It looks like your receptacle (kettle) is grounding at the G bus (upper right). And the G bus is wired directly to the N bus, making both buses up-stream from the GFCI, correct?
Within this panel, how are the G bus and N bus functionally different? Since theyre both up stream from the breaker, and since theyre wired together directly, and since theyre both connected to the three wire supplys ground, what are their separate functions?
If thats remotely accurate, why not just send your receptacle/kettle ground to the N bus, directly next to where your dryer chords ground connects?
within this panel, is the G bus solely intended to ground the spa panel chassis?
Finally, what is the round-and-flat aluminum piece thats screwed to the back of some of the panels Ive seen?
Im sure your box is correct, and big thanks to all you guys, and a sincere apology if this has been discussed ad nauseum. I just want to understand it with perfect clarity before I wire mine up.
