This looks like an overloaded mains supply - Multiple flats and a Landlord's supply in a Victorian conversion, all running off one ancient supply - there is a 10.5. kw shower in every flat, I am surprised that it hasn't burnt out by now.

2c .04 sq inch. Good for about 140A (but the bottom terminals of the cutout are only rated to 120A max.)
We have something similar here with a similar number of small 2 bed houses fed of a single phase cable. We did a load check over a few days and the maximum recorded current was 85A.
Looking at the photo it looks as if there has been excessive heat near the 4th fuse from the left

There's obviously a lot of chance involved. In the situation we are discussing here, there seem to be 6 flats, each with 10.5kW showers, not to mention anything else - and 3 of those 6 showers being used simultaneously would get you more-or-less to the limit of the supply. However, showers are normally used for only fairly short periods of time. When you say that the cable is 'good for about 140A', is that continuous, or would it be OK with a fair bit more for short periods of time?
