Replacing fuse box with new circuit breaker box - keeps tripping

Anonymous user 03/03/2024 - 3.15 PM

Bought a 'new' house, with 1960s wiring (PVC coating). The fuse box is old - not one with screw in wires though - and looking to replace with a new MCB distribution board. A family member, who is very capable of doing the job, has attempted to replace the board and as soon as it is turned on, it trips straight away. Now while I trust the person to fit it, is something being missed? Why would it trip straight away and is it something that can be rectified without rewiring the entire house? Too much current being drawn? The issue I have is that I don't want the house to burn down with my family inside. There are parts of old wires on every circuit, even the newly wired parts (for convenience and cost). We have redecorated the house and don't want to have to undo all the good work that has been done...in hindsight it would have been better to rewire the entire house...but a little late. Any advice would be really appreciated. We want to get an electrician to come and do a report and potentially quote for further work, but not at that stage yet.
