EIAT and NEIEP Test Tools, Equipment and Installation 1 — Questions and Answers
Question 1: What tool is used to cut threads on the outside of a metal conduit or pipe?
- Tap
- Die (Correct answer)
- Reamer
- Hacksaw
Correct answer: Die
A die is used to cut external (male) threads on conduit, pipes, or rods, while a tap cuts internal (female) threads.
Question 2: What is a 'fish tape' used for in electrical installation?
- Sealing conduit ends from moisture
- Pulling wire through conduit or walls (Correct answer)
- Measuring conduit lengths
- Taping wire splices
Correct answer: Pulling wire through conduit or walls
A fish tape is a long flexible steel or fiberglass tape used to pull conductors through conduit or through wall cavities.
Question 3: Which type of drill bit is most suitable for drilling through masonry or concrete?
- Twist bit
- Spade bit
- Carbide-tipped masonry bit (Correct answer)
- Hole saw
Correct answer: Carbide-tipped masonry bit
Carbide-tipped masonry bits are designed to withstand the hardness of concrete, brick, and masonry without dulling quickly.
Question 4: The primary purpose of a conduit reamer is to:
- Cut conduit to length
- Remove burrs from the inside of cut conduit ends (Correct answer)
- Bend conduit at precise angles
- Thread conduit ends
Correct answer: Remove burrs from the inside of cut conduit ends
A reamer removes sharp burrs left on the inside of conduit after cutting, preventing damage to wire insulation during pull-through.
Question 5: A knockout punch is used to:
- Drive anchors into concrete
- Create clean holes in electrical enclosures and panels (Correct answer)
- Punch through drywall for box mounting
- Set nail anchors in masonry
Correct answer: Create clean holes in electrical enclosures and panels
A knockout punch set creates clean, precise holes in electrical panels, boxes, and enclosures for conduit entry without distorting the metal.
Question 6: What does a megohmmeter (megger) test?
- Voltage output of a circuit
- Insulation resistance of conductors and equipment (Correct answer)
- Continuity of a fuse
- Phase rotation of a motor
Correct answer: Insulation resistance of conductors and equipment
A megohmmeter (megger) applies high DC voltage and measures insulation resistance in megohms to detect deteriorating or damaged insulation.
