Introduction
This comprehensive examination is designed to rigorously assess the knowledge and practical skills required of a
professional Electrical Inspector in British Columbia. The content draws heavily from the Canadian Electrical Code,
Part I, and integrates foundational electrical theory with critical, real-world application. Candidates will be evaluated
,on their ability to interpret regulatory requirements, identify unsafe conditions, and make sound decisions in complex
scenarios. The assessment utilizes a combination of multiple-choice and situational questions to test not only recall of
specific rules but also the deeper understanding and judgment necessary to ensure public safety and compliance in the
field.
SECTION ONE: QUESTIONS 1–50
1. According to the Canadian Electrical Code, what is the minimum clearance required for a service drop
conductor passing over a residential driveway?
A. 3.5 meters
B. 4.0 meters
C. 5.0 meters
D. 6.0 meters
🟢 Correct Answer: C. 5.0 meters
🔴 Explanation: Rule 6-112 specifies that the minimum clearance for service drop conductors over a driveway or
residential street is 5.0 meters.
,2. An electrical inspector is reviewing a plan for a commercial kitchen. What is the minimum number of branch
circuits required for the receptacles serving the countertop surfaces in this area?
A. One circuit is sufficient.
B. Two circuits are required.
C. One circuit for every 1.5 meters of countertop.
D. The number of circuits is determined by the total connected load.
🟢 Correct Answer: D. The number of circuits is determined by the total connected load.
🔴 Explanation: While the CEC has specific rules for residential kitchens, commercial kitchens require a calculation
based on the connected load, not a fixed number of circuits.
3. Which of the following is a recognized method for providing grounding for a separately derived system, such
as a transformer?
A. Connecting the neutral to a metal water pipe.
B. Connecting the neutral to the building steel.
C. Connecting the neutral to a grounding electrode.
D. Connecting the neutral to the equipment grounding conductor.
🟢 Correct Answer: C. Connecting the neutral to a grounding electrode.
, 🔴 Explanation: Rule 10-204 requires that a separately derived system have its neutral conductor connected to a
grounding electrode.
4. What is the maximum allowable voltage drop for a branch circuit supplying a sensitive piece of electronic
equipment, as recommended by the CEC?
A. 1%
B. 3%
C. 5%
D. 10%
🟢 Correct Answer: B. 3%
🔴 Explanation: The CEC recommends that for sensitive equipment, the voltage drop should not exceed 3% for the
branch circuit, and a total of 5% including the feeder.
5. A 200-ampere residential service is being installed. What is the minimum size for the grounding conductor for
the service entrance?
A. #6 AWG copper
B. #4 AWG copper
