Evening All
Does anyone know if a plastic outside light needs an earth? The entire shell is plastic and as far as I can see the only metal parts are where the
bulb screws in.
The reason I ask is there is nowhere to attach one and the previous light (metal) did have a location for one

Yes it does it will need two wires live and nuteral
There is usually an earth terminal, even if it serves no function.
If not pop the bare earth wire in some sleeve and fold it over/tuck it away. There should be instructions with the light fitting which overrule any
regulations.
The light will need to be covered by an RCD for safety. Many properties had split load boards fitted about 25 years ago, where power circuits were on
an RCD and the light circuits were not. So do check.

Our house was wired like this!
Re-wire with a new consumer unit corrected things.
Thanks for the replies chaps
Apparently the plastic light is double insulated so doesn't need an earth as its class II? I have wired it up leaving the earth unconnected and
covered up and it seems to work ok.

I have sorted a few, by adding an extra RCD in the board, or making the whole board protected by the one RCD. Or even swapping the non-rcd breakers for RCBOs. Saves the client a small fortune.
My nephew has just bought a flat, no RCD at all in the board. I will replace the mainswitch with an RCD for him. Simple, and with a small number of circuits, quite acceptable,
