Chinese LED ceiling light has : white/grey and yellow wires!

It isn't correctly wired as there is no earth connection.

I think the fitting is plastic, thats why

 

[kate_B]

I really don't know about this.

Yes you are right, I finally managed to get a copy of the instructions. They can be wired either way.

So why is there an "earth"wire from the centre terminal to the (presumably) metal body of the fitting?

OK so which is it?
Is it earthed or not?

Clearly it is so why were you saying it was not?
Certainly looks like the metal backplate you normally find to put inside a plastic enclosure to me.

Don't start on about the colour of the earth wire as this is clearly Chinese and not really meant for our market so does not follow our standards.

There are two photos.

The first photo shows the empty terminal block, and clearly shows an earth wire, suggesting the fitting requires earthing.

The second photo, which Winston is referring to, shows the light wired up with 2 core cable, and thus no earth connection.

The OP asked if this second photo showed it being wired correctly, and Winston said it was not wired correctly as there was no earth.

The two photos are different (look at the LEDs) but similar. They both have a wire connection to the centre terminal to a screw on the base with an earth symbol. They clearly require earthing.

Neither can legally be sold in the UK without the correct wiring colours.

Your right this time Winston1

i've seen a photo of another unit ( not mine) .. In this picture live is grey, neutral is white

Neither can legally be sold in the UK without the correct wiring colours.

Provided the terminals for the incoming supply are correctly labelled then the internal cabling does not have to be Brown and Blue.

One unit does not have the necessary labelling, the other unit does appear to have the necessary labels

 

[winston1]

Your right this time Winston1 as usual.

 

[bernardgreen]

Winston mis-quoted me

Your right this time Winston1

which is un-usual for Winston1

Not disagreeing, but can you please explain which law your referring to that prevents it?

 

[winston1]

I'm not a lawyer so no. I just know that anything sold in the UK has to have the harmonised wiring colours in the mains lead (even the old red, green, black is not allowed).

Mains lead and internal wiring are not the same thing, neither of those lamps had mains leads fitted at manufacture.
