In hifi electronics, CD players, Cassette Decks, Turntables and integrated amps come with power cables as hard wired from the inside. On the both sides of the moulded 2 pin plugs, there are many standard universal logos for the different information of the specification. I want to know from that all those specification: How to identify the pin of 'Phase' and the pin of 'Neutral?. Please share your ideas. Thank you.
