How is one volt defined?

maybe yes, things are not as bad as people believe.this regulation was implemented with EU directions, of course. a good thing since people are forced to sanitize their electrical installations. there are also special devices that test portable appliances for insulation resistance and earth conductor continuity.we haven't seen them here yet but they have made these tests mandatory in most developed countries.if Greece is a developed country might be a different kettle of fish. electricians here have needed *always* a license. if you graduate from a trade school you give some exams and you get it.as I am an electrical engineering major I got mine without exams and for an idefinite period of time.

Having a license in electrical and electronics engineering does NOT mean he/she would always be an ethical and responsible person.

SO.... well... :)
