Replacing a section of damaged lighting cable with 3C+E.

[bongos]

Im replacing a damaged section of my lighting circuit in two bedrooms because there is no earth continuity.

At present there is L/N/E at the switch. I want to run a replacement section of cable from this switch to the light. I will then continue to the next switch and onto the final light fitting.

As the first light fitting is on the cable route to the second switch, I propose using 3C+E from the intitial switch to the fitting to supply a L/SWL/N/E. I will then use 2C+E to take L/N/E onto the next switch. Does this sound reasonable?

switch--->---L/SWL/N/E--->---fitting--->---L/N/E--->---switch--->---SWL/N/E--->---fitting

Or am I best to just use the conventional 2C+E method, instead taking another 2C+E on the route for the first fitting for my switched line?

Sounds fair enough to me, just make sure that each conductor is correctly identified, as 3&e is brown/black/grey, brown sleeving (tape at a minimum) on two cores and blue on the third.

Why would you sleeve the brown core brown?

bongos - use grey for neutral, not black.

I was wondering that myself when I did it last week

can you post photo's of what you have where? it seems a little iffy by your description...

are you saying that you have "loop in" at the switches, and you want to part convert it to "loop in" at the ceiling roses?
