance rating

D) No fire‑rating required

**Answer:** B

**Explanation:** High‑rise hoistways must have a minimum 2‑hour fire‑resistance
rating to contain fire spread between floors.



**Question 3.** When performing Lockout/Tagout (LOTO) on an elevator
controller, which of the following must be documented before work begins?

, Oregon Elevator Electrical and Elevator Mechanical EM Exam
A) The name of the electrician only

B) The estimated time to complete the work only

C) The specific energy sources being isolated and the method of isolation

D) The brand of the controller

**Answer:** C

**Explanation:** Proper LOTO requires identification of all energy sources and the
isolation method to ensure safety.



**Question 4.** In a traction elevator, the guide rail size is primarily determined
by which factor?

A) The height of the hoistway

B) The car’s rated load and speed

C) The type of machine room ventilation

D) The number of doors on the car

**Answer:** B

**Explanation:** Rail dimensions must support the dynamic loads generated by
the car’s weight and speed.



**Question 5.** According to ASME A17.1, what is the purpose of a “runby” in a
traction elevator system?

A) To provide a decorative element for the car interior

B) To allow the car to move past the landing without stopping in case of a safety
trip

, Oregon Elevator Electrical and Elevator Mechanical EM Exam
C) To reduce noise in the machine room

D) To increase the elevator’s travel speed

**Answer:** B

**Explanation:** A runby permits the car to clear the landing zone after a safety
trip, preventing obstruction.



**Question 6.** Which type of buffer is required for a traction elevator traveling
at speeds greater than 200 fpm?

A) Spring buffer only

B) Oil buffer only

C) Combination oil‑and‑spring buffer

D) No buffer required

**Answer:** C

**Explanation:** High‑speed elevators need a combination buffer to absorb
kinetic energy safely.



**Question 7.** When selecting traction ropes, the minimum breaking strength
must be at least how many times the rated load of the car?

A) 1.5 times

B) 2.0 times

C) 3.0 times

D) 4.0 times

**Answer:** C

, Oregon Elevator Electrical and Elevator Mechanical EM Exam
**Explanation:** ASME A17.1 requires a minimum breaking strength of three
times the rated load for safety margin.



**Question 8.** A gearless traction machine is installed in a machine room with a
concrete slab floor. What is the required method of securing the machine to the
floor?

A) Bolting directly to the slab with anchor bolts rated for seismic loads

B) Using a steel frame that rests on the slab without bolts

C) Placing the machine on a rubber pad only

D) No securing required for gearless machines

**Answer:** A

**Explanation:** Gearless machines must be anchored to resist vibration and
seismic forces.



**Question 9.** In NEC Article 620, what is the maximum allowable voltage drop
for feeder conductors supplying an elevator motor, assuming a 3‑phase, 460 V
system?

A) 1 %

B) 2 %

C) 3 %

D) 5 %

**Answer:** B

**Explanation:** NEC 620‑13 limits voltage drop to 2 % for feeder conductors to
maintain motor performance.
