CUSP - T&D Questions & Answers 150 Questions withCorrect Answers.
As per CAN/ULC S801, on an electrical distribution overhead utility line circuit,
verification of voltage absence can be achieved by: - Correct Answer Using an
approved voltage detector.
Isolation and tagging (no locks) is acceptable on an overhead distribution circuit
under some of the following conditions, EXCEPT for: - Correct Answer The isolation
can be operated from the ground directly at the base of a structure.
Isolation and tagging (no locks) is acceptable for an overhead distribution circuit
under some of the following conditions: - Correct Answer 1. The isolation point is a
physical and visual like a line cut or riser removed.
2. The isolation point can only be operated by the operating authority or qualified
worker.
3. The isolation point is protected from unauthorized access such as vertical height
spacing.
Consider that a circuit has been isolated, tagged and grounded. workers returning
the next day must: - Correct Answer Visually check grounds to verify they are in
good order, secure and test for voltage.
For lockout purposes, energy isolating devices shall be labelled or marked using a
standardized nomenclature and format to indicate their function. Identification shall
include: - Correct Answer The equipment type, energy type, and magnitude.
Utilities often use a permitting system due to special circumstances of which
conventional lockout is impracticable. The following is NOT a justified approach to
this process: - Correct Answer The isolation points are only simple single step
actions.
A high voltage utility or electrical company is authorized to use Complex Lockout (tag
permitting) under what regulatory condition: - Correct Answer A variance application
has been approved by the provincial authority.
Utilities often use a permitting system due to special circumstances of which
conventional lockout is impracticable. The following are justified approaches to this
process: - Correct Answer 1. The isolation points are located in remote areas with
difficult or restricted access.
2. The length of time to perform the lockout is impracticable.
3. Excessive numbers of persons required to lockout.
Work on a distribution line must consider the following items when performing
isolation and de-energizing of the circuit.: - Correct Answer 1. Whether there are
multiple sources of energy (loop feed) on the circuit.
2. Is the line isolating device capable of interrupting load.
3. Is the line to be subject to inductive or capacitive charge.
, According to the CAN/ULC S801, what is the LEAST DESIRABLE type of fall
protection: - Correct Answer Fall Arrest System (FAS)
Within Z259.14 standards fall restriction equipment (FRE) may only be leather in
subcomponents or elements that are NOT exposed to: - Correct Answer A dynamic
load.
As per Z259 standards, energy absorbing lanyards shall be classified according to
their ability to absorb the kinetic energy from a fall as follows: - Correct Answer Class
E4 (4.0 kN) and Class E6 (6.0 kN) energy absorbing lanyards.
Assuming that the fall protection system is correctly being used, in what scenario
might the worker still contact the ground if they fell: - Correct Answer Working 16 feet
up in a bucket truck on distribution secondary services using a six foot shock
absorbing lanyard, connected to the approved bucket anchor.
What is NOT defined as a requirement of temporary vertical life lines as per Z259
standards: - Correct Answer 100% polypropylene fibers provide the greatest
breaking strength.
Requirements of temporary vertical life lines, as per Z259 standards: - Correct
Answer 1. Shall be made from synthetic fibers with breaking strength of 27 kN or
greater.
2. They shall be free of splices and knots, except at the terminations.
3. They shall be installed to protect against abrasion and sharp edges.
Working on an energized lattice tower requires emergency response consistent with
the associated hazards. What is NOT required as part of the emergency planning: -
Correct Answer Daily practice of tower rescue method.
Working on an energized lattice tower requires emergency response consistent with
the associated hazards, including: - Correct Answer 1. A means to contact the
operating authority to de-energize the circuit.
2. Rescue equipment readily available to quickly and safely lower the worker.
3. Regular rescue practices on tower rescue at an appropriate frequency.
Z259.14 wooden pole choker devices that are designed and tested to restrict a
workers fall distance under dry, wet, and icy conditions are classified as: - Correct
Answer Type AB device.
The voltage limits and mechanical strength of a live line tool is best specified by: -
Correct Answer The manufacturers requirements.
Live line tools can be modified to meet the needs of the work. What is NOT an
acceptable strategy for tool modification: - Correct Answer A utility worker has
evaluated the tool modification and approved the change.
Live line tools can be modified to meet the needs of the work. Acceptable strategies
for tool modification include: - Correct Answer 1. Changes to the tool do not violate
other applicable standards.
