Hello everyone first let me start by saying I am new to electronics so if my explanation seems a bit off please forgive me. So basically I wanted to create my own 24volt power supply for bread boarding projects. I found two old identical power supplies I had that were rated at 12v 2a.
I then googled a circuit that showed how to wire them in series here

*NOTE my power supplies are not grounded (plastic case)
Now everything works great, but I'm having trouble wrapping my head around the concept. How exactly does the neutral of power supply two handle the increased voltage? Lastly, is this method safe?
