Earths twisted up outside of joint boxes.

[dtec dave]

Why do I keep finding this set up on installations over 20ish years old..was this the done thing back in the day??

Neat Timbo- Never thought of using a surface box in that way - cheaper than a wiska and tough if a PVC box is used - will defo use that idea if the need arises!View attachment 40234

Where's the strain relief on those cables!

 

[Taylortwocities]

Made for lead sheathed cables if my memory serve me well.

This is a lead sheathed lighting box, done properly

It's just a JB in the loft!

Reading this thread. what do people do with double insulated LED downlighters that do not have an earth connection in them? Lap from Screwfix do them, only bad comment is that.

Terminate the cpcs in a Suitable JB

Terminate the cpcs in a Suitable JB

When I think about it, a daft question. I am going to be replacing a surface mounted light in a kitchen and a bathroom. So i will just have 1 JB replacing the light accessible from the loft and the daisy chain 2 core flex to the three downlighter, using IP65 for the bathroom/wetroom. Should have thought more before posting.

What about the earth being present at each point?

 

[Taylortwocities]

The earth will be present at the junction box which is adjacent to the downlight. A short length of 2-core flex used to connect to the Class II downlight.
Same principle as the drop cable in a pendant.

Exactly except I will have 3 flexes into the JB as I am replacing one surface mounted light with three downlighter, or a daisy chain.
I thought as the main JB replacing the light would have the cps terminated there. it would be okay to take three pieces of 2 core flex to the class II downlight. If they were ever changed in the future and required an earth then an electrician could rewire to the JB.

A down side of doing this is I believe that i would only be able to get an R1/R2 reading at the JB.
