Discuss An interesting callout yesterday.... in the UK Electrical Forum area at ElectriciansForums.net
That was before I touched it.What's been Gnawing at the screw terminals !
(or was that just getting it to undo/unweld ?)
Apart from poor workmanship its high time manufacturers put two screws back onto these sort of terminations. The actual length of conductor that enters these connections is pitiful. You'd only need to fart on one to shift it once tightened.
Meter changes will be an issue on a lot of installations, however in wasn't it the callout fault on this job. The tails come from Consumer Unit into Isco's/Henley blocks. It was down to poor workmanship from the electrician that did the work. The rest of the installation is a mess as wellI have just turned up this reference for a trial done on meter tail terminations by the Electricity Safety Council:

For the busy reader the conclusions, observations and recommendations are on page 10/10.
Excellent news the cage type clamp ones were just asking for trouble Imho have they given the MCBs proper screws as well or just the isolator?Friday I fitted one of the newest Wylex boards, they now have double depth tail terminals with 2 screws on each, I filled it with their new mcb sized double pole rcbos aswell,,,, bloody lovely board I shall be using them from here on out
I’ve installed four of the new Wylex boards with the smaller rcbos. As has been said, two terminal main switch is a big improvement (albeit simply a return to the way switches used to be made!).
And the reduced size rcbos , without the functional earth, means plenty of room.
Only downside is the busbar now sits further back in the board so feeding up cables from the bottom is tighter than before.
