I have been remodeling a 2 family home into a single family home which
had 2 main panels. I would like to make one panel into a subpanel but
am not sure how the grounding should be on the subpanel. Can I leave it
ground the way it is (as a main panel) or should it be ground to the
other main panel now? Any help would be greatly appreciated.

As a sub panel, it will get its feed from the main panel. The feed will be
four wires, two hot, one neutral, and one ground. In the sub panel there
will be a neutral buss and a ground buss, which are isolated from each
other. The neutral loads will be attached to the new neutral buss, and the
grounds to the ground buss. Be sure to remove the bonding jumper which
currently connects the neutral/ground buss to the panel

If you have to ask this, I sure wouldn't want to live in a house with your
wiring. Good luck with the inspector.
