Technically proper for the theory behind “bonding.”
The main purpose of “bonding” is not to direct stray voltage (that is the purpose of “grounding”), but rather, bonding is intended to eliminate the potential for transfer of current between components. A proper bond will also include a solid grounding connection that will produce a fault large enough that it will open/trip the OCPD of the circuit, in the event that there is “stray” voltage.
Think about it this way (I know you understand this David, but many are still confused about the principles of bonding);
When you rub your feet on the carpet and touch a door knob, you get a static shock. That is the transfer of current, which bonding will prevent. If you are holding the door knob (“bonded” to the door knob) and you rub your feet, you will not get that shock if you touch the door knob with the other hand.
That’s because you and the door knob share the same electrical potential (potential to ground). The static build-up is the same within your body as it is with the door knob while you are “bonded” to it.
Now if someone else comes along and touches you or the door knob, they will receive the charge (shock) that is being stored from when you were rubbing your feet on the carpet (i.e. “stray” voltage). That’s why the grounding connection is important.
The grounding connection will take that charge to “earth.” In the case of an electrical circuit, it will open/trip the breaker.
