300.3 Conductors.
...
(B) Conductors of the Same Circuit. All conductors of
the same circuit and, where used, the grounded conductor
and all equipment grounding conductors and bonding conductors
shall be contained within the same raceway, auxiliary
gutter, cable tray, cablebus assembly, trench, cable, or
cord, unless otherwise permitted in accordance with
300.3(B)(1) through (B)(4).

i've always thought that running a EGC from a sub to main the EGC was required to be IN the conduit (NMC used) with the feeders...
reading the requirements, i'm not so sure....
thoughts please, i'm having a rather difficult Monday...
thanks... 05 NEC , and it is not at a seperate structure. i did mean non-metallic conduit...should be RNC
i was looking through 300, and i just couldn't isolate the section that stated it...
300.3(B)(3) does not apply to this installation if all the current carrying conductors (and neutral conductor if not a CCC) are run within one raceway....
(3) Nonferrous Wiring Methods. Conductors in wiring methods with a nonmetallic or other nonmagnetic sheath, where run in different raceways, auxiliary gutters, cable trays, trenches, cables, or cords, shall comply with the provisions of 300.20(B). ...
I guess it does say cables and not conductors.300.3(B)(3) does not apply to this installation if all the current carrying conductors (and neutral conductor if not a CCC) are run within one raceway.
...in a very roundabout manner, I might add.I guess it does say cables and not conductors.

I do not believe there is any EBJ in this installation... and many seem to be confused exactly what an EBJ is. The most common example in my mind is a jumper that goes "around" an expansion joint of a metallic wiring method.NEC 352.60 state's that an EGC shall be installed where required. Also, NEC 250.102(E) state's that an equipment bonding jumper can be installed outside a raceway if the length of the jumper does not exceed 6 feet.

Yes but an EBJ is sized the same as an EGC. They both serve the same purpose of providing an effective fault current path.
