Question 1
According to the Canadian Electrical Code, what is the primary purpose of bonding in an
electrical installation?
A) To increase circuit resistance for safety purposes
B) To ensure continuity and provide a low-impedance path for fault current to operate
overcurrent protection devices
C) To reduce voltage drop in conductors
D) To balance three-phase loads
Answer: B - Bonding ensures fault current has a safe path to ground for protective
device operation . The CEC requires bonding to establish an effective ground-fault
current path that will allow circuit breakers or fuses to operate quickly when a fault
occurs.
Question 2
Which section of the Canadian Electrical Code specifically addresses grounding and
bonding requirements?
A) Section 8
B) Section 10
C) Section 12
D) Section 26
Answer: B - Section 10 of the CEC covers grounding and bonding requirements .
,Question 3
Which edition of the Canadian Electrical Code is currently in force in Alberta (as of April
2025)?
A) C22.1-21 (25th Edition)
B) C22.1-24 (26th Edition)
C) C22.1-27 (27th Edition)
D) C22.1-18 (24th Edition)
Answer: B - The CSA C22.1-24 Canadian Electrical Code (26th Edition) was declared in
force in Alberta on April 1, 2025. The 25th Edition was in force from February 1, 2022 to
March 31, 2025 .
Question 4
TRUE OR FALSE: The Canadian Electrical Code is a design specification and instruction
manual for untrained persons.
A) True
B) False
Answer: B (False) - The Canadian Electrical Code is not intended as a design
specification nor as an instruction manual for untrained persons . It establishes safety
standards for electrical installations but requires professional interpretation.
Question 5
What is the minimum passing grade required on the Alberta AIT Fourth Period final
exam to pass the period of training?
A) 50%
B) 65%
C) 70%
D) 75%
Answer: C - Apprentices must achieve a 70% passing mark on the AIT Period Final Exam
to pass their period of training . This is in addition to meeting course requirements with
a minimum cumulative weighted average of 65%.
,Question 6
Which section of the CEC contains general rules that apply to all installations?
A) Sections 0, 2, 4, 6, 8, 10, 12, 14, 16, and 26
B) Sections 20-30 only
C) Sections 44-66 only
D) Sections 72-86 only
Answer: A - Sections 0, 2, 4, 6, 8, 10, 12, 14, 16, and 26 contain general rules that apply
to all installations . Supplementary sections deal with specific locations or situations.
Question 7
TRUE OR FALSE: When interpreting the Canadian Electrical Code, rules found in
supplementary sections amend or supersede the rules in general sections of the Code.
A) True
B) False
Answer: A (True) - When interpreting the requirements for a particular installation,
rules found in supplementary sections of the Code amend or supersede the rules in
general sections . This is why Code interpretation requires understanding of both
general and supplementary sections.
Question 8
According to the CEC, what is the minimum size conductor permitted for a branch
circuit supplying a 15 A lighting load?
A) 18 AWG
B) 16 AWG
C) 14 AWG
D) 12 AWG
Answer: C - CEC Table 2 specifies that 14 AWG copper is the minimum conductor size
for 15 A branch circuits in most applications . Conductors must be sized to carry the
load without exceeding their ampacity.
, Question 9
According to the Alberta Safety Codes Act, who is responsible for obtaining electrical
permits for electrical work?
A) The electrician performing the work
B) The property owner
C) The permit holder (typically the contractor or homeowner)
D) The electrical inspector
Answer: C - The permit holder (typically the contractor or homeowner) is responsible
for obtaining electrical permits . The Safety Codes Act requires permits for most
electrical work to ensure compliance with the CEC.
Question 10
According to the CEC, what is the maximum recommended voltage drop for a feeder
and branch circuit combined?
A) 2%
B) 3%
C) 5%
D) 7%
Answer: C - CEC Section 8-102 recommends limiting voltage drop to 5% for a feeder
and branch circuit combined . For branch circuits alone, the recommendation is 3%.
Question 11
Which section of the CEC addresses wiring methods and conductor installation?
A) Section 10
B) Section 12
C) Section 20
D) Section 26
