Incoming tails 16mm

[5tan the man]

If a house has dno tails that are 16mm2 tails. What amp iso switch should be fitted ?

 

[Guest55]

Can be 60 , 80 or 100 amp depending on the service fuse size.
easier to just fit 100 then youre covered lol

Do you mean dno fuse size?

 

[telectrix]

if it's just an isolator you are fitting, fit a 100A,that is just it's max. current loading, don't matter if you only pull 40A, 60A whatever , as long as it's not more than 100A. if you're talking about a fused isolator, that's different. the fuse should be less than the DNO fuse, to provide discrimination.
