Should I use 1mm or 1.5mm earth in domestic lighthing?

[midiman]

Hi,

I need to earth a replacement faceplate to a steel back box in the wall.

Should I use a 1mm, or 1.5mm sleeved cable for the job?

Thanks

Either will be fine as long as it's green/yellow wiring or sleeved that colour.

I will go out and buy a metre of 2.5mm t&c and sleeve it yellow and green.

I just want to be safe.

Thanks

Wait for it.......

The earth in the 2.5 is actually 1.5, but 1.5 will be better than 1mm. If you use 2.5mm that may be too big to fit in the switch earth terminal

Hi,

Sorry I didn't explain it well.

I meant I will go out and purchase a metre of 2.5mm T&C so that I get the 1.5mm earth.

Thanks.

Seems you might be safer leaving it alone.

If your spleen ruptures and needs removing would you pick up a knife or a spoon from your local shop to remove it?

Wow I got a dumb from a dumber.

please strip the cable correctly using an electricians knife, dont just pull the earth to split the grey sheathing

I thought it was a copper rip cord - what else could it be used for

Please don’t tell me we are still reverting to the “ your going to stress the copper conductor, therefor decreases CSA, therefore an immediate fire risk.”
I strip it like that, not one of my jobs has ever went wrong

 

[The Ghost]

ever went wrong

These little touches are the difference between an electrician and craftsman.

I am going to disagree.
I still cut a neat edge with my knife at the end of the cable.

If you connect 10 sockets on a RFC and connected them both ways. I bet the resistance of the cpc ring is the same. A lot of rubbish. My college didn’t even bother telling us otherwise.

My college didn’t even bother telling us otherwise.

To be really controversial the training centre here taught to strip it by pulling the cpc! I really don't see the problem with it.
