Hi,
House I am working on s having a new sp & n supply installed. As a result the new incomer will be approx. 15 meters away, so I need to run a sub main.
Main fuse is 100A so was thinking of putting an 80 amp sub main with 25mm 3 core swa. But got me thinking Is this over kill ad would a 60A sub main with 16mm 3 core swa suffice.
Usual loads of shower 9kw, cooker, micro oven and elec hob, utility room. Normal lighting and socket layout.
Calcs for diversity over 60A, but experience says 60A should be ok.
Customer is running a tight budget as usual!
What do you guy think, 16mm 60A sub main or 25mm 80A?
