Is this ceiling rose double insulated?

[aliasx51]

I bought this ceiling rose off Amazon (http://www.amazon.co.uk/Modern-Antique-Brass-Ceiling-Lighting/dp/B00CJ9GE9Q):



It's not like others I've seen as it has a black input sheath to a connection box, which also closes over the top. Does this mean it is double insulated?



Thanks

No, it's metal with an earth connection, which must be connected.

Alias - if you really look at a metal rose with an earth symbol and a visible G/Y conductor attached to it, and wonder if it is double insulated, please abandon all ideas that you should be doing any electrical work whatsoever - you clearly don't have a clue.
