That CoC in the screenshot is appalling, at a glance there's at least 8 omissions on that page. Whoever issued it was half hearted to say the least so I'd also take any info given with a large pinch of salt.

I'm also a bit confused looking at the third photo, it looks like it might be a TN S supply that's simply not got the earth connected but it's a bit difficult to tell from the photo. Also not sure what that blue MOV looking device is there for either, I hope that's not someone's idea of lightning protection......
