My First DIY Power Cable

@mitch2 - thanks for that clarity.

A very interesting design.

In some ways similar to the Helix DIY cables

• Helix DIY power cable

Based on the effectiveness of my Helix DIY power cables I would actually use

• the center conductor as the LIVE
• and the outer wires for ground and neutral,
• which would have a "screening" effect around the center (live conductor),
  • while minimizing induced noise from the center conductor into both neutral and ground conductors
    • i.e. assuming those outer wires are infact spiralled around the center condcutor.
• plus another benefit of the DIY Helix cables is the ground and neutral is larger than the Live conductor - which is also the case if this approach is adopted

Just thinking out loud 🤔

Hi Steve,

As you posted...

Red - line 

Black - neutral

Yellow - ground

Although, each wire/conductor is 19.5 AWG.  

This is very solid cable.  Prices have actually dipped below $100 at times...

Steve,

May have to try swapping the the yellow/red as you point out. I have two cables so could be an interesting eval...

Plus they are terminated with fork terminals for easy/secure connections.

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.
