Eicr coding

[gnselectricals]

Doing a test the other day and found a couple of metal light switches no earth to faceplate just to back box but both lugs were fixed.
What code do you reckon I'm saying 3 but it's a 2 minute job anyway to rectify. Can't recall seeing it before though
Cheers

Is this getting a bit silly or what?
The face plate is earthed via the 3.5mm screws.
As such no code.

What happens to the earth path when it is unscrewed?

As I understand it, the back box does not require a fly-lead if the back box has a fixed lug. My preference is to fit one anyway.
However, the faceplate/grid yolk should be earthed - you cant rely on the fixed lug to earth the switch assembly from the back box via the fixing screw.

When its uncrewed it will be isolated, then re screwed up before re-energising! If its a c2 you need to ref a reg number which you have not done.?

You seem to contradict yourself there. We are not talking about prefrences im sure all members on hete would earth it but were talking eicr coding which need to ref facts and regs

I have already addressed all these questions previously in this thread, so please go back and find them. As for the reg as I said I dont have a copy too hand, but the MIs would be a good place to start.

The requirement is to earth exposed-conductive parts.
As far as I am aware, the steel or chrome plated brass screws provide the earthing.
Yes it would be preferable to take the CPC direct to the face plate, then use the screws to earth the (unexposed) back box.
Belt and braces would be to take the CPC to the face plate and then a fly lead to the back box.

Do we really need to safeguard against someone unscrewing a live face plate?

 

[Plonker 3]

From the previous version of GN 8, to amendment 1 stating the CPC should be connected to the accesory.

I would say yes as a painter could be unscrewing it or the person in the house to decorate round.

I get you drift but if screwed down they will earthed so fully installed should meet all requirements of bs7671 (in the absence of manufacturers instructions to the contary)
The faceplate can become live too seen that before.(Loose cables or damaged insulation)
Whilst I agree with using the flylead. the switch should in theory never be removed live and therfore be safe and compliant. (in the absence of manufacturers instructions to the contary)

Earth this then with a flylead

Why ? It's plastic !!:laugh3:

 

[hotfingers]

Sorry.... Only if it's metal,back box if plastic

Laughing at myself here well spotted Dave I just googled for a faceplate :6:
