Voltage Drop Question

[pwdrive]

Thanks for the replies everyone, I used 3 decimal places because I guessed millivolts would crop up somewhere, I've noticed that 1mm CSA thin wall vehicle cable is rated twice that of standard PVC vehicle cable in current terms so that must be down to the insulation, I think the breakdown voltage is lower though, 50 to 60 volts seems to be the consensus on the web.
