Correct answer to question 9041
- A: Indoor livestock confinement areas with concrete floors where metallic equipment is accessible to livestock
Explanation
Equipotential planes are required in livestock confinement areas with concrete floors that contain metallic equipment accessible to animals and likely to become energized. Livestock are very sensitive to small voltage differences, so the plane keeps floor and equipment at the same potential.
