Hi everyone. Just been reading through some very old posts on this forum, excellent reading. I then went to a few websites to cross reference the points that had been debated. Here goes.
With 1 mm sq. cable, one circuit may serve up to 1200 Watts (12 X 100 Watt lamps) and must not exceed 95 m of cable length measured without the switch length. However, where there are long cable lengths, use 1.5 mm sq. cable instead which allows a maximum cable length of 110 m measured without the switch length.
Ok here is the problem. If you have been watching the programme grand designs, you may have noticed that some of the domestic electrics are like nerve centers. I am aware of a couple of houses where the room sizes are very large and therefore even 110m wouldn't go very far.
For arguments sake let's say we had a very long corridor. We have a consumer unit and we run a 1.5mm2 T&E, we then come to our end of 110m and so naturally speaking we couldn't go any further. Yet for me to continue i would need to go back to my consumer unit for the supply but would be faced with the same problem.
I know this is a bit way out but is the answer that if you did wire up a very long corridor or area that you would need to feed a cable to a new supply to start you off again. Just couldn't get my head around that one.
Anyway just as a comment, i think on one of the grand design houses they used over 3 Kilometers of cable WOW and they call that domestic, that would have cost the earth, it was intelligent electrics as well.
I bet FWL would have loved that contract
