Grounding (Electrical)
Connecting electrical equipment to the earth to provide a safe path for fault current, preventing electric shock and allowing protective devices to operate correctly.
Why It Matters
Proper grounding is a code requirement for solar systems. Missing or corroded ground connections are a common inspection failure and safety hazard.
