Just a quickie.. Can I change the fuses inside the switch fuse to 63amp from 32amp?
As I am feeding a distribution board off the switch fuse..?

Because I have a 3 phase distribution board feeding a 32amp switch fuse which then feeds another distribution enclosure which has a 20amp radial, and a 16amp, 10amp and a 4amp breaker feeding machinery!
No. This accesorie is rated by MI to 32amp.. Of course you cant. Replace with 63amp switch fused unit!
