I thought that 3.5 kW is about 13.6A, that is using my physics knowledge (P=V x I) but I'm not an electrician so I don't know if it works that way in practice. If it's safe for 2.5mm circuit operate on 20A MCB so 13.6A should not cause the problem. They rate prysmian 2.5mm cable 18.5A so I thought it should be fine. Regarding cable from house maybe it is not 2.5mm then (to be honest that was a guess), it was wired by electrician so I imagine it was done properly (at least I hope so). I won't be able to change cable from the house but I imagine that installing 20A MCB in the shed should give a sufficient barrieryou're stuffed then @ 3.5kW. that alone is a full load for 2.5mm.. a new cable from house is the only solution. and a 30A MCB is too high a rating for 2.5mm.
It was done by electrician good few years ago so maybe its not 2.5mm, I was guessing, to be honest don't know whyDid you do the wiring for the garage?
It looks like the circuit from your house to the garage needs looking at.
This ^^^^^^You do realise fitting a 110v socket outlet even on its own circuit wont give you 110v? You need a transformer.... Just thought id mention this incase you hadnt realised thats how it works
