Grounding & Bonding Fundamentals (Topic 2) in Module 5 – Solar-PV-NABCEP-Associate (BG)

Grounding & Bonding Fundamentals

Grounding and bonding help reduce shock hazards and improve system safety by providing a low-impedance path for fault current and by keeping conductive parts at the same electrical potential.

Concepts

  • Bonding connects metal parts together so they remain at the same potential.
  • Equipment grounding provides a path for fault current back to the source to help clear faults.

PV systems include metallic racking, module frames, enclosures, and other conductive parts that may require bonding/grounding per code and manufacturer instructions.
