I'm an apprentice in school, just getting a bit confused on which table to go to when trying to understand grounding conductors. So I understand if you have a grounding conductor that goes from the panel grounding bar to the ground rod, this is considered a grounding electrode conductor. But... Lets say you have to size a conductor that goes from your ground bar in your service panel to the metal housing in a 3 phase motor. Wouldn't this fall under a equipment grounding conductor that falls under 250.122? I'm just confused with all this, any help to better understand this would be amazing! Thank you
Edit: Another example I'd also be confused about is a grounding conductor going from your panel ground bar to a ground bar in a pull box. Would that be a bonding jumper, equipment grounding conductor or grounding electrode conductor? Wouldn't that be a bonding jumper...?
