It's not the voltage, it's the current you'd want to halve. The wire gauge required to carry power is dependent on the current load. It's why when i first saw these new connectors and the loads they were being tasked with it was a wtf moment for me. Better to just avoid them in the first place though.
It's crazy, you don't even need to know about electricity after you see a thermal camera on them operating at full load. I'm surprised they can be sold to the general public, the reports of cables melting plus the high temps should be enough to force a recall.
