16mm T&E to Consumer Unit

[7029 dave]

Probably used the old favourite method of tape

or a switch fuse, with one of them fancy covers.

Hi Guys, sorry haven't had chance to reply... Yes they have taken a separate 16mm earth from main earth block to the C.U. The 16mm T&E goes from a 100A iso just past the meter to the C.U. inside the house, it's not a great job tbh... I'll upload a pic. Point still remains that IMHO 16mm T&E isn't fit for purpose in this instance. I don't really wanna get involved as haven't done any work there and its a ballache to rectify but i guess it's my duty...

That is a proper lash up. No circuit protection, cpc incorrectly sleeved and conductor insulation exposed at the switch.

Winner !

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.

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