It is connected via the EGC connected to the motor, light fixture, heater etc..

Bryan your petard is showing.
If it is an equipotential grid and you are really the bird on the wire, why do you care if you are flowing the next door neighbor's neutral current?
You didn't care when it was the "twinkle lights" duct taped to the handrail and shorted to the 120v phase.
In fact you didn't even want me to operate the branch circuit O/C device. We were just floating safely at 120v above ground.

Personally I want fault current, anywhere near the pool, to flow to the MBJ and open the O/C device.

There is no good reason to knowingly ground the occupant(s) of a pool.


goodnight

I never said any of that. I do care if metal parts become energized by a circuit. However I feel it shoulf be the circuit that energizes the part that clears the fualt, not the pool grid.

I do believe all parts should be bonded together at the pool to eliminate step and touch potentials.

But as soon as grid is connected to the premise grounding system, it becomes apart of normal operatiing current.

I keep telling you that these are different issues, and you keep making them all the same.

Voltage gradients at the pool are to be minimized by the pool equipotential grid. Ground faults should be cleared by EGC's of the supplying circuit. And grounding should be made at the service and only the service and it would be advisable to limit how much normal current will flow through the pool system.

Again, three different issues.

You all keep assuming the equipment that energized the pool will have an EGC. Look around your house and note the number of consumer lighting units, TVs, radios, stereos or other things that might ge dragged out to the pool deck that have a 2 wire cord.
I see that window frame as the most likely place where a non-GFCI might energize the grid. I can see a kid setting their bedroom radio on the window sill and later closing the window on the cord. The same could happen with holiday lighting.
I know the user is doing something potentially hazardous but that is what users do.
Didn't you just write a proposal for CO detectors based on the number of people who run generators in the house?

This is not as much about intentionally bonding the pool to the grid, that already happens. It is about your contention that we should intentionally ISOLATE them. That is virgin territory. Pool equipment has historically made this connection in several ways. I think if/when that connection goes away we will see tombstones.
