Loft lighting

I have connected two lights in the loft with a switch in the hallway. The first light is getting its power from a spur off a lighting radial allready installed. The second light is part of a loop in system.

My house , by the way, is a new build and all the dry wall boxes have no earth clamps fitted. So, for example, a circuit is continued by the use of choc block connectors.

So, there is no earth clamp in the switch drywall box for the loft. How do I keep continuity for the cpc. Would it be ok to run a seperate conductor from the switch to the first lighting point. And would this have a bad effect on R1+R2 testing?

I thought it might be easier to just buy a bunch of earth clamps and just fit it to the box, if it is possible?

Any help
Stretch :confused:

dry wall boxes don't have a earth terminal, because they are made of plastic and don't need one.
However the switch has a earth terminal on a metal strip which the securing screws pass through. The earth in your cable should be sleeved and secured to this terminal. If your box was metal then you would have a earth terminal on the box and you would need a sleeved earth wire between the two terminals.
The same principle applies to sockets, the only difference being on a ring main there are two cables and therefore two earth wires.
If on a switch there is no earth terminal, then terminate the earth wire in a choc block connector, in case it is needed for later modification
As long as earth wires have a path back to the fuse box that is all that is needed.
I don't think you have a problem
