Identifying electric shower cable size [with pic]

[hyscore]

Hi guys. I had my house rewired coming up to 2 years ago.And I would like to identify the size of shower cable as we are looking to buy a new electric shower.I think it is 10mm but would like to know for sure.
It is marked, Pirelli cables base o 10 6242y bs6004
The outer cable sleeving is 16.5mm x 8mm and the live and neutral is 6mm measured on its outer sleeving.The pic is of what I had left over.Many thanks.

Not read the blurb, but the fact it has a stranded (4mm) earth, it is 10mm. Could also be 16, but most likely 10.

Defo not 6mm, this has a solid earth (single strand).

That was quick thank you very much.

The TLC site shows nominal sizes of their twin & earth as:

6mm² 13.5mm x 7mm
10mm² 17.1mm x 10mm
16mm² 19.4mm x 10mm

6mm has solid cpc so it looks like 10mm² per the above

the live and neutral is 6mm measured on its outer sleeving.

I did use a Vernier to measure it The steel rule was so you could get a comparison.

Measure the diameter of a single copper strand in the phase or neutral condcutors and then count how many of them there are...

Should be 7-strand, no?

I would avoid depending on rules of thumb like this. IIRC at least one manufacturer offers 6/4 T&E as a stock option and will do 6/6 T&E to special order.

Given the limited choice of discrete sizes available you can get a perfectly accurate result by measuring the whole bundle at the point where the insulation stops.

Never come across that, or heard of it.

Obviously seen plenty old school cable, but not new.

There are seven strands in the live and neutral and the diameter is approx1.3mm the earth strands [seven] are about .9mm.Thank you.

OK - you're looking for the cross sectional area of each core. There's a calculator in the Accessories folder...
