Cable sizing

[RBS]

Need a cable to run approx 100m from incoming supply to a new build house,cable will be buried under ground what is the mimimum size cable that could be used to make it comply with the regs? Copper/aluminium? Thanks

 

[plugsandsparks]

Probably better to ask EON

That's like asking how long is a piece of string mate. More info is needed.

No offence, but if you are asking this question on a forum then maybe you need professional help on-site.

 

[Jimmyb]

depends on design current for starter

 

[macca_31]

your power provider will be able to determine what size cable you need, again u shouldnt be running this off your own back etc

why would you wanna do that?

"A new build house" is a bit vague. Firstly how big is it? 8 bedroom? Wendy?
As mentioned there are too many variables, hence there being no '1 size fits all' supply cable to any property that falls under the heading of 'house'.
You'd need to calculate maximum demand, then the DNO will hook you up if they're satisfied you've wired the place up right.

Barn has been dropped and permission has been granted to build a 4 bedroom house,and the nearest point of supply is approx 100m away, around 6k to have cable laid by supplier so was thinking surely that it would be cheaper to buy cable and lay it and let them connect up????

If you're lucky the DNO will accept that but I wouldn't hold my breath for that if I were you.
It's their toy and you can't play with it usually

Again, with the greatest respect, you are trying to lay a cable the DNO have quoted you 6k for and you are asking on a public forum how to do it to save some cash. "out of depth" comes to mind.

exactly Trev....why would they risk losing any profit opportunity here.....and you can be sure that they will have vectored that into the costs......

 

[trev]

Not so much the profit opportunity Glenn. From a "doing it right" standpoint, how would the DNO be sure that there's not half a million tape joints in the buried cable? How would they be sure that the correct cable has been installed all the way along the run?

To me it comes back to the old part p thing, would you sign off a domestic install if you wern't involved 100%? and there's no difference here in my world

ok Trev...i can understand how the DNO would want to be sure of the job being done right.....so working on this basis....how is it that they often shirk their responsibilities when it comes to maintaining earthing arrangements that they have supplied...and are being used by consumers installations...?....and as regards to not signing off work that you havn`t been involved in ...at 1st, 2nd and ins and test.....well those that get up to such stuff leave themselves wide open dont they..lol...
