I beg to differ.
Your response was in reference to the example mtnelec posted, which was an example of improper wiring causing neutral current to flow on normally non current carrying parts of an electrical system from the neutral conductor being attached to the metal pole.
That's different than a fault.
No amount of grounding or bonding would clear that neutral return current flow beacause its not a short, it's simply a parallel return path.
Nothing short of a GFI protected circuit to the pole light that is.
If we wanted to exaggerate the issue of a fence becoming energized due to an actual fault, without proper bonding and grounding throughout the system,we could " electrify" a metal building of any size and never clear the fault.
