How many is too many?

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

If you strip the insulation from the live or neutral conductor of 6mm² T+E cable, you will find that, rather that having a single ('solid') copper core (as would, for example 2.5mm² T+E), it is 'stranded', consisting of seven small copper cores twisted together.

A spur is a branch, using a single cable, from a ring circuit. Since the ring itself requires two cables to be connected to a socket, if a spur also originates from that socket, there will be a third cable - hence three conductors into each of of the terminals. A conduit box is what it says - a box designed to have conduit (plastic or metal piping, to contain cables) connected to it. I wouldn't worry about 'figure of 8 circuits' - the phrase refers to two rings joined together at one point (hence a 'figure of 8' appearance) - but it's not something that should be done (not the least because it makes testing a nightmare!) - I think it was mentioned as a 'tongue-in-cheek comment (since it would require four cables meeting at one socket, hence four conductors per terminal)!

Kind Regards, John
 
Ah right thank you for clearing that up. I have seen spur used quite frequently so I figured I would ask ☺.
