16mm T&E to Consumer Unit

[Rpa07]

So have they provided circuit protection or are they relying on the service head fuse.

What a difference a day makes - you don't need photos westie, you just 'sense' it!

Minging that is!!

Ha your not kidding... Can't believe thats someones work thats been put on the customer through the insurance company!! What would you recommend, 25mm SWA on an RCD?

 

[westward10]

When was it done because I would be on to the insurance company. Providing fault protection parameters are met a swa cable, assuming it is installed correctly would not require additional rcd protection.

Well it's not often you see a new TNS service to a domestic dwelling these days!

It was wired about 6 months ago. I had a little chip away of the plaster where it comes through the wall, it is in metal capping. Time to bite the bullet today though. The poor women has been through enough with the insurance company, she has fought them for near 10 years to get the foundations and house fixed so this sums them up!!! Would you just use 25mm swa and keep the 100A isolator as the circuit protection?

Thanks again chaps

No it will need circuit protection. Can you contact the contractor then his/her scheme provider.

An isolator does not provide any protection, it is just an isolator. You need an ocpd.
I doubt that I'd use 25mm SWA unless this was a very large house with a high demand.
A 63A submain with 10mm SWA is normally sufficient for a domestic installation.

 

[hogey]

Yeah like a fused isolation switch, I'm with you. Going to get onto the insurance company regarding it. Nice one fellas.

 

[Toneyz]

need a kmf switch fuse with shield I had to look twice unusual to see TNS NOT TNC-S.

 

[onions1066]

You sure that's TNS ?????

 

[Toneyz]

No, however there is normally PME sticker and earth coming from earth terminal on cut out never seen done like this before

 

[Wilko]

Does look like TNCS to me...

 

[westward10]

Hard to say I would say someone has connected somewhat unconventional.

 

[7029 dave]

I can not see any earth lead for the head or sheath. ?

 

[7029 dave]

Just looked again looks like its poking from the bottom out of the cut out.? pme?

if you can't tell that's saying something take it you've not seen cut out earth done this way ?

ITS WRONG FELLA.

 

[7029 dave]

The met is the cover adjacent to the fuse, if it is genuinely NE linked the earth lead should exit that way.

That's the way I known it to be not sure what's gone on here
