From the story: "They claim the contractor knew that hazardous conditions existed from improper grounding of faulty electrical systems manufactured in China for sale only to countries outside the United States because they did not comply with U.S. electrical safety standards."
I sure the generator is simply a copy of what can be obtained anywhere else. There's no details about the electrical safety standards the gen did not meet mentioned. I'm sure they're irrelevant though and amount to not meeting UL stds. There is nothing that could have possibly have existed in the gen engineering that would have caused an electrocution if it was properly wired and interfaced with a proper distribution panel. THe safety stds were in regard to the propensity to fail, or maybe spit fire and sparks during a failure.
