Any electrical device -- an appliance, an extension cord, whatever -- must be able to tell the power outlet, "Hey, power outlet, I'm drawing too much current. Shut me off now, before I start a fire."
Orice dispozitiv electric, un aparat, un prelungitor, orice, trebuie sa fie capabil sa spuna prizei, "Hei, priza, folosesc prea mult curent. Inchide-ma, inainte sa provoc in incendiu."
