Bit of help on voltage drop

[deadmanlufc]

hey there. just a bit of help needed lads.

ive got to run a swa cable approx 100metre out of back of a farmhouse (clipped direct around 2 metre out of house) then run around 80 metre down a field some of cable underground other parts just run down side of garden probably slighty dug in at places, then into old shed, then into wylex garage unit all backed up with 40amp mcb. i am thinking of using 6mm 3 core. just wondered if anyone knows how to work out how much voltage i would be losing ?

i am using 6mm 3 core so i can comfortablely use 9000w power in the shed

i have done a calc but want to reassure myself a bit as i am not confident. :-s

help please

To lower the voltdrop you either increase the cable size, decrease the distance or lower the amount of current needed.

You can never normally do anything apart from increase the cable size as the other two are set for you.

You wouldnt try painting a room with a cup of paint when a tin is needed because it just cant be done
(sorry if this sound harsh)

I shouldnt say this but the cable i would install is a 25mm 2core, but like i said before you need to consider earthing, bonding and protective decvices

Well that matches my calcs and i,m over 40 and happily married!
