1. All 15-ampere and 20-ampere, 125-volt general-purpose receptacles in a new
dwelling are required to be:
A) Grounding-type only
B) Duplex-type only
C) GFCI-protected
D) Installed 6 inches from the floor
Correct Answer: C
Explanation: The CEC requires GFCI protection for all 15A and 20A, 125V receptacles in
dwelling units in specific locations such as bathrooms, kitchens, outdoors, and unfinished
basements. This is a standard safety requirement for new dwellings .
2. Each multi-wire branch circuit MUST be provided with a means to disconnect all
ungrounded conductors:
A) Continuously
B) Safely
C) Individually
D) Simultaneously
Correct Answer: D
Explanation: Multi-wire branch circuits require a means to disconnect all ungrounded
conductors simultaneously to prevent the risk of returning current on the neutral when
only one phase is disconnected .
,3. 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) 75%
C) 150%
D) 125%
Correct Answer: D
Explanation: For resistance welders, the overcurrent device may be set at up to 125% of
the conductor ampacity due to the intermittent nature of the load .
4. Which of the following is NOT allowed for connecting equipment grounding
conductors?
A) Machine screws
B) Terminal bars
C) Pressure connectors
D) Solder
Correct Answer: D
Explanation: Solder is not permitted for connecting equipment grounding conductors
because soldered joints can fail under high fault current conditions, creating a fire or shock
hazard .
5. 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) 6
B) 8
C) 4
D) 2
Correct Answer: D
*Explanation: The CEC limits the length of flexible cord from the supply point to a
tension take-up device to 2 feet (600 mm) to prevent strain on the connection points .*
,6. For a 14-gauge copper wire, the maximum overcurrent protection rating is _____
amps.
A) 30
B) 20
C) 15
D) 10
Correct Answer: C
Explanation: 14 AWG copper wire has a maximum overcurrent protection rating of 15
amperes under general use conditions. This is a fundamental code rule for conductor
sizing .
7. What is the minimum clearance required for overhead SERVICE-DROP
conductors over a roof with a slope of 6:12?
A) 3 feet
B) 4 feet
C) 8 feet
D) 6 feet
Correct Answer: B
*Explanation: For roofs with a slope of 4 in 12 or greater, the minimum vertical clearance
for service-drop conductors above the roof is 4 feet (1.2 meters) .*
8. _____ is defined as admitting close approach; not guarded by locked doors,
elevation, or other effective means.
A) Readily accessible
B) Isolated
C) Approachable
D) Accessible
Correct Answer: D
Explanation: "Accessible" means capable of being reached for operation, repair, or
inspection without the use of ladders or tools. This is a key CEC definition .
, 9. What is the minimum number of sealing fittings required for a 12-foot run of
horizontal conduit in a Class II, Division 1 location?
A) Four sealing fittings
B) One sealing fitting
C) Three sealing fittings
D) Two sealing fittings
Correct Answer: D
Explanation: In Class II, Division 1 locations (combustible dust), sealing fittings are
required on each conduit run entering an enclosure, typically at both ends of the run .
10. Fixed electric space heating loads shall be computed at _____ percent of the
total connected load.
A) 115%
B) 100%
C) 125%
D) 80%
Correct Answer: B
Explanation: Fixed electric space heating loads are calculated at 100% of the total
connected load, but the feeder load current cannot be less than the rating of the largest
branch circuit supplied .

11. The minimum trade size EMT required for a 45-foot run containing four #12
THHN/THWN, three #10 THHN/THWN, and two #6 THHN/THWN conductors is:
A) 1 inch
B) 1-1/4 inches
C) 3/4 inch
D) 1-1/2 inches
