1. What is the primary purpose of personal protective grounding when
working on a de-energized distribution line?
A. To comply with OSHA paperwork requirements
B. To create a low-impedance path to dissipate fault current and
protect workers
C. To reduce the life span of grounding equipment
D. To increase the load carrying capacity of the line
Personal protective grounding is applied to establish a
low-impedance path for fault current so that inadvertent
re-energization does not result in dangerous potential differences,
thereby protecting workers.
2. Which of the following voltage classes typically requires insulated
rubber gloves with leather protectors for live line work?
A. 0–300 V
B. 300–1,000 V
C. Over 1,000 V
D. Only voltages less than 50 V
For voltages over 1,000 V, insulated rubber gloves with leather
, protectors are required to provide adequate protection against
electric shock during live line work.
3. In South Carolina, what document outlines safety standards for
electrical linework practices?
A. Federal Motor Carrier Safety Administration (FMCSA) handbook
B. South Carolina Motorcycle Safety Manual
C. Occupational Safety and Health Administration (OSHA) 29 CFR
Part 1910 and 1926
D. Environmental Protection Agency (EPA) guidelines
OSHA standards in 29 CFR Parts 1910 and 1926 contain the safety
requirements and practices specific to electrical and construction
work, forming the basis of safe linework practices.
4. When climbing a wood pole, what is the minimum distance required
between gaff points on your climbing boots?
A. 4 inches
B. 6 inches
C. 8 inches
D. 10 inches
OSHA and industry safety standards require spacing between gaff
points to be at least 6 inches to provide stability and reduce the risk
of slippage during pole climbing.
5. What is the function of a hot stick in electrical linework?
A. To lift heavy transformers
B. To measure voltage exclusively
C. To allow workers to perform actions on energized conductors at a
safe distance
D. To ground the system permanently
A hot stick enables a lineworker to manipulate energized components
, from a distance, minimizing direct contact with live conductors for
safety.
6. Which conductor configuration is most likely used on a typical rural
primary distribution line?
A. Delta three-phase with grounded neutral
B. Single phase with neutral
C. Underground direct buried three-phase
D. Series capacitor bank only
Single phase with neutral is commonly used in rural areas due to
lower load and simpler distribution requirements.
7. The National Electrical Safety Code (NESC) primarily governs which of
the following?
A. Household wiring
B. Automotive electrical systems
C. Utility electric supply and communications lines external to
buildings
D. Electronic device circuit design
The NESC provides standards for the safety of electric supply and
communication lines outside buildings, focusing on their
construction, operation, and maintenance.
8. In overhead line construction, what determines the required pole
height?
A. Color of the pole
B. Type of soil only
C. Line voltage, clearances, span length, and terrain conditions
D. Number of linemen on the crew
Pole height must accommodate proper clearances, span lengths,
voltage class, and terrain to ensure safety and compliance with
codes.
