I dont like Schuko plugs and sockets because I have smudged two of them now. They are not built for 16A.
Schneider Electric has recently discovered an out of tolerance test result in one vendor's plug/cord-set assembly
After replacing mostly all Schukos with CEE 230V/16A I finally and somewhat afraid looked into the mouth of my original EVSE - it's plug that is.
Oh dear, there was a small crater and ring wall around one of the pins looking a bit like crater on moon. Only because the plug was black I had not noticed earlier.
Opening the plug, it was an expensive one, I found they had not used sleeves on the wire ends. One of the wires had turned into a spiral under the screw and all those 16A had to pass through that spiral. It got hot of coarse cindering this side of the plug.
Because crimping sleeves onto the wire ends is so unimaginably expensive we have to life with 10A charging in europe now.
that is indeed.
So I would not put a spell on Schneider because of ... but I would not call them heroes either.
I dont know about plugs on other continents but I know for sure soldering wires that carry 16A is tricky at best. Solder is a resistor and gets hot enough to unsolder. That is why soldering has been banned at some places. Turning a screw onto unsleeved wires comes close to a criminal act.
I cannot imagine many things to go wrong inside an EVSE but wires really can get screwed and that seems to have happened.
