Hi all,

I wish to run 14.8A at 12V DC and have some 0.75mm flex of which is rated at 6A at 230V

Can someone help me out by providing me with the calculation prooving or disproving this flex is ok for the job...I can never seem to remember it with 12V or 24V but can with 230V

Thanks

Is this correct.....

12V x 14.8A = 177.6 Watts

177.7 Watts / 230V = 772mA's ?

So in effect this 0.75 flex rated at around 6A dependant on installation method isnt even drawing a sixth of its potential?

Amps are the heating factor in a wire. Amps are amps, and 6 amp wire is good for 6 amps. It's the insulation that is concerned with voltage.
