Bonding comes into play when there is metal spread all around. Each piece of metal can "built up" ( for lack of a better word ) a small electrical charge. Now you have " power plants" all over the place. Each are on its own and between any two you can get a buzz. Can be a tingle, can be enough to knock you socks off. So in order to stop this ,,,,, ALL metal, not just for pools, HAVE to be on the same potential. That means wiring them together. metal studs in your home, tracks in ceiling tiles etc , all should be tied together. Steel / metal is not put around pools to be a bond, the fact it was put there for some reason causes it now to be tied to all other metal in the area.
Running a wire to the items on your pad stops any one of them from getting out of line and building up a current that is not the same as the others. You Can Not get a shock from touching within "arms reach" any two items that are on the same potential IF you are also on that same potential.
The problem with grounding ( we are off the bond thing for now ) is that a ground rod driven into the ground right there, and then another over there can be and more then likely will have a current difference between them. Ground is NOT ground. Rod materials, soil type, etc all puts them at different levels of ground. This is why we should have only one ground rod in our electrical. You will notice in a Main power box there is Bond screw, and on any Sub Panels you SHOULD see that bond screw is missing. Missing around with that has changed over the years by the experts and even now some places have it one way and others the other way.
