Do you need a bonding grid around a hot tub?

...
This is why the EPBG is not required to run back to the service panel, and can even be isolated from it in the case of a double insulate pump motor if that is the only electrical equipment the pools has. any fault current should only flow back on the EGC's or line to neutral where it should open a breaker or GFCI device. ...

Wayne,
No it can't be isolated from the electrical system, even in that case.

680.26(B)(6)(a) Double-Insulated Water Pump Motors. Where a double-insulated water pump motor is installed under the provisions of this rule, a solid 8 AWG copper conductor of sufficient length to make a bonding connection to a replacement motor shall be extended from the bonding grid to an accessible point in the vicinity of the pool pump motor. Where there is no connection between the swimming pool bonding grid and the equipment grounding system for the premises, this bonding conductor shall be connected to the equipment grounding conductor of the motor circuit.

According to DOI in the state of NC, a bond grid is even required to be run for a hot tub on a wooden deck. We are required to meet the requirements of 2008 NEC with the # 8 copper following the shape of hot tub in earth below deck. I am an inspector and don't see point on wooden deck well off grade but must follow code.
