Pool Bonding and Grounding.

One of your illistrations shows the connections, but it is not really clear.

The code says 12AWG ground to the motor circuit, and 8AWG for the EPB.

My question is not that they must be connected, but where to connect them.

At the Motor casing?
At the motor outlet?
At the house?

How far back to take the #8?

If I only went to the motor housing, then suppose they used a double insolated motor?

If I have the motor circuit coming from the house to the motor in PVC with PVC outlet boxes for the switch and outlet should I drill a hole in the bottom for the #8?

An update to the NEC should make this more clear....

Thanks.... Jeff

The #8 EPB conductor(s) do not have to go to the service or into anything other than specified in 680.26. The #8 simply connects to the external ground lug on the pump motor.
In the case of a double insulated pump motor see 680.26(B)(6)(a).

Keep in mind you are addressing two different issues.. bonding and grounding.
The #8 is used for equipotential bonding. By virtue of it being connected to grounded equipment it is "grounded", but the #8 is there to BOND pumps, lights, perimeter surfaces. pool frames or shell, etc. together. It has no intentional connection for grounding.
