Overkill on the size of the cable perhaps ?
Yeah - I think you are bang on with that assessment !.
I recently replaced my original standard length 5 year old tethered cable on my wall box about two months ago.
The black outer casing had developed a few twists and lumps and bumps over the five years.
The last two coils closest to the wall box are never used and where like brand new.
It was only the first two coils that had twists etc.
I replaced it with the longer length cable that would reach any EV regardless of the location of the charging port.
I think it was only another £25 for the longer length cable from memory.
Bit of future proofing maybe ????.
I decided to cut open the OLD cable to see how badly the inner conductors had been damaged by the lumps and bumps in the outer protective sleeve.
The main individual core high load cables look extremely heavy in there carrying capacity, at a guess they look very close to the 6mm T&E inner conductors.
Interesting to note that each of the inner copper conductors are made up of hundreds of very thin stands of wire.
Of course, I expected the cores to be of the multi strand type, but these are extremely thin and in huge numbers.
You can understand the use of wire ferrules being used to make off this type of flex.
The use of high strand multi core conductors to there to help keep the cable some what flexible.
The two signal wires are the complete opposite, very small in cross section of course due to there low load requirements.
Once the otter sleeving had been cut away, in a couple of places, the inner cores had become badly twisted.
At one small section, two of the inner conductors where almost twisted back on themselves.
I will try and upload a couple of images of the cable I removed ( less the damage bits ) and place a small section of 6mm T&E along side so you can see the comparison.
