Hello
I'm in Australia, so my mains is 240VAC 15A. It has 3 holes for the plug (but some appliances only use two of them)
My question is, what are these leads? I know the top two are power and the bottom is earth, or ground but what does this mean?
Is the top 2 "negative and positive" obviously its AC so its changing but thats where there is power. And i hear people calling these wires "live", "hot" whats does this all mean.
- What are all the wires called, and where do they go.
- What are they used for?
- And this originally lead me to this curiosity, the earth lead. there is NO power in there right? it is only earthing the appliance used yea? Why does the appliance need to be grounded. and i saw a guy connect a wrist band into this ground plug on his wall outlet, my first reaction was WTF you idiot!!!! but im not sure how it works.
Very simple question, hope you can help bro
