I finished a fourplex four meter pack with four disconnects on one enclosure.And i have four 60Amp feed through one conduit to each subpanel that are installed side by side in a 36"x48" enclosure. I have pulled only one #10 EGC that is being daisy chained from one panel to the next.
I have a feeling that i need four #10EGC.
Am I correct?

Please show NEC reference because i can not find it.

Thank you
Edward

And i have four 60Amp feed through one conduit to each subpanel that are installed side by side in a 36"x48"

what kind of raceway?

One EMT conduit with four "C" conduilets that feed each panel separately. It is not a through feed installation.
I will try to submit picture.

Thanks
Edward

Ed, the EMT itself should qualify as the EGC for each panel. Otherwise, yes, each feeder should have its own EGC, I believe.

One EGC for all the circuits is OK.


Not sure the power company will be happy with the feeders from 4 different meters to all be in the same conduit.

I don't know why the power company would care, since the feeders are all downstream of the main OCP. The AHJ might care, but I don't see any real issues with it.

Power theft would be the power company's issue.

I think 250.24(C) is the section we want.

As I read it, you are only required to have on GEC (wire to a ground rod). The utility neutral, however, must be bonded to the case of each of the disconects- so the egc will terminate to the neutral buss at each disconnect as well.

Reno I believe the GEC would be at the meter stacks with the service disconnect(s) the wires in the EMT are feeders not service conductors.

I agree, Iwire.....I only brought up the GEC as this is the sort of application where things get confused easily. After all, there is the question of what to do with the EGC once it reaches the panel.
