Hi
Really curious question and I hope someone will be able to answer, I have had the first fix done on my lighting etc and I have lots of 'loops' hanging down, I am guessing that the bottom of the loops will be cut and one end connected to A and one to B, on a circuit I would guess that on each light fitting A (from the consumer unit) would be connected on one side and B on the other side and then the B end would connect to the A end etc etc.
How to electricians know which is A and which is B? I can't see any marks on mine, do they put a tester on each end to determine which is which?
