So we could attach an open wires to the case and everything sould be ok, eh? I'm not gonna try it, heh.

Never thought about that. Atctually, this works in cars, too. If the car gets struck by lightening or severed power line, anyone is safe untill they leave the car. And the car has many windows. Never, Never, exit your car if a power line falls on it.
