An electrical project is estimated to take 120 hours. After 3 weeks of 35 hours each, what percentage of the project is complete?
Answer: 87.5%
3 × 35 = 105 hours; 105 ÷ 120 = 0.875 = 87.5%.
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?
Answer: 86.5 ft
22.5 + 18.75 + 31.25 + 14 = 86.5 ft.
If wire costs $2.35 per foot, how much wire can be purchased for $200, and approximately how many full feet is that?
Answer: 85 feet
$200 ÷ $2.35 ≈ 85.1, so 85 full feet.
A voltage drop calculation shows a 3.5% drop on a 240V circuit. What is the voltage at the load end?
Answer: 231.6 V
240 × 0.035 = 8.4 V drop; 240 − 8.4 = 231.6 V.
A work order lists labor at $85/hr for 14 hours and materials at $620. What is the total job cost?
Answer: $1,810
85 × 14 = $1,190 + $620 = $1,810.
A crew installs 180 light fixtures over 5 days with 3 workers. How many fixtures does each worker install per day on average?
