EqGrCond in meatllic conduit

Does he really need to pull it out or can he just disconnect the egc? I see no issue with leaving the wire in the conduit and disconnecting it.

Feeders in parallel require a full size EGC in each raceway. This has been a common mistake by designers and installers.
I believe the reason is a fault can be feed from each end.

Very common mistake and I would agree that the available fault current is in each pipe.
 
How about 310.4(C) raceways shall have the same number of conductors. What is it then?

If it is not connected to anything then it is not a conductor...:smile:

250.118 describes EGCs and not one part of it says it has to be connected to anything. :D

But did you read 310.4(C)?

It requires that the raceways have the same characteristics, having one raceway having one more EGC or 'not-conductor' then the others is a violation.

I guess the reason I a take a hard line here is this is the kind of work I do all the time and I follow the rules, I see no reason to let someone else break the rules just because they took on work beyond their knowledge.
 
I did read the art. and I am only half serious here. I can see the egc taking up space and perhaps causing more heat - or less heat dissipation then the other conduits.
 
shouldnt there be a 1/0 gec in each conduit, or if you can use the conduits as the grounding means, how do you calculate the conduits for for effective ground fault path, or can you. Any info would be appreciated thanks.
