I used this cable to power my Topping D70S DAC. Phase + Neutral are UP-OCC silver, ground is UP-OCC copper. All cables are screened separately by the copper sleeves. Sleeve-ends are connected to the power plug input (ground). With Furutech connectors and you have a ultra high end power cable and it is all save because of fused DAC and no more than ..mA of current dissipation.
