Didn't notice. I could unscrew everything again and look if it's important.

 

MrChips,
Is that a BARE copper Earth wire I see in your pic of power point? MY god, that would NEVER be allowed here. All conductors must be insulated,active neutral and earth. How would you prevent the BARE earth wire accidentally coming into contact with the live power?
Same with the other pic of power point showing large length of bare wire connected to terminals.
That sort of work would earn the "sparkie" a huge amount of demerit points not only from his boss but the inspector!
