Rule #3: In a subpanel, the terminal bar for the equipment ground (commonly known as a ground bus) should be bonded (electrically connected) to the enclosure. The reason for this rule is to provide a path to the service panel and the transformer in case of a ground fault to the subpanel enclosure.
Why do you not ground a SubPanel?

Does a sub panel need a main breaker?
The sub-panel itself does not require a main breaker in it but does require a branch circuit breaker in the main panel it is fed from, sized appropriately for the loads on the sub-panel. That’s why you can find ‘Main Lug’ and ‘Main Breaker’ panels available.
