1. What is the primary purpose of a hot stick in electric line work?
A. To measure voltage
B. To safely handle energized equipment from a distance
C. To cut trees near power lines
D. To ground circuits
Hot sticks allow lineworkers to manipulate live electrical equipment
safely from a distance, minimizing the risk of electrical shock.
2. Which type of current is most commonly transmitted on high-voltage
utility lines?
A. Direct current (DC)
B. Alternating current (AC)
C. Pulsed current
D. Static current
AC is used because it can be easily transformed to different voltages
and efficiently transmitted over long distances.
3. What is the main purpose of a fuse in a power distribution system?
A. To increase voltage
B. To store energy
C. To protect equipment from overcurrent
D. To regulate frequency
Fuses interrupt the flow of current when it exceeds safe levels,
preventing damage to equipment and reducing fire hazards.
,4. Which OSHA regulation primarily governs electric utility linework
safety?
A. OSHA 1910 Subpart D
B. OSHA 1910 Subpart R
C. OSHA 1910 Subpart P
D. OSHA 1910 Subpart N
Subpart R specifically addresses the safety requirements for electric
power generation, transmission, and distribution.
5. When climbing a utility pole, what is the correct placement of climbing
gaffs?
A. On the outer side of boots
B. On the inside of boots
C. Properly strapped to the boots and facing inward for secure grip
D. On the knees for extra support
Climbing gaffs must be correctly positioned to ensure secure contact
with the pole and prevent slipping.
6. Which type of grounding system provides a direct path for fault
current to the earth?
A. Isolated grounding
B. Floating grounding
C. Solid grounding
D. Neutral grounding
Solid grounding ensures fault currents have a low-resistance path to
the earth, improving safety and reducing equipment damage.
7. What is the minimum approach distance for a qualified lineworker
from a 15 kV energized conductor?
A. 1 foot
B. 2 feet
C. 4 feet
D. 3 feet
OSHA specifies minimum approach distances based on voltage levels
to prevent accidental contact with energized conductors.
8. Which tool is used to test if a line is de-energized?
A. Screwdriver
B. Voltage regulator
, C. Clamp meter
D. Voltage detector
Voltage detectors confirm the absence of voltage before
maintenance, ensuring worker safety.
9. In electric utility systems, what is the primary purpose of a
transformer?
A. To store electrical energy
B. To provide surge protection
C. To step voltage up or down
D. To measure current
Transformers adjust voltage levels for efficient transmission or safe
distribution to customers.
10. What does an insulator do on a utility pole?
A. Conduct electricity
B. Ground the line
C. Prevent unwanted current flow to the pole
D. Measure voltage
Insulators isolate electrical conductors from poles or crossarms,
preventing leakage and shorts.
11. Which class of lineworker gloves is rated for 15 kV maximum
use?
A. Class 0
B. Class 1
C. Class 2
D. Class 4
Class 2 rubber gloves are tested for up to 17,000 volts AC, making
them suitable for 15 kV systems.
12. What is the purpose of a hot-line clamp?
A. To measure current
B. To cut conductors
C. To connect temporary equipment to an energized line safely
D. To ground a line
Hot-line clamps allow equipment or tools to be securely attached to
live conductors while minimizing risk.
