How can you be sure of this person's intention? And whether they did indeed know what they were doing? Im just asking because its just one photo of a green wire clamped to copper piping. How can you be sure what the installer understood based off this one photo?
Not trying to stir the pot, just trying to understand the line of thinking here. You may be 100% correct i just wanna learn more about bonding and grounding because its something that i dont fully understand yet
