80 amps protects the cables. Are they only 16mm at the meter position?

It could be that, 25mm tails are required for a 100A supply, 80A fuse will not blow if 80A is exceeded briefly, it takes quite a while for the main fuse to blow, or a substantial short circuit current to blow instantly. In fact an 80A fuse can supply 100A for up to four hours (time chart in below document).


The above document also implies they won't fit 100A fuses anymore, but I've never seen that mentioned anywhere else.
 
SSEN also informed me they wouldn't fit 100A fuses any more when I asked (but would fit 80A). The fuse that they installed is marked as 100A though so....

25.4 generated today, 14.2 exported. Still some margin above target pro-rata for now...

Yep, the tails were 16mm, now upgraded to 25mm. Current fuse is 80A. I'm hoping Northern just say it's fine as they won't fit 100A anymore.

The issue is we have two 8kW electric showers and two 3kW ovens so in theory could easily max it out for long periods if we wished even without a charger. In reality we'll never exceed about 12-15kW.

Ironically I have no export limit though.

(Apologies for being off topic).

IIRC, the regs on maximum load have changed to be 'maximum realistic load' rather than the old way of literally turning everything on at the same time.

The fuse, or the fuse holder???

The holder is usually marked 100A, the fuse inside could be 60,80 or 100A.

Sounds like they are happy with an 80a fuse in that region and cant be a bad thing if they have installed 25mm albeit a little overkill. It sounds like the charging units need to govern for this flexibility if the DNO are concerned about them?
 
Another wash out day.

I wonder what I have then as I requested 100A and SPEN did the swap 1st Sep 2023 but didn't mention anything about only fitting 80A.

If its a Henley cut-out with a 100amp sticker on, your other indicator is 25mm tails. You can take a picture but as above said the only way to know the fuse rating inside is pulling it and seeing which you wont be allowed to do.
