The video dissects a USB-C cable marked with a 10A rating even though there is no such rating in the standard.
It would be interesting what this is meant for, as I’ve never seen a device with such a rating?
48V, 10A at 6 feet or less length requires 16awg wire for <=3% loss (which is the critical appliance standard rather than the more lax <= 10% used for most DC circuits). That’s a wire with a conductor diameter of 1.3mm ~= 0.05in.
The cable probably isn’t 10A rated. But, it’s not an overly thick wire to get it done. Most of the girth is insulation and shielding.
This is overly simplified. And, I didn’t care to watch the video.
