1.
In a 120 V circuit with a load drawing 15 A, what is the total power consumed?
A. 1800 W
B. 150 W
C. 800 W
D. 1200 W
Answer: A
Rationale: Power = Voltage × Current = 120 V × 15 A = 1800 W.
2.
Which part of the Canadian Electrical Code (CEC) outlines the general rules for conductor sizing
and overcurrent protection?
A. Rule 2
B. Rule 4
C. Rule 8
D. Rule 10
Answer: A
Rationale: CEC Rule 2 covers general requirements, including conductor sizing and protection.

3.
According to the CEC, the minimum size grounding conductor for a 100 A service must be
determined by:
A. The overcurrent protective device rating
B. The load power factor
C. The type of switch used
D. The type of load only
Answer: A
Rationale: Grounding conductor size is based on OCPD rating and code tables.
4.
A motor nameplate reads 10 HP at 230 V and 3 A. What is unusual about this nameplate data?
A. Horsepower and amperage do not correspond — the current is too low
B. The voltage is incorrect
C. The horsepower is too low
D. It is correct for a 10 HP motor
Answer: A
Rationale: A 10 HP motor at 230 V typically draws significantly more than 3 A — likely a misprint
or incorrect rating.

5.
What is the primary purpose of bonding conductors in an electrical installation?
A. Provide a path for fault current to clear overcurrent devices
B. Increase system voltage
C. Act as a neutral conductor
D. Reduce conduit fill
Answer: A
Rationale: Bonding ensures fault currents can return and clear quickly, improving safety.
6.
Which device is used to protect equipment from overcurrent due to short circuits and
overloads?
A. Circuit breaker
B. Voltage regulator only
C. Transformer
D. Capacitor
Answer: A
Rationale: Circuit breakers protect circuits from overcurrent conditions.
