Q1. When crimping 2.5sq.mm T&E, blue crimps are used for the 2.5sq.mm L and N, but should red crimps be used on the (smaller diameter) earth wire?
Q2 I notice on my newly acquired ratchet crimpers that the depressions in the jaws (where the crimp fits) are smallest for blue and the biggest for red (yellow in the middle). Thus seems c*ck-eyed to me. Surely the smallest should be red (1.5sq.mm), followed by blue (2.5sq.mm) then yellow (4sq.mm). Are the crimpers incorrectly marked (just bought them from TLC) or am I missing something subtle?
Cheers
