Not sure if I post in here or elsewhere (no access to the trainee section as yet, just waiting for details to be confirmed and access granted).
But I had a eureka moment at around 2:30am this morning, woke up and completely understood the relationship between Zs, Ze, R1+R2, why we do R1+R2/4 to get expected reading at each socket, why we don't use Rn and how they relate to the circuit protection tables for maximum Zs allowable - all seems very simple but it's brilliant to actually be able to say to myself I completely understand the whole thing at last!
I was also thinking about two way switching at the same time - I really need to get a life and sleep and have normal dreams methinks!
