CUSP - T&D Exam
Questions & Answers 150 Questions
with Correct Answers.
1. As per CAN/ULC S801, on an electrical distribution overhead utility line
circuit, verification of voltage absence can be achieved by:
Ans: Using an approved voltage detector.
2. Isolation and tagging (no locks) is acceptable on an overhead distribution
circuit under some of the following conditions, EXCEPT for:
Ans: The isolation can be operated from the ground directly at the base of a
structure.
3. Isolation and tagging (no locks) is acceptable for an overhead distribution
circuit under some of the following conditions:
Ans: 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.
4. Consider that a circuit has been isolated, tagged and grounded. workers
returning the next day must:
Ans: Visually check grounds to verify they are in good order, secure and test for
voltage.
5. For lockout purposes, energy isolating devices shall be labelled or marked
using a standardized nomenclature and format to indicate their function.
Identification shall include:
Ans: The equipment type, energy type, and magnitude.
6. 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:
Ans: The isolation points are only simple single step actions.
7. A high voltage utility or electrical company is authorized to use Complex
Lockout (tag permitting) under what regulatory condition:
Ans: A variance applica- tion has been approved by the provincial authority.
8. Utilities often use a permitting system due to special circumstances of
which conventional lockout is impracticable. The following are justified ap-
proaches to this process:
Ans: 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.
9. Work on a distribution line must consider the following items when per-
forming isolation and de-energizing of the circuit.:

, Ans: 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.
10. According to the CAN/ULC S801, what is the LEAST DESIRABLE type of
fall protection:
Ans: Fall Arrest System (FAS)
