Hi everyone,
I am struggling with a power supply question. I would like to power up and control 9216 LEDs — strips of 144 LEDs/meter (WWA SK6812 - just like the RGB kind).
These are powered at 5V and draw 43.2 watts per meter at most (when the three leds are lit up)
Right now I have two solutions to solve this but I am not sure if are OK.
My concerns are the following :
- I don't want to risk my life. There will be a lot of current in the cables and I want to know what to expect if I get electrocuted, and therefore equip myself with the right gear to avoid any accident. Or maybe I am just too careful and I misunderstood my old physics courses :).
- I am concerned about cable heating. Which kind of cable should I use for the two different scenarios if one or both are correct?
- Should I need shielded cables to avoid any data corruption because of powering cable passing nearby the data one?
- If the lengths of the cables are to big, could I be seeing voltage drops?
You will find attached the schematics of the two solutions I came up with.
I am really not an expert in this subject and don't want to make any mistakes. I hope it's ok to ask for a question that is probably not that complicated.
If you have a simpler solution for this please feel free to share! 
Cheers!
