Where I am you would have no obligation with this at all. You did a service upgrade. End of story. The inspector can tell you whatever he wants done elsewhere in the house but you don't have any obligation to do it. It is up to him to notify the property owner in writing if he has a problem with something. At this point the homeowner can have the problems repaired. I have had inspectors come through a basement on a service upgrade barking out commands like he's General Patton, "Unplug that cord, staple that bx, put a cover on that receptacle," etc. I usually just nod and say I'll pass the info on tho the homeowner. With all that said this does sound like a hazard that should be addressed by someone.
