Sub mains

[Jpspark]

Hi all,
I’m about to pull a sub main to supply an annex
16mm SWA, my question is how to do use the earth as a 63amp fused isolator switch only takes a Line and Neutral?
or if anyone has any tips or know of a bit of kit that can help? Cheers

Correct, Were you expecting it to switch the earth as well?
It will almost certainly have an earth bar/stud!

What make/model of fused isolator do you have?
Can you post a picture of the inside, etc?
