Aluminium cable amperage not enforced

Hello,

It seems that aluminium cables (1x) can handle more than 1A with EV voltage despite their description stating so.

My test setup is two “HV Battery Box + HV-EV transformer” combo linked with aluminium cables, because I’m currently up-ing my grid voltage to compensate for EU loss.

I made the same test with gold cables (1x) and HV voltage (no HV-EV transformers this time) and as soon as I reached 2A (by putting a second battery in the “emitter” Battery Box) they all melted in fire, as expected.

Did I misunderstand something ?

Are you sure it is 2 Amps? Because the Transformers make the whole thing 1/4th of whatever the Amperage was, when you x4 the Voltage. So your Aluminium Wire is doing 2/4th of an Amp, which is just half of what it can handle.

Oh I was not aware of this “1/4th” behaviour between Voltage and Amperage. I’ll test this more thouroughly :+1:

Yes, Amps are the reason you even get Cable Loss, and Transformers 4x the Voltage in order to /4 the Amps, so you get overall less Loss :wink:
