EIAT Tool Recognition and Use 3 — Questions and Answers
Question 1: Which tool is used to bend rigid electrical conduit to a precise angle during elevator wiring?
- Conduit bender (Correct answer)
- Pipe wrench
- Hacksaw
- Hammer and mandrel
Correct answer: Conduit bender
A conduit bender allows electricians to form accurate bends in rigid conduit without kinking the pipe.
Question 2: An elevator technician must identify whether a shaft wall penetration is plumb. Which tool is used?
- Plumb bob (Correct answer)
- Level ruler
- Try square
- Protractor
Correct answer: Plumb bob
A plumb bob uses gravity to establish a true vertical reference line for checking plumb alignment.
Question 3: When stripping insulation from large-gauge elevator control wiring, which tool should be used?
- Utility knife
- Wire stripper matched to wire gauge (Correct answer)
- Diagonal cutters
- Needle-nose pliers
Correct answer: Wire stripper matched to wire gauge
A wire stripper sized to the correct gauge removes insulation cleanly without nicking the conductor.
Question 4: Which measuring tool is used to verify that elevator guide rails are installed at the correct distance apart (span)?
- Steel tape measure (Correct answer)
- Dial indicator
- Feeler gauge
- Micrometer
Correct answer: Steel tape measure
A steel tape measure is used to verify the precise horizontal span between guide rails against engineering drawings.
Question 5: A technician needs to remove a corroded bolt in a tight space inside the pit. Which tool is best?
- Open-end wrench
- Socket wrench with extension (Correct answer)
- Adjustable wrench
- Pipe wrench
Correct answer: Socket wrench with extension
A socket wrench with an extension reaches deep or tight spaces while providing full torque on the bolt head.
Question 6: What tool is used to test for voltage presence before touching elevator control wiring?
- Multimeter set to DC voltage
- Non-contact voltage tester (Correct answer)
- Ohmmeter
- Clamp meter
Correct answer: Non-contact voltage tester
A non-contact voltage tester detects live voltage without touching the conductor, providing a quick safety check.
Question 7: Which hand tool is used to align and hold two elevator rail brackets together before bolting?
- C-clamp or bar clamp
- Vise-grip pliers
- Drift punch (Correct answer)
- Pry bar
Correct answer: Drift punch
A drift punch aligns bolt holes in steel brackets by being driven through the holes to draw them into registration.
