They are only really presented to Joe Public by themselves - and, since they are a commercial organisation, it's perhaps not surprising that what they present is somewhat 'biased'cheers john, thats certainly not how they are portrayed to joe public.
The length of tails - usually over 3 metres should warrant a switch fuse unit at the meter position. I think under some circumstances 5 metres can be allowed ...
This twin and earth is presumably a 10 or 16mm2 cable. ... I think the way to solve all potential problems is to fit a switch fuse unit in the meter cupboard.
Seems like a switch fuse in place of the isolator in the meter cupboard will solve the main problem(s).
In relation to all this talk about switch-fuses, it should perhaps be pointed out that, as far as I am aware, this is a 'DNO thing', which has nothing to do with compliance (or otherwise) with BS7671.... And the end of the day you need to compromise and work out what is important and practical (switch fuse)
Exactly - and, as I said, if so, it is almost certainly adequately protected by the DNO fuse as far as BS7671 is concerned.I keep saying tails, it is a 16mm2 T+E as far as I can make out.
Doesn't matter - they still have to be mechanically or RCD protected, or buried >=50mm deep. 522.6.202 - see the note that says "Where indent (i) but not indent (ii) applies, the cable shall be provided with additional protection by means of an RCD having the characteristics specified in Regulation 415.1.1"Did you point out that the tails are (as far as I can tell) in line with the consumer unit? So technically in a safe zone?
