He does a good job of outlining the bonded/not bonded and ground rod vs. no ground rod NEC requirements pretty clearly. I do quibble a bit with his implication that in a properly set up system that fault=breaker trip. As long as one doesn't overcurrent a fault won't trip a breaker, now a GFCI may provide that protection.
One thing he does do well is tie into NEC code requirements, especially the requirement that a home system have ONLY one ground/neutral bond and the difference between bonded and unbonded generators.
BTW I do have a transfer swith for our house in case power goes out, and configured for unbonded generators.
