Could This Be A Fused Neutral?

[SparkyMcsparkface]

Hi, came across this today, double width cutout, never seen it before. Not sure if it could be fused on the neutral or whether I am worrying with no need. Any advice appreciated. (Haven't pulled the cutout obviously, even though it isn't sealed - I have a feeling it might be too stiff to pull out anyway, maybe....)

I wish to state that I agree with the use of the FI (Further Investigation required) code for apparent deficiencies with the DNO's equipment. In principle if fused neutrals were suspected (without getting in to whether this was a reasonable belief or otherwise) then the DNO are needed to verify this, and so further investigation without delay is required. It is also clear that this must result in an Unsatisfactory report.

That's interesting to know Dave. Is that an across the UK thing or just SSE? Also are meters currently meant to be checked every two years? The reason I ask the last bit is I see a lot of meters with poorly installed tails with exposed inner insulation and sometimes slightly exposed conductors at the terminals. I know the logistics of planning to update where necessary must be a nightmare at times, and cannot see how each and every install would actually be checked every two years. Is it not also dependant on whether the meter reader is diligent enough to report all they see that should be updated? I suspect many can't be bothered too!

Edit: I just noticed that you used the word "still" above.

Yes that is across all suppliers, and yes an answer to your question we do rely on DR's to pick this up if they can be bothered.

Just to add recertification, of any meter is an ongoing process been going for donks, it is a requirement by law.

Under ESQCR all neutral fuses were to be replaced with a solid link by 2013. I would think its highly unlikely there is a neutral fuse in there.

Fused neutrals are being replaced by the DNO, but they are Cat B, when identified.

As a matter of interest what is Cat B defined as.

Westie in other words it is not classed as CAT A, exposed live parts, where they have to respond within 3hrs, I think the lead time for CATB is 2 weeks, CAT C , is when they can get there, eg broken tag on the cut out or fuse carrier.

That may be, but the Electrician (in my view) was absolutely right to state that Further Investigation was required (in this case by the DNO). It is also clear that we then have no option but to assess the overall condition of the electrical installation as "Unsatisfactory". As such I feel that the criticism of the Electrician in this instance is grossly unfair as he acted appropriately.

The service levels on cat b are 8 weeks I believe, but the fused neutrals must be done within 28 working days as required by the hse.

Fused neutrals are cat C looked at the template today.

It's been upgrade recently to B.11

It was C8 in an earlier (2013) document I found page 62;

Yeah just looked at my new sheet, quite right.
