House supply of 10mm distance from transformer 115m

[Richard Knight]

We bought a plot of land over two years ago which had permission passed for holiday chalets. We paid the seller on completion the sum of £3000.00 to lay down electric cable and water pipes to connect us to mains supply. The cable he has installed is roughly 115m from the mains transformer. And it's only 10mm which we are very annoyed with as that is going to seriously limit our electric capabilities.

What is the best case scenario we could expect from 10mm 3 core armored cable from the main fuse in a meter housing next to the transformer and then a 115m run to our property. I believe voltage drop could be a serious issue?

Thanks

We need more information ..what is the installation method(s) of the cable we don't want to assume here.

 

[Richard Knight]

It is laid in the ground without any conduit to the edge of our property. Do you need any other details?

Thanks

yo' ll be lucky to get m0re than 20A, considering VD.

Thats the installation failed from the outset.

What was on paper when you handed over your money ? Was there a specified cable size/capacity of supply in amps ?
What is the size of the fuse protecting this cable at the transformer ?

What did the supplier/seller state the supply would be?

If there is not rated level you could be up a creek without a paddle.

Are you sure its 10mm? How have you measured it?

 

[Richard Knight]

100% 10mm and it says it in the legal paperwork.

100% 10mm and it says it in the legal paperwork.

Yes, but what did they say they would do? If they have done what they promised you will have to get it re-done

 

[Richard Knight]

Yes they have done what they say in the paperwork. Not disputing that, i'm concerned about the usability of it. Which it appears will be inadequate.

I have an option for Scottish Power to lay down 100m of 25mm cable into an existing supply... any ideas on the cost of that, just waiting for a quote.

Exactly what are you intending to install in these holiday chalets, and how many were you intending to erect/build?? To be totally honest, this predicament you find yourself in, is of your own making. You don't lay any cable in the ground without first knowing what that cable needs to supply and doing the calculations. So if you haven't done your homework and given the details of the cable size required to the seller, that's not the seller's problem is it??

What's more, you haven't stated whether this new supply is 2 core, 3 core, 4 core or if we're talking about single or a 3 phase supply!! No wonder you're now in a right old pickle.

a bit harsh. the op bought the land with planning permission already granted. if the seller agreed to install the cable, he should've put in the right size.

If your legal paperwork say 10mm you could argue that this refers to the diameter. If it says 100mm2 or equivalent then you're a bit stuck. A 10mm diameter cable would be 78mm2 (nearest standard sizes 70mm2 or 95mm2). 70mm2 would prob meet your needs over this distance depending on the transformer tapping setting and conditions at the feed end etc.

As far as i'm aware, planning permission does not require electrical details, only the overall details of covered Sq metre age and type of construction etc. All planning permissions, are subject to actual building drawings being accepted prior to building notice approval. Come on now, would you leave the size of cable to be installed up to the seller??
