First thing, I have taken heavy painkillers, I am tired, and I am autistic, I may and often do blabber on. I will try hard not to.
Okay.
I have watched many YouTube videos about all aspects of the trades, I have even used, or seen people do in real life, but I have always wanted to know, when someone lays wire, first fixing? They often lay down a grey cable with 3 sets of copper wire, 2 are sleeved one brown and one blue, they then cut off sleeves for the bare copper wire and put the wire in the sleeve. I also know you can get the same cables but all are sleeved. I think they are called something like 2 core and earth and 3 core cables.
Questions being is this just a money saving thing, does it make it easier to install if the earth has no sleeves?
Why do we have these cables? What are the pro and cons?
thank you.
