1. A conduit system is being installed to protect electrical conductors
from physical damage. Which statement BEST describes the
primary purpose of the conduit?
A. To increase the voltage rating of the conductors
B. To provide a protected pathway for electrical conductors
C. To eliminate the need for overcurrent protection
D. To increase the current-carrying capacity of the conductors
Answer: B. To provide a protected pathway for electrical
conductors
Rationale: Conduit primarily provides a mechanical pathway and
protection for conductors while also helping organize and route the
wiring system. It does not inherently increase conductor ampacity,
voltage rating, or replace overcurrent protection.
2. An electrician is preparing to pull several conductors through a
long conduit run containing multiple bends. Which condition would
generally make the pulling operation MORE difficult?
A. Increasing the conduit diameter
B. Reducing the number of bends
C. Increasing the number and severity of bends
D. Using properly sized pulling equipment
1
,Answer: C. Increasing the number and severity of bends
Rationale: Every bend introduces additional friction and changes the
direction of the pulling force. Multiple or severe bends can
substantially increase pulling tension and may require appropriate
pulling equipment, lubrication, or an intermediate pull point.
3. Which tool is specifically designed to create bends in many types
of electrical conduit?
A. Conduit bender
B. Lineman's pliers
C. Cold chisel
D. Pipe wrench
Answer: A. Conduit bender
Rationale: A conduit bender is designed to make controlled bends at
specified angles while maintaining the conduit’s usable interior
pathway. A pipe wrench is intended primarily for gripping and turning
threaded pipe and should not be substituted for a conduit bender.
4. A worker needs to make a 90-degree bend in electrical metallic
tubing (EMT). What is the most important reason for making the
bend properly rather than sharply crushing the tubing?
A. Proper bending preserves the conduit pathway and conductor-pulling
characteristics
B. Proper bending eliminates the need for fittings
C. Proper bending increases conductor resistance
D. Proper bending makes the conductors heavier
Answer: A. Proper bending preserves the conduit pathway and
conductor-pulling characteristics
2
,Rationale: Excessive deformation can reduce the interior area,
damage conductor insulation during installation, and make pulling
conductors substantially more difficult. A proper bend maintains the
integrity and usability of the raceway.
5. A conduit run requires a bend to change direction. The electrician
wants to avoid excessive pulling tension. Which approach is
generally preferable?
A. Make one extremely sharp bend
B. Use properly planned bends and fittings within permitted limits
C. Flatten the conduit at the bend
D. Increase the number of random bends
Answer: B. Use properly planned bends and fittings within
permitted limits
Rationale: Raceway layout should be planned so that bends are
smooth, controlled, and within applicable requirements. Good
planning reduces pulling difficulty and helps prevent conductor
damage.
6. What is the primary purpose of a conduit reamer after cutting
metallic conduit?
A. To increase the conduit diameter
B. To remove sharp edges and burrs from the cut end
C. To electrically insulate the conduit
D. To reduce the length of the conduit
Answer: B. To remove sharp edges and burrs from the cut end
3
, Rationale: Cutting metallic conduit can leave sharp edges that can
damage conductor insulation. Reaming removes those edges and
creates a smoother entry for conductors and fittings.
7. An apprentice cuts a piece of metal conduit and immediately
begins pulling wire through it without removing the burrs. What is
the greatest concern?
A. The conductors may become too short
B. The conduit may become nonmetallic
C. Sharp edges may damage conductor insulation
D. The circuit voltage will automatically increase
Answer: C. Sharp edges may damage conductor insulation
Rationale: Burrs are a significant mechanical hazard to wire
insulation. Damaged insulation can eventually expose energized
conductors and create shock, short-circuit, or fault hazards.
8. A raceway contains electrical conductors. Why should conductors
generally be pulled carefully rather than dragged aggressively?
A. Excessive pulling can damage conductor insulation
B. Aggressive pulling increases conductor voltage
C. Pulling force has no effect on conductors
D. Aggressive pulling improves conductor insulation
Answer: A. Excessive pulling can damage conductor insulation
Rationale: Excessive pulling tension can stretch, scrape, or otherwise
damage conductor insulation. Proper pulling practices protect the
conductor and help maintain the integrity of the completed
installation.
