APPENDIX Ⅳ THE RELATIONSHIP BETWEEN THE 12V
DC CABLE DIAMETER AND THE TRANSMISSION
DISTANCE
It is the recommended transmission distance when the cable diameter is fixed and the 12V DC
power consumption is below 10%. For the DC device, the max permission voltage power
consumption is 10%. The cables used in the following sheet are all copper wires. (the resistivity
of copper is
