Thats a big run. And a big cable. Will need jacks and strong blokes!

close, but VD for lighting is 3%, so i'd err on the side of caution. better to install a slightly oversized cable than have to dig out and replace an undersised one.
i got 70mm based on 80A demand.
5.6V drop.
I just got an email from the guy. This is the only info i have. I know nothing about whats on site whatsoever so can't comment further .It reads as follows;
I need to put in 5 supplies. One each for the 3 units - these will all be say 3 bed, and no electric heating or showers. They each have a cable run of 75 metres.
One run needs to go to the house - this will be about 110metres, and it will be a 4/5bed house.
The other one needs to go to the sewage treatment plant, which is again about 120 metres, but only needs to run a 200 Watt pump.
Everything single phase.
Why would this be preferable to getting the board in to give new supplies?
my apprentice wouldnt ask that question
The r, x and z colums are values for resistance and corrections when taking into account reactance and impedance respectively. Only need worry about reactance and impedance over about 16mm.table 4D4B HAS 3 columns r, x and z. Which column do i use?
