Default Another subpanel grounding question

Hey all-

First off, I apologize for asking a question that seems to be asked
a lot around here. I've been reading posts on the subject for about 2
hrs this morning, but I'm missing something.

My situation: I have a main panel in my house, and I have an
attached garage which my dad and I put a 60amp subpanel in. Now I
know that I need to keep the neutral and ground separate in this
subpanel (I've seen LOTS on this topic), but what I'm missing is,
where do I connect the grounding bar in the subpanel? Grounding rod,
ground wire back to the main panel, don't need it?


ground bars are attached to the can of the panel in the provided holes. The
neutral bar must be isolated from the can. Get a ground bar/insulated
neutral kit for the panel you bought.
You need to carry a code gauge ground wire from the service to the subpanel.
Driving an ground rod at the subpanel is allowed and is called a
supplemental ground. It must have a ground wire as large as the service has.
If you drive a ground rod and do not have a ground wire properly installed
you have created a ground loop. Not a good safe way to use electricity. But
then again there are a lot of people that choose this method.
