Alberta Electrician Fourth Period AIT Exam
Exam Coverage Summary
The Alberta Electrician Fourth Period technical training represents the final level of apprenticeship
education before challenging the Interprovincial Red Seal Exam . Fourth Period training typically runs for
10 weeks and builds upon the foundational knowledge from Periods 1 through 3 . Key subject areas
include advanced AC theory (three-phase and single-phase), electrical system analysis and
troubleshooting, Canadian Electrical Code (CEC) applications, motor controls, power distribution, and
system protection . Students must achieve a minimum cumulative weighted average of 65% across
courses, with no course mark below 50%, and must attain a 70% passing mark on the AIT Period Final
Exam to successfully complete the period . Upon successful completion of Fourth Period, apprentices
are eligible to challenge the Interprovincial Red Seal Exam to become a journeyperson .
Question 1
What is the minimum passing grade required on the Alberta AIT Fourth Period final exam to pass the
period of training?
A) 50%
, Page 2 of 122
B) 65%
C) 70%
D) 75%
Correct Answer: C
Summary Rationale: Apprentices must achieve a 70% passing mark on the AIT Period Final Exam to pass
their period of training, in addition to meeting course requirements .
Question 2
An apprentice has completed Fourth Period technical training and passed the AIT exam. What is the next
step in their career progression?
A) Begin Period 5 technical training
B) Challenge the Interprovincial Red Seal Exam
C) Apply for a master electrician license
D) Complete an additional 2,000 hours of on-the-job training
Correct Answer: B
Summary Rationale: Upon successful completion of the Fourth Period, apprentices may challenge the
Interprovincial Red Seal Exam to earn their Journeyperson Certificate .

apprenticeship training?
A) 8 weeks
B) 10 weeks
C) 12 weeks
D) 14 weeks
Correct Answer: B
Summary Rationale: Fourth Period apprenticeship training requires 10 weeks of classroom instruction,
compared to 8 weeks for Periods 1 and 2 .
Question 4
A Fourth Period apprentice is studying three-phase power systems. What is the phase difference
between lines in a balanced three-phase system?
A) 60 degrees
B) 90 degrees
C) 120 degrees
D) 180 degrees
, Page 4 of 122
Correct Answer: C
*Summary Rationale: In a balanced three-phase system, the three voltages are separated by 120
electrical degrees .*
Question 5
What is the formula for calculating apparent power in a three-phase system?
A) P = V × I × PF
B) S = V × I × √3
C) Q = V × I × sinθ
D) P = I² × R
Correct Answer: B
*Summary Rationale: Apparent power (S) in a balanced three-phase system is calculated as line voltage
multiplied by line current multiplied by the square root of 3 (√3) .*
Question 6
An electrician measures 277 V phase-to-neutral in a three-phase system. What is the approximate
phase-to-phase voltage?
A) 277 V
