Hello,
I opened up an AC to DC power supply today to see where they connected the Earth ground wire and I found that it's connected to the negative side (labeled V-) of the DC output. V- is also connected to one side of the transformer's output. Why would they connect the Earth ground wire in this way?
Thanks
