Quick question about grounding and bonding

[The electron man]

The reason we don't Bond at the sub-panel

Is Because the neutrals can leak voltage to the grounds plus in case of a ground fualt ,we don't want a parallel path back to the source if I'm correct

So at the main panel why aren't we worried that the neutrals will leak voltage to the grounds?

We don't want a compromised neutral to accidentally energize conductive parts expected to be grounded.

So at the main panel why aren't we worried that the neutrals will leak voltage to the grounds?

At the service, the system neutral is the premises zero-voltage reference to which the EGC is connected.

I wouldn't use the word leak, IMO it doesn't apply in this context. The actual problem is the parallel path for the neutral current.

Because in normal, non-fault conditions, you want zero current flow in the grounding conductors. That way they won't have a potential difference to grounded objects, they're always safe to touch, and safe to bond conductive items to.
