Alberta Master Electrician
Certification: 200 Practice Exam
Questions and Detailed Answer
Explanations[100% Correct\Verified]
1. What is the primary purpose of the Canadian Electrical
Code (CEC)?
A) To provide construction guidelines for buildings
B) To regulate electrical pricing
C) To ensure safe electrical installations
D) To certify electricians
Answer: C
Rationale: The CEC establishes safety standards for electrical
installations to protect people and property. It is a safety
standard, not a construction or pricing guide .
2. What does the term "ampacity" refer to?
A) Voltage drop
B) The current-carrying capacity of a conductor
C) The resistance of a wire
D) The power rating of a device
Answer: B
Rationale: Ampacity is defined in the CEC as the maximum
current, in amperes, that a conductor can carry continuously
, under specified conditions without exceeding its temperature
rating .
3. Under the Alberta Safety Codes Act, who is authorized to
obtain electrical permits (excluding homeowners)?
A) Any Journeyman Electrician
B) A Master Electrician with a Certificate of Competency
C) A Safety Codes Officer
D) The Electrical Contractors Association of Alberta (ECAA)
Answer: B
Rationale: Only a certified Master Electrician or an electrical
contractor employing a certified Master Electrician is authorized
to pull electrical permits in Alberta .
4. What is the standard color code for grounding conductors
in Alberta?
A) Red
B) Blue
C) Green or green with yellow stripe
D) White
Answer: C
Rationale: Grounding conductors are green or green/yellow to
distinguish them from current-carrying conductors. This prevents
dangerous misidentification during installation and maintenance .
5. What is the minimum size copper grounding electrode
conductor for a 200-ampere service?
A) 4 AWG
, B) 6 AWG
C) 8 AWG
D) 10 AWG
Answer: B
Rationale: According to the CEC, a 200-ampere service requires a
minimum 6 AWG copper grounding electrode conductor .
6. All 15 and 20 ampere, 125 volt, general-purpose
receptacles in a new dwelling are required to be:
A) Grounding-type
B) Duplex-type
C) GFCI-protected
D) Tamper-resistant
Answer: D
Rationale: The CEC requires that all 15 and 20 ampere, 125 volt,
general-purpose receptacles in a new dwelling be tamper-
resistant for enhanced safety against electric shock .
7. Each multi-wire branch circuit MUST be provided with a
means to disconnect all ungrounded conductors:
A) Continuously
B) Safely
C) Individually
D) Simultaneously
Answer: D
Rationale: Each multi-wire branch circuit must be provided with a
means to disconnect all ungrounded conductors simultaneously
to ensure safe disconnection .
, 8. What is the maximum percentage of the conductor rating
at which an overcurrent device must be set for conductors
supplying a resistance welder?
A) 100%
B) 125%
C) 150%
D) 200%
Answer: C
Rationale: The overcurrent device for a resistance welder must be
set at no more than 150% of the conductor rating to
accommodate the high inrush currents typical of such equipment .
9. Where flexible cord is connected to the building ceiling
with a suitable "tension take-up device," the maximum length
of the cord from the supply joint to the take-up device is _____
feet.
A) 2
B) 4
C) 6
D) 8
Answer: C
Rationale: When a flexible cord is connected to the building
ceiling with a suitable tension take-up device, the maximum
length from the supply joint to the take-up device is 6 feet .
10. For attics, underfloor spaces, utility rooms, and basements
in all occupancies, at least _____ lighting outlet(s) containing a
switch or controlled by a wall switch shall be installed where
