I have recently been to a very close fire in a consumer unit. The live tail was loose in the main switch, molten particles had blown through the base of the consumer unit, cables welded together, service fuse had ruptured.

groundhog ,you worry far too much mate chill out its no big deal
quite a few db,s melt its par for the course
it normally stinks of rotten fish
the forensic study has indicated the neutral bar was not screwed home fully and due to the tightness of the fit and the light load onthe unit any problems can sometimes take 2 years to come to light.
Yes I agree,a few years ago a woman rang me as she'd had a strange smell in her home for about a fortnight,it was described as something like tcp she'd looked all over and couldn't find a cause and was going down the plumbing or electrics route.I offered to pop round straight away and found the tails were a bit loose with some charring of the plastic around the main isolator,the house had been rewired a couple of years earlier,but they had recently had a meter change so maybe thats what had loosened the tails.Maybe it would be an idea to find some way of clipping the tails as they exit the cu to prevent this happening.Sorry but that so called forensic study is somewhat floored!! How does a high resistance connection that's drawing enough current to cause the ignition of fire to surrounding combustible material, go unnoticed for 2 years??
If nothing else the heat emitted would have badly distorted the CU's plastic casing, let alone be the source of a vile and acrid smell, for a good amount of those alleged 2 years that this fault had been smouldering away!!
it's a well known fact that tails can become a bit loose over time, due to expansion and contraction of the conductors and the terminals into which they are terminated. this is the main reason why screw terminal JBs have been banned if not accessible for maintenance. also, a meter change may have disturbed the tails. other factors like increased load due to a silly hi powered shower having been fitted might also have contributed to the problem. this was installed only about 18 months ( not by me ). fire brigade and DSNO had attended 11.00pm night before.
