So we have a 5kW generator for our film set. We need to get it as far away from the set as possible. As well as leave the option for 25m consumer extension cord for lights and haze machines.
So what I need is to work out the max length I can get with a little voltage drop as possible.
We would not be using all 5kW on set, probably only around 4kW but I would like to leave some headroom.
Am I right in saying that 6 mm\$^2\$ pair with earth will be adequate for this? I have Google'd this for a few days but not found a definite answer to this.
