And that's scientifically proven (in 73.67% of cases )the main problem, IMO, is the fact that main switches and RCDs will only accomodate a very short length od conductor in the terminal. anything over 1/4" leaves copper showing. having 2 screws and at least 1/2" of copper in the terminal will cure 75% of the problem.
