wa2ise,
Thanks for posting this.
That "work" is so non-compliant and dangerous, if the supplying authority saw that video, they would disconnect that installation, because it being so unsafe, pending an inspection before the supply is reconnected.
I would seriously doubt that a qualified electrician did any of this work and it screams of a homeowner or renter doing some DIY "improvements".
Having things like seals removed from fuses in the main incoming feed and the meter terminals suggests that the person that did this had no clue as to the legalities of breaking such seals.
Irregardless of the bare live connections, there is no way the feed to that consumer unit should come from that set of fuses and it should be fed from the main incoming box.
I also would have thought that 16mm² 2C+E would have been the minimum size of conductor, unless this is one of a couple of consumer units in the house?
I remember back in the day that Pauluk said that anyone in the UK can call themselves an electrician and that is why he got out of the trade when he did, I mean having to compete with clowns like this, you're in a no-win situation.
The ball got dropped when electrical inspections were no longer required for a significant change to an electrical installation and you end up with things like this happening.
Things like poor terminations (not using all of the conductor material), earth conductors being disconnected because there is an earth fault somewhere, no equi-potential bonding of water and gas pipes, no RCD protection, make this whole thing so dangerous, I doubt there was any testing done before it was finally livened.
Finally a question, am I right in saying there should be a link between the earth and neutral bars in that consumer unit?
