Hi there Simon,
This picture looks rather strange.
Is that cord the factory original type?.
Reason I ask that is because, how many flexes in the UK have a bare, solid earthing conductor in them?.
I thought that that was only used in fixed wiring cables.
Looks like the person that attached that cord could have some colour-blindness issues.
BTW, that cord clamp doesn't look that robust. [Linked Image]
