chrome light fitting light switch do u need to earth front plate

[Mick821]

Hi I've been replacing my white sockets and switches to chrome I've done a few of the double sockets, however when attempting the light switches the switches are earthed to the back box but do I need to do the front plate aswell!? there is a designated earth connection on the front plate but I was hoping I could go with out as the screw connecting the back box should earth it anyway is that correct? I don't really know how I would earth it to be honest. Any help is much appreciated photographs attached are current light switch

wiring and new chrome

The switch has an earth terminal so I'd earth it, a short length of green & yellow cable from the earth terminal on the switch to the earth terminal on the back box is all you need.

Thought as much was hoping to get away with it. Can I just buy a piece like that from screw fix or ebay an some wire cutters I assume. Would that just then go in to the back box aswell as the piece that's already in there and then to the front plate. As you can guess I am a complete novice so any help I'm really greatful

Would this do the trick this this HTML class. Value is http://m.ebay.co.uk/itm/221935727856

That's 10mm cable which would be wayyy too big to fit into the light switch terminals.

You don't need to buy any special cable, just use an offcut of the earth wire from twin&earth cable and some green/yellow sleeving.

I don't think you would be able to get 10mm into the terminal on the switch. It seems rather more than is needed. You asked about Screwfix and I'd use their ref 35170 sheath over a scrap of suitable cable. (I am prepared to be told this is wrong but it works for me and the wire is clearly identified)

Haha apologies how about 4mm it's only 1.48 on ebay for a meter an that will do the house I would imagine

Still no, you need 1mm² or at most, 1.5mm²

If you've got an old extension lead or something (with three core flex) just chop that up. Or get down to any electrical wholesalers and buy a cut metre of flex/twin and earth and a bit of sleeving.
