UK Can anyone tell me what is wrong/incorrect.

Basic insulation


Or is this a trick question?

 

[James]

As above plus
grey should be used a N with blue sheath.
armour is not earthed.

 

[westward10]

Perfectly acceptable to use black as the neutral conductor providing it is correctly identified.

 

[buzzlightyear]

No switch fuse then for the feed then.
What is it feeding.

 

[mainline]

armour is not earthed.

It maybe at the other end.

Basic insulation

In an enclosure ?

 

[DefyG]

In an enclosure ?

Or not as the case might be.

Think there was a debate previously on the forum as to whether a meter box is considered an enclosure because it is lockable (don't laugh) and a key is needed!

The supply is using black as neutral and grey as earth. I would seriously question the competence of someone who cannot even get that correct.

 

[DefyG]

Probably 16mm comparing physical size with the Blue tail and the G/Y but not necessarily incorrect.

 

[DefyG]

black as neutral and blue as a line.

Blue? looks like Brown to me!

 

[mainline]

Blue? looks like Brown to me!

It was from a post.

Could someone please tell me if this is right or wrong please.

Right or wrong please? , if wrong, what needs to be done to fix it? thanks in advance.

Things wrong in this picture;

1. Basic insulation showing (meter cabs are not considered suitable enclosures) interestingly site applied insulation (heat shrink) is no longer classed as suitable in an application like this either.

2. Black being used as the N (personally don’t see a problem with it and I’m not aware of any regs which explicitly state black cannot be used as a neutral) but the NICEIC ran a campaign to “de-neutralise” the black. Bigger problem IMO is no sleeving to identify it as a neutral.

3. Difficult to tell from just a photo but that doesn’t appear to be a 25mm SWA and the cut-out says 100A fuse fitted. So OCPD is too large for cable.

4. Whilst not a 7671 reg most DNOs/DSOs specify that meter tails can only use the cutout fuse as an OCPD where the tails are less than 3 metres.

5. SWA braid is not earthed.

6. SWA is not terminated correctly.

According to NICEIC and Select it isn’t classed as a suitable enclosure as non-skilled persons access the enclosure regularly/to read the meter etc.

Still not done properly though, pretty bad practice earthing the armour from the far end of the circuit.
Zs of the braid would be significantly higher.
And installed contrary to manufacturer’s instructions.

@Penguin are you asking to see if we know or because you want to know?

3x 16m showing on pic.lash up job.
Seeing with my big eyes.

I hope we haven’t just done someone’s homework for them…..

 

[pc1966]

Glanding the cable to a metal fused-switch like the Wylex ones would have been far better, then double insulated tails to the meter.

It looks like the "filler" insulation around the 3 cores has been clamped or similar - wonder how that dent happened?

I could only muster up 5 issues, but apparently there’s a 6th.!
So I opened up the challenge to you guys.

 

[SJD]

I'm not seeing any strain relief on the SWA cable.

I'm glad it Xmas, what time is blanket blank on.

Morcombe and Wise, Two Ronnies???

Might I direct you fine gentlemen to another thread….

Littlesparks advent 2023

Something a little different this year…. Not that I’m running out of songs… but I thought this might cheer a few folk up. classic comedy sketches from either Christmas editions of shows, or something nostalgic that is always shown on tv at this time of year. First up…. The absolute kings…… it...

Didn’t even see that dent/damage.
Looking at the size of the damage, it could have possibly been some sought of over tightened Earth strap? (But why)? I’ve run out of idea.

Merry Xmas
