I changed a consumer unit  a week ago and for the first time used 19 strand tails instead of 7 strand tails. I have to say they are much easier to use and manipulate in tight spaces. I think they are a much better for terminating in a cage clamp as they fill the space under the cage making more contact than 7 strand.


I purchased them from Tool Station and found they were made by Doncaster cables. A bit more expensive than 7 strand but worth the extra money.
