hi guys new to this so sorry if revisiting old stuff.
I need to run a sub main 200M from the service head to a log cabin
Super eco all LED etc, so 40A 9Kw max demand
if i use the cable calculators i get 185mm cable
we all know power networks cover huge distance with 35mm cable on 100A supply
I intend to use 2 core 25mm SWA bonding/earth the Armour at the origin then through a
60A double pole breaker terminating in an insulated enclosure with a 40A double pole breaker
then into a 17th board on a TT system
Your thoughts welcome on how i justify what i intend
any suggestions welcome
The fact that I'm part "P" & NICEIC means I'M authorized not that I'm any good
