System grounding is used to stabilize the voltage to ground and reduce overvoltage from contact with a higher voltage line or lightning.
Portable generators meeting 250.34 (A) and (B) don't require connection to a grounding electrode.
Other generators, if a SDS, require a connection to a grounding electrode system.
Why does the code exempt portable generators? (Sorry, this is one of my instructor questions)
