[time-nuts] DC distribution

[Paul Bicknell]

Hi where the wire is too thin for the crimp

I actually strip the wire to long and fold it half 

One reason to crimp is so there is not a hard line for a fracture 
IE a point for the cable to brake  
By soldering the joint you actually introduce a potential fracture point  

It's all my time playing with aircraft and destructive testing  
Sorry it was suppose to be non destructive testing but things brake at times

The idea of using a short piece of thicker wire is a good one.  Thanks
for that!
