Why Other Answers Are Wrong

Option A: Incorrect. Ground system shouldn't be as close to station equipment as possible - it should be outside the building. Close to equipment is wrong. Option C: Incorrect. Ground system shouldn't be next to closest power pole - it should be outside the building, not necessarily near power pole. Power pole location is wrong. Option D: Incorrect. Ground system shouldn't be parallel to water supply line - it should be outside the building. Water supply line is wrong.

Exam Tip

Lightning protection ground = outside the building. Think 'L'ightning 'G'round = 'L'ocated 'G'rounding outside. Lightning protection grounds must be outside to properly dissipate lightning energy to earth. Not close to equipment, not near power pole, not parallel to water - just outside building.

Memory Aid

Real-World Example

A station's lightning protection ground system: Ground rods and conductors must be located outside the building to properly dissipate lightning energy to earth. If the ground system is inside, lightning energy could enter the building, causing damage or injury. Outside location is critical for lightning safety. This is where lightning protection grounds should be located.
