Insulated tails used to supply flats

Former Community Member
Former Community Member
We have a block of flats completed in 2017 that have supplies to individual flats in insulated twin and earth.

These cables are fed from a switch fuse and then into a ceiling disappearing into the building fabric.

I no longer carry electrical regs books (Approved sparks but fire specialist) but I did flag up the poor way these cables were installed and questioned if they required a RCD as they were not in metal conduit of armoured cables as I normally see.

Was it not a requirement in a 2015 amendment that all cables such as this were protected/RCD?

Many thanks for taking the time to read.

    Yup - note the "concealed in walls or partitions" in the title.


    Actually I think the basic requirement has been there since 2008 (start of the 17th) - the amendment just took away the option to omit RCD protection on sites that were under supervision of skilled or instructed persons (a change which hit a lot of commercial premises).


    Surface cables (whether soft sheathed or in insulating conduit etc) still don't have an RCD requirement .... which is pretty handy given that most meter tails are PVC/PVC.
