Discuss 16mm tails with 100A fuse ??? in the Electrical Forum area at ElectriciansForums.net
which just goes to prove that a well manufactured CU coupled with competent installation, lasts for years with no problems. now we have to fit metal boxes because neither of the above criteria apply today in a lot of cases.

I am finding this thread interesting.
In what respect? The difficulty engaging with the DNO's? The contradictory opinions?
What would you do?
Personally I would leave the 16mm tails in place if I was happy the maximum load was well below 87A
That's just showing off, is the screw driver there for show or did you use it to disconnect?Here's a pic of the lovely fuse box that was taken out for this job. Wylex plastic front and a wooden back box. The internals look like new

Sounds the best Idea!, since I think it was mentioned that the tails ran up the cavity and over a door way?why not just bung in a 60A KMF between meter and CU. this will make up for the short tails and also give a point of isolation independent of the DNO fuse.
Derating was probably the wrong choice of words. What I am saying is if the conductors are not clipped direct throughout the ccc should be based upon them being enclosed even if it is for a short length.
Holy Maloney crazy Westy had a point.When at college today doing the Periodic course I questioned the tutor on this. He said you were correct

With an older board,I would say that some oxidisation always take place over time.
The board looks to have a extra shiny busbar and fuse contacts
I could very well be wrong and it may be older but I suspect it has not that long come out of the box
induction hobs do not have as big of a load as you thinkWell, I did try to move the tails but only got the 20cm I needed for the new CU and they won't budge any more, although there is slack at the meter. So changing the tails will be mission messy. Tails leave the external chest high meterbox in a cavity brick wall, go up and over the front door and drop down from the ceiling. CU mounted high up next to ceiling behind front door. New CU is in the location of the original fuse unit, at Customer's request. But somewhere in that lot the tails go through a beam I reckon and are jamming up. Nothing I can't sort if I rip into the plaster ceiling she's just had done .
In terms of load, I am sure a 60A fuse would be fine. 2BR mid terrace, newish combi for CH and HW. Biggest drain will be an induction hob she's got on order.
There's no insulation anywhere near the tails that I can see looking from both ends. The tails will be less than 3m long.
