this was only a question trumphy i did not ask to be insulted.
James, I never intended to come across in such a condescending fashion, this was not my intention at all.
I apologise for my comments.
Oddly enough, our TPS cables are marked as to thier size and the number of cores and the types of cores (ie:2C+E or 3C).
Also they have a metre-marking on them, to identify, the amount remaining on your reel.
This comes in handy for stock control and charging out cable lengths used on jobs.
