I'm with you, Pierre!
I think 300.3(B) is self-explanatory and everyone can agree on that.
Now, 300.3(B)(2) gives us an "out" for the bonding conductor. "Equipment Bonding Jumpers shall be permitted to be installed on the outside of raceways in accordance with 250.102(E)."
Okay, I understand that some of you are saying that the bonding jumper isn't inside of the "service raceways", meaning the 2 PVCs that contain the service entrance conductors. That is certainly one way to look at it.
So then there is the restriction to six feet when outside of a raceway from 250.102(E). But y'all are saying that we can negate the 6 foot rule by installing the bonding jumper in its own raceway. Well and good.
However, I just don't agree that is what it says. By the exact reading of the code, if a conductor is "outside of raceways" then a conductor that is inside of a raceway is not "outside of raceways". I do not think that 300.3(B)(2) is implicitly referring to only the raceways containing the circuit conductors. To me, "outside of raceways" means absolutely positively not in a raceway. It doesn't say "outside of THE raceway", it says outside of A raceway.
If a conductor is outside of a raceway, and then you put it in a raceway, it is no longer outside of a raceway, so it can't be installed outside of a raceway by the rule in 250.102. Man, this is too fun. :smile:
In this installation, the phase wires, the grounded conductor, and the bonding jumper are all components of the same circuit according to 300.3(B). And as such, we have THREE parallel conduits which contain portions of the parallel service entrance. And, each of these three conduits must meet the parallel conductor rules. You can't have phases in some and no phases in the other.
This is good stuff.:smile: I hope we can get some more good debate.
