You didn't show it in detail, and how is that plastic box safer than the exposed earth metal connector? Obviously that's up to code, but how is that safer? Earth is supposed to be on metal casings and such so a loose wire can't give the case mains voltage
I know, I had an issue with that part of the footage, So while it is fine for it to be exposed it is much safer to me insulated as in a fully condition there can still be voltage on that earthing conductor, It is also not what it is designed for, the Green Henley’s are double screwed per connection ensuing integrity is kept
