For instant digital access to get the job done right, NFPA LiNK® is your window to productivity.
Learn how to quickly find the information and answers you need with seamless search and navigation.
In this video, we’ll look at the equipotential bonding requirements for permanently installed swimming pools based on Article 680 of NFPA 70®, National Electrical Code® (NEC®), 2020 edition.
Equipotential bonding is used to reduce voltage gradients in the pool area. The exclusive enhanced content in NFPA LiNK will expand upon the code text for more detail. Illustrations of swimming pool equipotential bonding connections within NFPA DiRECT® provide easy-to-understand visual aids of the NEC-required connections.

I'm so glad this was on my radar because I am an NFPA Link subscriber and I had no idea about the NFPA Direct section of the site. I've been really impressed with Link membership because I can navigate the code in the field without putting on my glasses and thumbing through the code book. Also, I really appreciate the free Link socks I got at the IEC Dallas Convention. Frigging awesome!

Do I need just bonding all the devices metal machine etc “ close the circle ⭕️ between them and No add to any Rods or panel ground ??

You don't need any rods or anything. This is a good simplified explanation: kzfaq.info/get/bejne/itmGes-mt7vFh58.htmlsi=pWShY6BtLgXrOQZu

The voltage gradient that equipotential bonding addresses arises because electric utilities use the the earth as the return path BETWEEN MULTIGROUNDED NEUTRALS EVERY ⅛ MILE for current to the generation source BUT POOLS, PONDS, OTHER WATER BODIES between those multigrounded neutral points HAVE LOWER IMPEDANCE THAN THROUGH THE EARTH, so a voltage gradient (a step or reach voltage difference) results.
