Sub-panel feeders

I am being told I need an insulated ground feeding my sub-panel which feeds a pool panel. I have an insulated ground from the sub-panel to my pool panel. Why am I being told the sub-panel needs one? Code states:

680.25 (B) Grounding:

An equipment grounding conductor shall be installed with the feeder conductors between the grounding terminal of the pool equipment panelboard (which in my case is the pool panel) and the grounding terminal of the applicable service equipment (which in my case is the sub-panel) or source of a separately derived system?.this equipment grounding conductor shall be insulated.

Any thoughts?
 
As far as I know you do not need an insulated EGC for your sub-panel.

Did you ask the person for a code reference?

I do not see how your sub panel can be the service equipment.
If it is neither the service disconnect nor the first OCPD of an SDS, it looks like the insulated EGC has to keep going back until it arrives at one or the other.

PS: Even if your sub panel is listed for use as service equipment, it is not the service panel unless the service neutral comes into it and the ground to neutral bond is located there or immediately ahead of that point as allowed by code.

Insulated ground needs to be used for the pool. The 2014 changed the ruling a bit.

680.25(B) Grounding. An equipment grounding conductor shall be
installed with the feeder conductors between the grounding
terminal of the pool equipment panelboard and the grounding
terminal of the applicable service equipment or source of a
separately derived system. For other than feeders to separate
buildings that do not utilize an insulated equipment grounding
conductor in accordance with 680.25(B)(2), this equipment
grounding conductor shall be insulated.

Do you think that the requirement to run the insulated ground to the service equipment means that it must remain isolated as it passes through sub panels? Or can the insulated ground wire in the sub panel feeder be in parallel with the raceway EGC or uninsulated EGC that originally served the sub panel?

I guess I never install pools thru sub panels so I hadn't thought about it but IMO, as long as it is insulated I don't think it matters.
 
So, I guess the OP either needs to get his pool feeder from the service panel with an insulated EGC or if the feeder does originate from a sub panel then the insulated EGC has to go back to the service panel?

That is the way I read it.
With either Dennis's interpretation or my stricter interpretation of what can happen to that wire in the sub panel.

If the pool panel is being fed from an EXISTING sub-panel with a equipment grounding conductor within the sheath would the Exception to 680.25(A)(1) not cover this?

Nicely done!

The OP did not quote the full text of (B), especially the part
For other than (1) existing feeders covered in 680.25(A), exception,....the grounding conductor shall be insulated.

But that exception in turn only applies if the existing feeder uses flexible metal conduit or a cable assembly. If it is wired in non-flexible conduit, such as rigid or EMT, and uses the raceway as EGC or includes a bare EGC, the the exception does not help the OP.
So we can hope, on the OP's behalf, that the feeder to the sub panel is NM or similar.

I'm not positive, but some jurisdictions require an exterior device to disconnect power; others allow conductors (both before and after the meter) to enter the structure and have the service disconnect indoors. This is commonly for fire departments to kill power. I'm guessing that is his usage.
