Thanks for that Lec.
The job I've been asked to do is a block of 8 appartments all with night store heaters.
i was thinking a 4c 25 mm SWA from the intake/meter position to each appartment and using metal clad Switchgear and D.B's.
Can you advise if this would be the correct scenario as I cant think of another way to do it.
I wass going to mount the D.Bs in the corner of a cupboard in each appartment and come side entry into one of them and run the 2nd set of cores through to the other D.B.
Seems like more sense than having 16 SWA's in total !
