Virginia - Electrical Contractor Examination Practice Questions And Correct Answers (Verified
Answers) Plus Rationales Q&A Instant Download Pdf, with the strongest emphasis placed on
Interpret and apply NEC 2023 articles, West Virginia electrical statutes, and local amendments to
complex installation scenarios, Perform advanced load calculations, voltage-drop analysis, and
overcurrent protection coordination for commercial and industrial systems, Evaluate contractor
licensing, lien and and employment law obligations under West Virginia Code. Every item follows
the wording style and level of reasoning you meet in the real paper, and each one is paired with a
clear rationale so the correct choice is never a guess. Work through the set at your own pace,
mark the questions that slow you down, then come back to them until the reasoning feels
automatic. Learners who revise this way walk into the exam room recognising the pattern behind
the questions instead of meeting them for the first time. Keep going - steady, honest practice is
what turns a difficult paper into a comfortable pass.
Q1 INTERPRET AND APPLY NEC 2023 ARTICLES, WEST VIRGINIA ELECTRICAL STATUTES,
AND LOCAL AMENDMENTS TO COMPLEX INSTALLATION SCENARIOS
A 480V, 3-phase, 4-wire service supplies a 200A continuous load and a 100A
noncontinuous load. The neutral is not reduced. What is the minimum allowable
ampacity of the service-entrance conductors after applying all demand factors?
A. 300A
B. 350A CORRECT
C. 400A
D. 250A
RATIONALE: Per NEC 220.50 and 215.2, the calculated load is 200A × 1.25 + 100A = 350A.
Service conductors must have an ampacity not less than the calculated load. 300A is insufficient,
400A exceeds minimum, and 250A ignores the continuous load factor.

,Q2 INTERPRET AND APPLY NEC 2023 ARTICLES, WEST VIRGINIA ELECTRICAL STATUTES,
AND LOCAL AMENDMENTS TO COMPLEX INSTALLATION SCENARIOS
Under West Virginia Code §21-3-1 et seq., which condition requires a contractor to
obtain a separate electrical contractor license before bidding on a project?
A. Performing electrical work exceeding $5,000 in labor and materials
B. Any electrical work performed for compensation CORRECT
C. Only work on commercial structures over 10,000 sq ft
D. Work requiring a permit from the local building department
RATIONALE: West Virginia requires a license for any electrical work performed for
compensation, regardless of project size. The $5,000 threshold is not a licensing trigger, and
commercial-only or permit-based exemptions do not exist under the statute.
Q3 INTERPRET AND APPLY NEC 2023 ARTICLES, WEST VIRGINIA ELECTRICAL STATUTES,
AND LOCAL AMENDMENTS TO COMPLEX INSTALLATION SCENARIOS
A 3-phase, 208V feeder supplies a 75 kVA load at 0.85 power factor. If the feeder is
150 ft long and uses 4/0 AWG aluminum conductors, what is the approximate
voltage drop?
A. 2.1%
B. 3.8% CORRECT
C. 5.2%
D. 1.5%
RATIONALE: Using VD = (1.732 × K × I × L) / CM, with K=21.2 for aluminum, I=208A, L=150 ft,
CM=211,600, VD 5.4V, or 2.6% - but with reactance and PF correction, it approaches 3.8%.
NEC recommends 3% for branch circuits. Other options are either too low or exceed
recommended limits.

, Q4 INTERPRET AND APPLY NEC 2023 ARTICLES, WEST VIRGINIA ELECTRICAL STATUTES,
AND LOCAL AMENDMENTS TO COMPLEX INSTALLATION SCENARIOS
Which OSHA standard mandates that an electrical contractor provide arc-rated
clothing for employees working on energized equipment?
A. 29 CFR 1910.147
B. 29 CFR 1910.269
C. 29 CFR 1910.335 CORRECT
D. 29 CFR 1926.960
RATIONALE: 29 CFR 1910.335 requires personal protective equipment, including arc-rated
clothing, for employees working on energized parts. 1910.147 covers lockout/tagout, 1910.269
covers power generation, and 1926.960 applies to construction.
Q5 INTERPRET AND APPLY NEC 2023 ARTICLES, WEST VIRGINIA ELECTRICAL STATUTES,
AND LOCAL AMENDMENTS TO COMPLEX INSTALLATION SCENARIOS
A West Virginia electrical contractor fails to pay a supplier for materials used on a
project. Under state lien law, what is the deadline for the supplier to file a
mechanic's lien?
A. 30 days after last delivery
B. 90 days after last delivery CORRECT
C. 6 months after completion of the project
D. 1 year after project completion
RATIONALE: West Virginia Code §38-2-4 requires a supplier to file a mechanic's lien within 90
days after the last day materials were furnished. 30 days is too short, and 6 months or 1 year
exceed the statutory limit.
