My own power supply is just about finished. Since i live in Europe the voltage here is 230v, from that it goes into my step down transformer that steps down the voltage to around 20 V AC and then into the power supply, etc.
If I check in a normal PC switching power supply the AC ground/earth is connected to the chassis of the power supply. Since i have a wooden chassis for my power supply how do i connect the earth wire to be "safe"? I understand all the risks of working with AC voltages and i try to be as careful as I can. Can I just put some "metal piece" inside of my wooden chassi and connect earth to that?
And just to clarify the AC wire I have contains of 3 wires, One live wire, one ground wire. and one green earth wire. Looks like this:
I have the exact same colors of my wires as the pic.
