Going to be running power out to a new above ground pool. One circuit will be 20a locking gfci for the filter and I also have to add a second gfci 10′-20′ feet from pool as a convenience outlet. I’m going to seperate them into 2 seperate circuits in pvc conduit. I’m going to run 10 ga. for the pool filter b/c it’s about a 150′ run and 12 ga. for the second outlet. My question is to conserve on conduit space, time and copper can I run both circuits off one 10 ga grounding wire or should I just run a second 12ga. grounding wire for the second gfci outlet. I can’t find any info on this in my code books.
Much appreciated, Chuck

Two ckts in one conduit to the filter, then continue the 12ga ckt to the convenience outlet?
10/2 w/G and 12/2 to the filter, then 12/2 w/G to the outlet?

correct, SamT
Ok, consider this another bump so someone who knows better might jump in with the answer.SamT
Yes, you only need on EGC sized to the size of the largest branch circuit wire, #10 in this case.
But there are a lot of very specialized requirements for pools.
I sugest that you look at this.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
Bill,
That's a pretty good link. I hope he's willing to update it, at least when the '08 code comes out.
Only thing I didn't like was his lack of use of expansion couplings in the photos where rigid PVC comes out of the ground into fixed boxes. Maybe he lives in an area where ground movement is not a problem, but he should at least mention it.

The one #10 ground will work. It needs to be insulated and green, with one very specific exception relating to a double-insulated motor.
