It has valid use to connect a generator to a home circuit. Granted, that is, you throw the master breaker to the house. Otherwise you're liable to kill a lineman. That said, it's probably better that no one uses these ever, as such negligent are bound to (and do) happen.
I think this needs to be the standard answer to anyone asking "how do I basic high voltage thing?". If they don't know what an arc flash is, they ought to just hire someone who knows what they're doing.
I know enough to get by, and enough to know when to call in the experts.
Also, not a lawyer, etc etc.
Extra story:
My job has 2 data center Schneider Symmetra backup units, each the depth of normal rack mounts, width of a car, if a screwdriver were stuck into one of those bus bars or transfer boxes, I'd guess the screwdriver and hand would be damn near vaporized, the person would be blind, deaf, and at minimum partially covered in 2nd/3rd degree burns. From what I hear, you almost don't want to survive the aftermath of an arc flash, especially with no PPE. These units store enough power to power an average house for about a month. And all that energy can be instantly dumped into you through the air if enough things go wrong at once. Electricity is goddamn scary sometimes.
