I have this 120VAC to 5VDC transformer
I am planning on using 3-wire 14AWG to carry 240V
So you are going to use 240VAC to power the AC-DC POWER SUPPLY?
I have this 120VAC to 5VDC transformer on my pcb http://www.cui.com/product/resource/vsk-s10-series.pdfI use the +5V side to power my project. Do I have to keep the -5V side separate from earth ground? Also, in the schematic in the datasheet, there is a part that should be tied into chassis ground. Can this just go to earth ground?Thanks in advance!
That power supply has 100uA leakage current, so you'd be best to ground the 0V output otherwise it'llfloat at some sizable fraction of mains ac voltage.
Is not -5VDC but rather 0VDC or GND.Tying that ground to earth is fine in my opinion.
I'd be thinking of how I was isolating that second hot wire actually, it's still an exposed core within the cable.
I am going to use one hot leg (120V) and was planning to use the earth ground as opposed to bringing in a neutral as well since the earth ground and neutral are usually connected at the panel anyway.
