Need some help getting my head around 680.26 (B) Bonded Parts:
Membership Pool has grid and all metal parts bonded and and fed to a bonding bar in equipment room.
At the bonding bar is a 3/4" ground rod driven and bonded to the bar. The bonding bar is not provided with a connection or bond to anything else (other than the direct earth) to provide a path back to the service to clear potential faults. Isnt a low impedance path back to the source crucial and/or required to efficiently clear faults?
680.26 (B) states in last part "Connections to bonded parts shall be made in accordance with 250.8. An 8 awg or larger solid copper bonding conductor provided to reduce voltage gradients in the pool area shall not be required to be extended or attached to remote panelboards, service equipment, or electrodes."
