Question 1
Under North Carolina electrical contractor licensing classifications, what
does an Unlimited classification permit a licensee to do?
A. Perform only residential electrical work
B. Perform electrical work only on projects below a specified dollar
amount
C. Perform only one specialized phase of electrical contracting
D. Engage in any electrical contracting project regardless of value
Rationale: The Unlimited classification is the broadest electrical
contractor classification in North Carolina. It permits the licensee to
engage in electrical contracting projects without the project-value
limitation applicable to lower classifications.
,Question 2
What minimum total experience is generally required for an applicant
seeking the Unlimited electrical contractor examination in North
Carolina?
A. 3,000 hours
B. 5,750 hours
C. 7,500 hours
D. 9,000 hours
Rationale: North Carolina's examination rules specify 9,000 hours of
experience for the Unlimited classification. At least 8,000 of those
hours must be primary experience, with the remaining experience
potentially being primary, secondary, or both.
Question 3
Of the experience required for the Unlimited classification, at least how
many hours must be primary experience?
A. 2,000 hours
B. 5,000 hours
C. 7,000 hours
D. 8,000 hours
,Rationale: The Unlimited classification requires at least 9,000 total
hours, of which at least 8,000 hours must consist of primary
experience involving direct installation of electrical wiring and
equipment governed by the NEC.
Question 4
Which code is incorporated into the North Carolina electrical licensing
rules as the National Electrical Code?
A. NFPA 10
B. NFPA 13
C. NFPA 70
D. NFPA 101
Rationale: NFPA 70 is the National Electrical Code (NEC). North
Carolina incorporates the NEC into the State Building Code, subject to
applicable North Carolina amendments.
Question 5
What is the primary purpose of an equipment grounding conductor?
A. To carry normal circuit current
B. To increase circuit voltage
C. To reduce conductor resistance
D. To provide a low-impedance path for fault current
, Rationale: An equipment grounding conductor provides a conductive
path for fault current so that overcurrent protection can operate
promptly and disconnect the faulty circuit.
Question 6
Which conductor normally carries the return current from a line-to-
neutral load in a single-phase circuit?
A. Equipment grounding conductor
B. Grounding electrode conductor
C. Bonding jumper
D. Grounded conductor
Rationale: The grounded conductor, commonly called the neutral,
normally carries current back toward the source from line-to-neutral
loads. It is distinct from the equipment grounding conductor, which
normally carries no load current.
Question 7
What is the primary purpose of bonding electrically conductive
equipment and enclosures?
A. Increase operating voltage
B. Reduce conductor ampacity
