Since I see We are on a Pool type train of thought and it does somehow make me feel warmer Let me try a question of my own.
We know (right?) that the pool itself and associated equipment need to be bonded together but it is not required to be connected to the equipment grounding conductor of the service or circuit supplying power. My question(s) is which way is best and does that change depending on location? Inside, outside, or other factors. In other words, if it was just as easy to do it either way, which would be preferrable?and why?
That would be my guess, but there might be a downside to it I don't know about. The pump would already be bonded to Equipment ground through the grounding screw inside. Is another connection advantageous? I used to connect bond wire to the #12 insulated ground near the pump location. Suppose the connection was elsewhere, or if the Bond wire was connected directly to the panelboard? That would mean Parallel paths with different resistances. What about Lightning? Is it good to have a low resistance path back to the Buiilding?
Does anyone know if any of these are legitimate concerns?

I can see where someone replaced a pump and did not connect the ground wire, or wire was loose, lost that little green screw, broke the Ground prong off etc. These things happen all the time to other types of equipment.
