No, I don't agree. Surely the more you fill the terminal, the better.
I would bend back the ends of two 2.5mm²s making four.
After all, two 6mm²s have fourteen round conductors.
When you say two 6mm cables have fourteen round conductors what do you mean by this? And how can you see this on a cable?
Thanks for all the replies though it's interesting to see people's opinions on this. I am however a little confused on some of the terminology....
What is a spur? And a conduit box? And a figure of 8 extend a ring?
Thanks
