My first time wiring an inground pool. Any site that summarizes this ? I have seen an equipotential drawing. Thank you.

I've done lots of pools and will answer questions, but it would be hard to just list everything as situations are different.
I will say one thing, to make sure you coordinate with the contractor or installer, not to do any concrete pouring, paver laying, etc. until you get your bonding grid in and inspected.
 
I've read these, thank you. It turns out the pool person says he does the bonding and requesting inspection before pouring concrete. I read that all metal fixtures are bonded together (like ladders, etc) with #8 Cu, which he says he uses. But my question is once all metal parts are bonded together (including he says, a line buried around the pool), do you connect this conductor to anything else (like a ground rod) or is the goal to just bond all the parts together ? I know it's a stupid question, bonding is not grounding, but...

This is just bonding all the metallic paths around the pool to create the equipotential bond. Nothing goes back to the panel or a ground rod. Now, the system grounding system will, by default, get connected via the pump motors or other equipment that requires an EGC and bonding to the pool bond. On the same token, if there happens to be no equipment for the pool (very rare), and the pool was nonconductive, you would still have to install an equipotential bond if nothing but the perimeter ring/grid and pool water is involved.


ETA: The "pool person" should run a tail from the perimeter ring to the area where the pool equipment is. It would then be the responsibility of the electrician, or other qualified installer, to connect the equipment to this tail. IOW, take the tail to the equipment's bonding lugs.

They will run that bonding wire to the equipment pad. You will connect to the external bonding lugs on the pumps. If you have a chlorine generator, the transformer enclosure will have a bonding lug also. If it’s built into the control panel, you’ll see a lug on the bottom of that panel. Gas fired heaters and heat pumps also get bonded.

The pool installers usually know this, but make sure your 4 points of connection to steel are between 18" and 24" from the inside wall of of the shell. I had an inspector once turn me down because I did not make the connection, the pool installer did. It was really petty I know. But technically, he was right. They are not licensed to do electrical work. Also, any 1" PVC conduits that they run for lighting, make sure there is not more than 360
degrees in bends. I haven't seen any wet niche fixtures in pools in many years, but if you do have one, a #8 solid is needed to bond the shell of the wet niche fixture also.
