Hi all,
I am working out some cable calcs for an outside lightinginstall in a domestic/commercial environment.
It’s a house with a commercial yard at the back of property,100m away.
The circuit will be supplied form and existing submain.
Now as far as I am aware volt drop has to comply back to theorigin of supply.
However just wanted to clarify, as this sub main appears tohave its own service head and fuse and it is mounted on a southern electricstamped timber board.
There is no meter, it is metered from the house and has a50A breaker supplying from that end.
So in this case is the origin at the house or at thissecondary incoming head?
Would appreciate your thoughts?
Many Thanks
