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.

    Around 15 metres of tails run up the exterior cavity wall, through the joists then back down inside the metal stud wall.

    The house was built around six months ago by a national home builder starting with B. 

    Reliance on the suppliers fuse is easy to spot,  the lack of 30 mA RCD protection would require investigation that would require damage to the fabric of the building. 

    So what comments would you add to an EICR?

    Is it my eyes Andy, or is that cut-out mounted on a slope?

    Our flush mounted meter box has the cut-out mounted on the chipboard and the split-con cable from the hockey stick which runs up in the cavity feeds nicely into the cutout.


    We had the meter and cut-out moved from under the stairs in 2002 where a metal cased switch fuse is now fitted, well within 3 metres of the cut-out.  The 5 uninsulated earth cores of the split-con were taped up in green/yellow and taken to the earth block by the jointer.


    The photo was taken in 2015 just before an attempt was made to have a smart-meter fitted. The installation failed due to the gas and electricity meters being unable to communicate with each other; the onward communications between the electricity meter and whichever cell site used was good.  So luckily avoided being lumbered with a smets-1 no so smart meter.


    There are some nearby properties built by another national builder who must have positioned the switch fuse on the lounge wall, since there is no suitable location within 3 metres.....

    Yes, they are mounted on a wedge shaped plastic mounting block around here, so the fuse holder leans back to allow the suppliers cables to come up the face of the wall in a plastic conduit

    Which probably prevents the use of the meter tail assembly that connects your meter to the suppliers intake as they don’t line up, despite having been installed by the same supplier.

    My local supplier wont allow a incomer cable to be flush into the meter box, I HAD to take it out of the cavity and put a hockey stick surface pipe on the front of a £700k house.....

    It was in the cavity for about 12" to get into the meter box,  no longer allowed.
