The voltage is applied between live parts connected together and the
accessible parts. If the accessible parts are made of plastic, we need to

It appears the extension sockets are of class 2 and the USB sockets are of
class 2 as well. The product should have double square symbol according to
EN 60950-1. However I have not seen any one have it. Is there something to
