What is the primary purpose of GPID in grounding?

• A. To identify and connect proper grounding points consistently and safely.
• B. To describe the color of the wires.
• C. To measure voltage levels.
• D. To list maintenance schedules.

Answer: (A)

Grounding works best when you have a clear, verified set of points that are truly connected to earth. GPID helps by clearly identifying the approved grounding points and ensuring they are bonded together in a consistent, safe way. This makes it quick for technicians to attach equipment or test circuits to the correct ground, reduces the risk of connecting to the wrong point, and helps maintain a reliable, low-resistance earth path. The other tasks—describing wire colors, measuring voltage, or listing maintenance schedules—don’t establish or verify where grounding should occur, which is why GPID focuses on identifying and connecting the proper grounding points consistently and safely.
