My First DIY Power Cable

@mbolek

Take a look at the link I posted earlier. The math doesn’t work on the cable gauge and, if each wire is the same gauge then the ground with only 4 wires is smaller than the hot and neutral which each have 6 wires. If the posted wire size area is in fact 0.5813mm² then the following sizes would be accurate:

• hot and neutral - 6x 0.5813mm² = 3.49mm² = 12 awg
• ground - 4x 0.5813mm² (19.5AWG) = 2.32mm² = 13.5 awg

The good news is that 12 awg would be a better size for most power cords compared to 19 awg.

Never said the cable was 19awg.  L/N are ~12awg, G ~13.5.  Pretty adequate for a PC.

@mbolek - One thing to note about this cable

if the cable is used with a balanced power supply or used in counties like Norway where the power grid is balanced

• i.e. the live and neutral both carry the same voltage just 180 degrees out of phase
• then the outer wires MUST be used for Neutral and Live conductors for the components to sound it’s best

If the cable is used on a system that uses a more conventional approach

• i.e. where the neutral is connected to the ground at the breaker box
• then the central conductors CAN be used for the LIVE conductor
  • it should sound better - lower noise floor - better image

It will be very interesting to hear your observations

Got a cable , connectors and a little shrink tubing.  Any recommendations on sheathing?  Didnt want to buy a 100 foot role on Amazon.

@jbuhl

bunch of options....
