1. What is the minimum size copper bonding conductor for a 100A
service?
A. No. 8 AWG
B. No. 6 AWG
C. No. 4 AWG
D. No. 2 AWG
Rationale: Bonding conductor size is based on service ampacity; 100A
requires No. 6 AWG copper.
2. According to the CEC, what is the maximum number of 90° bends
allowed in a single conduit run?
A. Two
B. Three
C. Four
D. Five
Rationale: The code limits total bends to 360°, which equals four 90°
bends.
3. The purpose of a drip loop at service entrances is to:
,A. Reduce conductor resistance
B. Prevent water from entering equipment
C. Increase mechanical strength
D. Provide additional clearance
Rationale: Drip loops route water away from service raceways and
equipment.
4. What is the standard frequency of AC power in Canada?
A. 50 Hz
B. 60 Hz
C. 75 Hz
D. 120 Hz
Rationale: North American utility systems operate at 60 Hz.
5. A Class B fire involves:
A. Wood and paper
B. Flammable liquids
C. Energized electrical equipment
D. Combustible metals
Rationale: Class B refers to flammable liquids and gases.
6. Which device protects against ground faults?
A. Breaker
B. Fuse
C. GFCI
D. Contactor
Rationale: GFCIs detect low-level ground faults and trip quickly.
, 7. Parallel resistances always result in a total resistance that is:
A. Higher than the highest resistor
B. Equal to the average resistor
C. Lower than the smallest resistor
D. Equal to the sum of resistors
Rationale: Parallel circuits decrease total resistance.
8. The main purpose of a transformer is to:
A. Convert AC to DC
B. Change voltage levels
C. Change frequency
D. Increase current without changing voltage
Rationale: Transformers raise or lower AC voltage levels.
9. What is used to test insulation resistance?
A. Voltmeter
B. Ohmmeter
C. Megger
D. Clamp meter
Rationale: Meggers supply high voltage for accurate insulation resistance
testing.
10. Aluminum conductors must be terminated with:
A. Standard lugs
B. Brass terminals
C. AL/CU or AL terminals
D. Plastic connectors
Rationale: Aluminum requires approved AL/CU or AL-rated terminals for
safe contact.
