Do you have to put a ground rod for a subpanel?

Although we bond the grounding system, they serve two different purposes. So for your first question: no, it is not against code to install a ground rod at the subpanel. It is actually required by code. Grounding Electrode.

Furthermore, does a subpanel need a ground rod?

Do I need to drive a ground rod and install a grounding bar to subpanel? Yes. ALL sub-panels in detached buildings require at least one, and sometimes two, grounding electrodes, aka ground rods. Whether or not you need two depends upon the soil conditions and the LOCAL code requirements.

Also, how do you ground a subpanel? 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.

Consequently, do I need a ground rod for a shed?

For a single circuit feed to a shed you do not need a ground rod. You do need a separate ground bar for the grounds if you install a panel. If it just goes to switches and receptacles you do not. A 20 amp single pole switch can be the disconnect.

Why do you separate grounds and neutrals in a subpanel?

The neutral wire carries current. So bonding the neutral to the ground in a subpanel will allow current to flow over the ground wire back to the main electrical panel. So bonding the neutral to the ground in a subpanel will allow current to flow over the ground wire back to the main electrical panel.
