Thank you! What about when there's only one MOV between hot and neutral instead of a group of three, how does it pass that spike to ground? Or does it just pass it to neutral?

Neutral is there specifically to handle small surges. Especially in wye configurations and neutral eventually goes to ground. Having it connected to both neutral and ground is a fail safe. No neutral goes to ground, surge too high for neutral goes to both or some large f-up voltage spike from neutral goes to local ground.
