1. What is the primary purpose of personal protective grounding?
A. Improve system efficiency
B. Reduce line loss
C. Protect workers from accidental energization
D. Increase fault current
C
Personal protective grounding provides a low-resistance path to ground
to protect workers if a line becomes energized.
2. Minimum approach distance is primarily determined by which factor?
A. Weather conditions
B. Voltage level
C. Type of conductor
D. Pole material
B
Higher voltages require greater minimum approach distances to prevent
electrical flashover.
3. Which knot is most commonly used by linemen for securing tools aloft?
A. Square knot
B. Bowline
C. Sheet bend
D. Clove hitch
B
, The bowline creates a secure, non-slipping loop commonly used in line
work.
4. What PPE is required when working on or near energized lines?
A. Safety glasses only
B. Rubber insulating gloves and sleeves
C. Hard hat only
D. Steel-toe boots only
B
Rubber gloves and sleeves protect against electrical shock when working
near energized conductors.
5. A hot stick is primarily used to:
A. Measure voltage
B. Install crossarms
C. Maintain distance from energized parts
D. Test continuity
C
Hot sticks allow linemen to work on energized lines while maintaining
safe clearance.
6. What is the first step in pole-top rescue?
A. Administer CPR
B. Call emergency services
C. Secure the victim and yourself
D. Lower the victim immediately
C
Scene safety and securing both rescuer and victim is the top priority.
7. Which type of insulator is most commonly used on distribution lines?
A. Pin-type
B. Suspension
C. Strain
D. Shackle
A
Pin-type insulators are widely used in distribution systems.
, 8. What causes conductor sag to increase?
A. Lower temperature
B. Higher tension
C. Higher temperature
D. Shorter span
C
As temperature rises, conductors expand, increasing sag.
9. Which voltage is considered high voltage in line work?
A. Below 600 V
B. 600–1000 V
C. Above 1000 V
D. Above 120 V
C
High voltage is generally defined as greater than 1000 volts.
10.The primary function of a recloser is to:
A. Regulate voltage
B. Protect transformers
C. Automatically restore power after faults
D. Increase load capacity
C
Reclosers open during faults and reclose to restore service if the fault
clears.
11.What tool is used to tension conductors?
A. Come-along
B. Grip-all clamp
C. Wire brush
D. Crimping tool
A
Come-alongs apply controlled tension during stringing operations.
12.What hazard is most associated with step potential?
A. Contact with energized tools
B. Voltage difference between feet
