Newer SD 200 amp main service panel. Most of the grounded & grounding conductors were installed appropriately on the bus bars. However there were two isolated (bonded to panel) bus bars on both sides, with a few grounded & grounding conductors installed there. Now, I know the grounds are o.k. here, but what about the neutral wires and/or grounded conductors? Do the neutral wires need to be installed at the main neutral bus bar(s)?
Thanks in advance.
