Jerry,
Does the grounding conductor have to be installed seperatly from the nuetral bus? If you notice, they (green/white) are both in the grounded bus.
The lower pic is the grounding bus.

Here are a couple of drawing I did. I suppose my question is; if the main has seperate busses, then does the pool panel have to seperate where they place their grounds in the main? Or does it even matter?

Also, if you notice the the first picture the two grounds are placed in the bottom nuetral bus and NOT in the upper grounding bus. This is correct?

Hi Markus,

Yes, the neutral conductors need to be isolated from the grounding conductors in any panel down stream from the service equipment panel.

In your drawings, the panel marked "Main" (which, by the way, you do realize means nothing, right?) is, I am presuming, the "Service Equipment" (which means a lot), and, *IF* such is the case, the neutrals and grounds in the "Service Equipment" are allowed to either be on one terminal bar or on separate terminal bars which are bonded together.

The pool panel feeders will effectively start out at the "service equipment" with the ground and neutral bonded together (either on the same terminal bar or by having separate terminal bars bonded together), however, as soon as those feeders leave the service equipment enclosure, the ground and neutral is no longer allowed to touch, come in contact with each other, or be bonded together - the neutral is required to be kept isolated from ground as soon as it leaves the service equipment enclosure.

Also, if you notice the the first picture the two grounds are placed in the bottom nuetral bus and NOT in the upper grounding bus. This is correct?

As long as that is service equipment it would not matter as the ground terminal bar would be required to be bonded to the neutral terminal bar anyway.

Now, if that enclosure you are calling the "Main" IS NOT the "service equipment", then the above information will change.

My mistake, I did mean to say SEP.
Okay, your answer is what i figured. I shouldnt doubt myself but it's sometimes difficult when you read things on "other" forums.
Thanks for your time.
