Meter tail - CU >25m

[sajeel]

It would be nice to nice to know maximum load of house then apply diversity to calculate max load and actual load. Then you can decide 16mm or 25mm with a fused isolator on both sides would be preferred solution. Otherwise distribution board will need sticker isolate elsewhere. You can calculate load by wattage of appliance divide by 230v to get amps.
Ignore some people on here like to slate more than helping it helps their brain disorder ;-)

So, if you were to supply the property with a 63A Switchfuse, are you saying that you would you decide the cable size based on diversity? Also, how would you apply discrimination with your "preferred solution" of a fused isolator on both sides of the cable, in addition to the DNO fuse?
Still, as you say, better to ignore some of us with thousands of posts, as our "brain disorder" stops us from talking sense.

Re: Meter tail - CU >25m

Going back to the tail length issue though, i was doing a bit in my parents house ( a nearly 2 year old new build) to my surprise (never noticed or paid much attention to it) the meter box was opposite side of the house to the CU, 25mm tails running through stud work, joists etc all backed up by the 100a fuse!! Length of run approx 10meters! Barratt House btw

Why not contact Barratt's and ask them what they are going to do about this non compliance tail installation in your parents house!!
Should be interesting to see what they have to say, as the situation will probably apply to every other house of this type on the development!! lol!!

Yep chaps I googled 6181y and even the manufacturers like Batt cable call it double insulated. They then say insulated and sheathed cable! So I stand corrected. Is that pandering to on site terminology??
Guitarist, my point was, has someone who's had a hard time on here posting using a 2nd name because of abuse?

Precisely, as reference to insulated and sheathed cables as "double insulated" is a nonsense. The sheath is merely to provide mechanical protection, and although it may be made of an insulating material it certainly isn't tested to any standard for that.

I don't consider trade banter "abuse" to be honest. Trouble nowadays is that so few go through an apprenticeship, that when anyone says the slightest thing which isn't complimentary, we get told that we're being "harsh" or "abusive". That's the legacy of the modern age.

 

[sledgehammer]

so how has it become known as such?
