SWA csa

[Robojin]

I presume all cores on 3 core 16mm or 25mm SWA are the same csa?

and checking my maths, volt drop on a 9m run of 25mm SWA is 1.26v assuming max demand 80A

Trying to talk someone out of costly and an unnecessary CU move, but seems they are determined headbang , and yes have advised that an 80A DP isolator is required

all cores same size. i also get VD of 1.26v at 80a

also it needs a switch fuse, not just isolator

Careful Andy must be the girls you have been seeing. :coat

something metalclad - easier to terminate SWA direct into it

And use the third core of the SWA as earth.
