Fuse box question

[doogsey]

Apologies in advance if this is not the right forum for such a question.

I was hoping to get some insight into why the fuse boxes in our flat are the way they are. I have attached a photo which shows an RCD consumer unit, a Wylex / traditional fuse box, and another box which has junctions and wires.

It seems fairly obvious that the box on the right is a newer unit and whenever we've had a circuit trip, we can just reset one of the RCD switches in this unit. I gather that the box in the middle is a lot older and from reading online, people replace the old fuse box with the new RCD consumer unit.

The thing that confuses me is why the old fuse box is still there and wasn't removed when upgrading to the RCD consumer unit, and also what the box with only junctions and wires is for. I'm fairly certain that the old fuse box is still in use as it has wires connecting to the RCD consumer unit, however I can't be 100% sure because we thankfully haven't had to replace a fuse or had a need to switch it off.

Has anyone seen a similar setup before, or know why it might be like this?

The middle box is your main incoming supply and master circuit breaker, then you have your consumer unit and then you appear to have a mess of junctions to connect everything up. My guess is that whomever added the new consumer unit couldn?t be bothered to replace the whole setup and created that mess instead. I wouldn?t have thought it was dangerous but it?s hardly the most professional installation in the world.

Makes sense, thanks a lot!
