@SAL65 It's just possible the cable's been assembled wrongly, or mis-labelled. Get hold of a multimeter and use the Ohms scale to measure the resistance at both ends. The Earth pin is the big one in the very middle. The PP pin is one of the smaller ones. Usually these are labelled. Each end has a resistor fitted between PP and Earth. The Car plug tells the car what the cable rating is, and the EVSE end tells the EVSE what the cable rating is, obviously these should be the same!
The PP pins are not connected through the long cable, they are local to the plug & that's it. All the other wires go the whole way through.
For a 32A cable, you should see 220 Ohms between Earth & PP.
For a 16A cable (actually 20A, but used for 16A systems) you should see 680 Ohms.
If you see Millions of Ohms, you've probably measured between Earth & the CP pin, which is the other small pin close to the PP pin you need to check.
So if you see 680 at both ends, what you have is probably a 16A Cable that's been mis-labelled.
If you see 680 at one end and 220 at the other, it's had the wrong resistor fitted and is totally wrong!
But either of these mistakes will work safely, as the current is getting restricted to the 16A amount, either by the car not taking more than what it thinks is the cable's max, or by the EVSE not offering more than what it thinks the cable can take.
