EIAT and NEIEP Test EIAT Numerical 5 — Questions and Answers
Question 1: An electrical project is estimated to take 120 hours. After 3 weeks of 35 hours each, what percentage of the project is complete?
- 82.5%
- 85%
- 87.5% (Correct answer)
- 90%
Correct answer: 87.5%
3 × 35 = 105 hours; 105 ÷ 120 = 0.875 = 87.5%.
Question 2: A service panel requires wire runs of 22.5 ft, 18.75 ft, 31.25 ft, and 14 ft. What is the total wire needed?
- 84.5 ft
- 86 ft
- 86.5 ft (Correct answer)
- 88 ft
Correct answer: 86.5 ft
22.5 + 18.75 + 31.25 + 14 = 86.5 ft.
Question 3: If wire costs $2.35 per foot, how much wire can be purchased for $200, and approximately how many full feet is that?
- 83 feet
- 85 feet (Correct answer)
- 87 feet
- 89 feet
Correct answer: 85 feet
$200 ÷ $2.35 ≈ 85.1, so 85 full feet.
Question 4: A voltage drop calculation shows a 3.5% drop on a 240V circuit. What is the voltage at the load end?
- 228.4 V
- 231.6 V (Correct answer)
- 234.8 V
- 237.2 V
Correct answer: 231.6 V
240 × 0.035 = 8.4 V drop; 240 − 8.4 = 231.6 V.
Question 5: A work order lists labor at $85/hr for 14 hours and materials at $620. What is the total job cost?
- $1,800
- $1,810 (Correct answer)
- $1,820
- $1,830
Correct answer: $1,810
85 × 14 = $1,190 + $620 = $1,810.
Question 6: A crew installs 180 light fixtures over 5 days with 3 workers. How many fixtures does each worker install per day on average?
- 10
- 11
- 12 (Correct answer)
- 13
Correct answer: 12
180 ÷ 5 = 36 per day total; 36 ÷ 3 = 12 per worker per day.
Question 7: If 2.2 pounds equals 1 kilogram, how many kilograms does a 55-pound wire spool weigh? (Round to nearest tenth)
- 23.5 kg
- 24.5 kg
- 25.0 kg (Correct answer)
- 25.5 kg
Correct answer: 25.0 kg
55 ÷ 2.2 = 25.0 kg.
