FOURTH PERIOD AIT
200 QUESTIONS WITH CORRECT ☑VERIFIED
ANSWERS AND RATIONALES
SECTION 1: CANADIAN ELECTRICAL CODE (CEC)
& REGULATIONS
1. According to the Canadian Electrical Code,
the primary purpose of bonding is to:
• A. Increase circuit resistance for safety
, • B. Ensure continuity and provide a low-
impedance path for fault current
• C. Reduce voltage drop in conductors
• D. Balance three-phase loads
Correct ☑VERIFIED ANSWER: B
Rationale: 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.
2. Which edition of the Canadian Electrical
Code is currently in force in Alberta as of April
1, 2025?
• A. 24th Edition
• B. 25th Edition
, • C. 26th Edition (CSA C22.1-24)
• D. 27th Edition
Correct ☑VERIFIED ANSWER: C
Rationale: 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

• A. 50%
• B. 65%
• C. 70%
• D. 75%
, Correct ☑VERIFIED ANSWER: C
Rationale: 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%.

conductor size permitted for a branch circuit
supplying a 15 A lighting load?
• A. 18 AWG
• B. 16 AWG
• C. 14 AWG
• D. 12 AWG
Correct ☑VERIFIED ANSWER: C
Rationale: CEC Table 2 specifies that 14 AWG
copper is the minimum conductor size for 15 A
