Equipment Grounding
- PV panels should follow electrical grounding conductor sizes - [1]
- Ie, for 30A DC, we need 10 ga ground.
- PV frames must be connected to PV system equipment grounding conductor [2]
What Size Grounding Conductor on PV Panels?
- Australia rules - appear to say 6 ga for lightning protection, and 12 ga for frame grounding [3]
- 6 ga USA if 'subject to damage'?
