I have posted a piece here which is also on the TT topic, but is more general and I think a new thread would be better. Your voice is heard. See below.
Those are there due to the lousy standards of the bottom end of the industry Andy. Unskilled and unknowledgeable hardly cover it. Those plier type tools do not make satisfactory crimps ever, even of fine stranded wire, because the "dies" are the wrong shape and the force inadequate. The range of crimps you are talking about is used in many places, appliances included, but rarely as original equipment in cars, because they don't do well in rough environments. We do keep finding wires extended during CU changes using them, and they usually attract a code C2 from me unless they are properly made with the correct tool. Earth extensions are particularly bad! I think that the crimp extension I illustrated above would make a significant improvement to installation time, and even more in fire safety. It is certainly better gripped by the terminals then even 19 strand tails cable, and one rarely finds the busbar connections loose of a similar construction. I would reckon that 50 jobs of CU change would save the crimp tool price in saved time and reduced frustration alone.
