Cable size for electric shower

[AndyMc78]

Hi all,

We are trying to ascertain what size cable we have for our current electric shower as we are purchasing a new one and need to know what kw we can get. The current shower is 8.5kw and ideally we'd like to go a little more powerful. Can anyone tell whether the current cable is 6mm or 10mm just by looking at the attached pictures??

Thanks in advance

If the cables earth conductor is single solid copper ,rather than stranded it is NOT 10mm²
There appears to be more than one earth conductor coming into the shower, take a very close look at the one that is within the supply cable.

I think that looks thin, our 10.5 KW Triton has 4mm² Tri rated internal wiring so I assume it will be the same across the range.
The T&E diameter looks thinner, I suspect that means it's 4mm²
