No reason why not, providing the load with take the reduced fuse.

Have you had a look at the fuse itself or are you Reading the lable on the fuse carrier ,you may find it is already a 80a fuse or even a 60a which I would put money on as it's a flat.

But its sealed

Believe me its going to come to this little cherry again

What seals would these be, cut outs never have them or all the ones I work on anyway .

my thoughts exactly pennywise ,the fuse carrier is marked up at 100A and i have`nt peaked inside yet and i forgot to mention that its a 3 phase service head with Tn-cs earthing if it makes a differance?

 

[pennywise]

Shouldn't make any difference as your only interested in one of the phases.
