Hey guys
Long story short I'm building an arcade stick to work on actual arcade hardware. 4 directions, 8 buttons, ground and VCC +5v; so I need a cable with 14 cores minimum.
Obviously a 14 core cable is going to be pretty thick and rigid, so I'm going for unshielded with as thin cores as I can get away with. I've seen some cables 4.5-6mm diameter which is typically thinner than Cat5 which would be perfect. This cable will be the cable running from the controller to the console/arcade board so it can't be too thick.
The thing is that the cables I have found are rated at 250ma and I do not know the current draw of the device, but I do know it's less than 500ma as it is able to be powered by a standard USB socket.

The arcade stick itself will need to power 4 control PCBs and LEDs for 6 buttons (I believe the LED inserts I have ordered are 2x surface mount RGB LEDs per button, so 12 in total)
The 250ma cable is 7x0.1mm strands (I believe 30AWG). Now I've also found some 7x0.127mm (28AWG) cables, but they do not specify the max current.
I believe there is a way to calculate the current handling of a cable, but I've looked around and found conflicting information.
Can anyone kindly give me an estimate as to how much current a single conductor in a 15 core, 7x0.127 cable can handle? Much thanks.
If anyone knows where to buy 15 core cable that can handle 0.5a through one or two of the conductors, I would really appreciate it. I'm having trouble finding what I need.
