Worked Sample Questions

Question 1 — Service and Feeders

A retail space is 8,000 sq ft. The lighting load is calculated at 3.5 VA per square foot. What is the calculated lighting load?

• A. 26,500 VA
• B. 29,000 VA
• C. 25,000 VA
• D. 28,000 VA ✓

Why D is correct: Multiply the area by the unit load: 8,000 × 3.5 = 28,000 VA. The 3.5 VA/sq ft unit load for retail/stores comes from NEC 2020 Table 220.12. This is a direct multiplication — no demand factor applies at this step. Candidates lose points here by applying a demand factor before the problem calls for one, or by misreading the square footage.

Question 2 — Grounding and Bonding

An equipotential bonding grid is required around outdoor pools. How far must it extend from the pool edge?

• A. 18 inches
• B. 24 inches
• C. 36 inches ✓
• D. 48 inches

Why C is correct: NEC 2020 Section 680.26(B)(2) requires the equipotential bonding for perimeter surfaces to extend 3 feet (36 inches) horizontally beyond the inside walls of the pool. The 18-inch figure is a common distractor — it applies to other pool clearances. Getting this wrong almost always comes from confusing multiple pool-related dimensions.

Question 3 — Motors and Controls

A motor has a full-load ampere (FLA) rating of 28A. What is the maximum inverse-time circuit breaker size permitted for branch-circuit short-circuit and ground-fault protection?

• A. 40A
• B. 50A
• C. 60A
• D. 70A ✓

Why D is correct: Per NEC Table 430.52 and Section 430.52(C)(1), the maximum rating for an inverse-time circuit breaker protecting a motor branch circuit is 250% of FLA. Here: 28 × 2.50 = 70A. Because 70A is a standard size listed in NEC Section 240.6(A), no rounding to the next standard size is needed. Candidates often select 60A (too low) or miss that 70A is itself a standard size.

How to Read Your Score

The passing threshold is 70% — 63 out of 90 questions. On your first practice attempt, treat your score as a diagnostic snapshot, not a verdict. A first score in the 50s tells you where your gaps are, not that you will fail the real exam.

Use topic-by-topic results deliberately. If you score below 70% in Motors and Controls or Grounding and Bonding — each worth 8 items — those gaps have an outsized effect on your total. A single weak topic in an 8-item section can cost you 3–4 points toward the pass threshold.

Scoring in the 70–75% range on a first practice attempt is encouraging but not a signal to stop studying. Practice questions drawn from a 573+ item pool will surface code sections and calculation types the free exam's smaller pool cannot. Candidates who pass comfortably on exam day typically score consistently above 80% across multiple full timed attempts, not just once.

After each scored attempt, sort your wrong answers by topic. Work that topic in the NEC, then attempt another full exam to test retention. The 270-minute time limit is generous for most candidates, but only if you are not stopping to look up basic definitions mid-exam.

Where Candidates Lose Points

Misreading units in calculations. The Service and Feeders section uses VA, kVA, and amperes interchangeably across questions. Forgetting to divide by 1,000 when converting VA to kVA — or applying a metric prefix incorrectly — drops otherwise correct calculations into wrong-answer territory.

Using the wrong table. Motors and Controls questions live and die by NEC Table 430.52 (protective device percentages) and NEC Table 430.250 (FLA values). Confusing these, or applying Table 310.12 conductor ampacity values without adjustment factors, produces plausible but incorrect answers.

Skipping steps in multi-step problems. Branch Circuits and Conductors and Cables questions frequently require two or three sequential steps: find base ampacity, apply temperature correction, apply bundling adjustment factor. Candidates who stop after step one consistently choose a distractor the question bank is designed to include.

Pooling hazardous location rules. In Special Occupancies, Class I Division 1 and Division 2 requirements differ in critical ways — wiring methods, sealing requirements, and permitted equipment. Treating both divisions as identical costs points on all four Special Occupancies items.

Virginia regulation questions. Standards of Practice, Standards of Conduct, and Renewal and Reinstatement items are sometimes dismissed as "easy." They require precise knowledge of contractor class monetary thresholds and reinstatement deadlines — details that do not appear in the NEC and require separate study.

Running out of specific code recall on Grounding and Bonding. With 8 items dedicated to grounding and bonding, vague familiarity with the topic is not enough. Electrode types, GEC sizing, and bonding jumper identification questions are specific enough that partial knowledge leads to consistent misses.
