CUSP - T&D EXAM 2025 WITH 100%
CORRECT 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.
