My portable generator pulls double duty as a home backup and is also occasionally used on the job, so I always just leave the neutral bonded to the frame.
Doesn’t OSHA require a generator used on a jobsite to have the neutral bonded to the frame?
Maybe manufacturers could put a switch on their portable generators to change the configuration, instead of having to manually remove and install a jumper wire. Then again, that might just make things more confusing.
IMO, no matter what perceived hazard exits because of this situation, from a safety standpoint, things are still light-years ahead of where they were 10-years ago.
It’s got to be much safer than backfeeding into a dryer receptacle, like so many people used to do before all these home transfer switches and generator-ready load centers became readily available.
