I am just now finding your thread. What an adventure it has been. So if the bond was cut/broken then that means it has been going on for a while. I can't wait to see what happens when they lay the new grid!
True question-How do you test for the voltage showing up in the water? Is the only way to get in and feel in on your skin?
That’s a great question! We only found out when our kids and their cousins complained of the water stinging them one afternoon.
After a lot of research, I found that yes, basically there is stray voltage most everywhere, but that’s why the equipotential bonding grid is so important, in order to keep all voltage the same around the pool and tied to a ground. They will test the continuity to ensure all conductive surfaces, including the water and the deck are all tied together to keep all voltage equal, because only when there are different voltage potentials between conductive surfaces, is when the electricity jumps and causes a shock.
The hardest part is that the pool didn’t always “sting” (it’s not a constant we can measure against), so really all we can do is ask a lot of questions and trust the pool electrician is doing it correctly, and get it inspected afterwards. I’ve read the whole national code for Equipotential Bonding Grid installation, and will be very forward with my expectations.
The deck is going to be beautiful, but we’re only doing it to make the pool safe. This is the most important part of the project, and I’d be lying if I said that I wasn’t nervous, and a little out of my depth.
