New build outside light

[clematis432]

Hi, is it a requirement to run an earth wire to outside light(although its double insulated) or is it probably just best practice ? I was replacing my son,s existing outside light on a new build house with a pir security light but found there was no earth to his existing light. Thanks

Nope, in the case of the Honeywell stats, they provide a terminal, although as most of its plastic, its not an issue.

So you are parking the cpc in a terminal that's mostly plastic that is NOT introducing an Earth/

Do they state that stat is double insulated.

How is that Honeywell Stat "double-insulated"??? Isn't it a single insulated control, like a normal plastic wall switch?

Yep.

This could be the epic you guys dream of

@Midwest and Honeywell are in line with IEC 62257-7-1 ... an earth terminal may be provided inside a Class 2 device, see note 3 . Just doing my bit to keep the dream alive. Well, consume red wine at least.

Yes it's not connected, but by it being inside the fitting I believe it makes it no longer able to classed as "double insulated".

So why do I fit light fittings that are double insulated and come with a terminal to park the cpc?

Id like to add that a cpc is not there to protect the cable neither is it needed for fault protection on a cable. Its there to connect 'exposed' conductive parts to earth. Last time i checked 25mm tails they didn't have a cpc within them. You get plenty of class 2 appliances with 2 core flex. I guess they forgot the earths. I agree its not good practice, but in the real world to a class 2 fitting.........

Best option....so that if it's replaced with a fitting requiring an earth connection it's there, waiting to be connected.
There you go.
You can go back to sleep now.

I thought that you were posting up a photo?
You're lucky normally someone has taken it way off topic, once Tel and Pete were posting about what they were having for tea!
