/instant pdf 2026/2027 version updated this month
1. What is the primary responsibility of an Electrical Field Safety Representative
(FSR)?
A. To design all electrical systems
B. To oversee electrical work and ensure compliance with applicable safety requirements
C. To replace the electrical inspector
D. To approve building permits
Correct answer: B. To oversee electrical work and ensure compliance with applicable safety
requirements
Rationale: An FSR is responsible for exercising oversight and ensuring electrical work is
performed in accordance with applicable requirements.
2. Before beginning electrical work, the first priority should be to:
A. Energize the circuit to test it
B. Identify hazards and establish safe work procedures
C. Remove all overcurrent protection
D. Bypass the disconnecting means
Correct answer: B. Identify hazards and establish safe work procedures
Rationale: Hazard identification and planning are essential before electrical work begins.
3. The purpose of a permit is primarily to:
A. Eliminate the need for inspection
B. Authorize regulated work and support compliance with safety requirements
C. Replace the Canadian Electrical Code
D. Allow unqualified persons to perform any electrical work
Correct answer: B. Authorize regulated work and support compliance with safety requirements
Rationale: Permits help ensure regulated electrical work is properly authorized and subject to
applicable requirements.
4. Electrical installations must generally be installed in accordance with:
A. Personal preference
B. Applicable electrical safety legislation and the adopted electrical code
,C. Manufacturer advertising only
D. Verbal instructions from a property owner
Correct answer: B. Applicable electrical safety legislation and the adopted electrical code
Rationale: Electrical work must comply with the governing legislation, regulations, adopted
code, and applicable standards.
5. What is the main purpose of bonding?
A. To increase circuit voltage
B. To provide a low-impedance path for fault current
C. To eliminate the need for grounding
D. To reduce conductor size
Correct answer: B. To provide a low-impedance path for fault current
Rationale: Bonding helps ensure fault current can return to the source and operate the
overcurrent protective device.
6. The grounding conductor is intended primarily to:
A. Carry normal load current continuously
B. Provide a path for fault current and establish a reference to earth where required
C. Replace the neutral conductor
D. Increase the circuit's operating voltage
Correct answer: B. Provide a path for fault current and establish a reference to earth where
required
Rationale: Grounding and bonding systems contribute to fault clearing and electrical safety.
7. An overcurrent protective device is intended to protect against:
A. Excessive current that can damage conductors or equipment
B. All possible electrical hazards
C. Water damage
D. Mechanical vibration only
Correct answer: A. Excessive current that can damage conductors or equipment
Rationale: Fuses and circuit breakers protect circuits from overloads and short-circuit conditions
within their ratings.
8. A circuit breaker should generally be selected based on:
, A. The colour of the panel
B. The circuit conductors, load, equipment ratings, and applicable code requirements
C. The homeowner's preference only
D. The length of the building
Correct answer: B. The circuit conductors, load, equipment ratings, and applicable code
requirements
Rationale: Protective devices must be properly coordinated with the circuit and equipment they
protect.
9. What is the purpose of a disconnecting means?
A. To provide a means of isolating equipment or a circuit from its source of supply
B. To increase current flow
C. To replace overcurrent protection
D. To eliminate the need for maintenance
Correct answer: A. To provide a means of isolating equipment or a circuit from its source of
supply
Rationale: Disconnects allow equipment or circuits to be isolated for operation, maintenance, or
emergency purposes.
10. Before working on an electrical circuit, the safest practice is to:
A. Assume the circuit is de-energized
B. De-energize, lock out where applicable, and verify absence of voltage
C. Touch the conductor with a bare hand
D. Remove the circuit breaker label
Correct answer: B. De-energize, lock out where applicable, and verify absence of voltage
Rationale: Electrical isolation must be verified before work begins.
11. A conductor's ampacity is affected by:
A. Conductor size, insulation, installation conditions, and applicable correction factors
B. The colour of the conductor only
C. The brand of the panel only
D. The number of rooms in the building
Correct answer: A. Conductor size, insulation, installation conditions, and applicable correction
factors
