200a tpn for house?!

[J.C.E]

Can i scratch your head (bare in mind biggest i have done is 25mm 4core ?)

I am tendering for a big house new build

I think they already have 100tpn
(But in a kiosk 40m away from house)

And i think they are doubting its big enough now (they sent max demand table below)

So they are asking for a price for 200a tpn sub mains to house if they upgrade from 100a to 200a tpn.

Am i right that the swa from kiosk to house (40m through underground duct)

Will need to be 150mm 4c with a 120mm cpc

And its just bad design that the income is so far from the house and needs a swa sub main!

Any update on this project @J.C.E ?

While I personally hope never to have to wrangle more than 50mm (unless tri-rated!) I would be interested how things worked out.
