NYY Buried Cable - Legit job?

[OsramMyers]

Hi, Ive had a NAPIT qualified electrician out to install a new feed to the garage along with a new consumer unit in there. Its a short distance of around 6m and the cable he used was a 16mm NYY cable, it has been directly buried around 300mm depth with yellow warning tape, It goes under a few paving slabs but mostly its a graveled area.

Is this installation totally 100% in accordance with current building regulations/standards?

When he came to quote I asked for armored cable, he even specced SWA in the written quote but on the day I noticed it was this NYY cable. He said its all OK and he has passed the Part P certificate onto my local authority. When I questioned him after the job he said its easier to use and bend and things have changed over the years and this cable is fine to use in the installation. He said there is no price difference too.

What are people's thughts?

300mm isn't my idea of a 'safe depth'.

all depends on what you are "depthing" with what. one small depth for man; one huge step for mankind.

probably be fine for 40 years but it's non-compliant with BS7671.

Wonder if it would have been mentioned on the certificate as a departure? Seems like a clear one, even if it's in most cases "fine"

Be interesting seeing the certificate.

Update:

Spoke to NAPIT on the phone and the installation is fine. Because its 300mm deep and its a tough cable its OK. Bit shocked really.

I've asked the electrician to replace it all with SWA anyway as outlined in the quote.

Everything's OK then.....it's a 'tough cable'.

Basically, 'If being installed underground, a cable must be tough'. I like that statement from a UKAS scheme????

I wonder if you would do me a great favour mate.
Can you get them to send you that they are happy with the installation in writing.
It's funny how people like to say things on the phone but when you ask for written confirmation then things go silent..

If the reply you got was from Trevor at napit he's a clueless old fool and a danger to be giving advice

Who, the original Klevor Trevor?

Must admit I would chase them up on this it is a joke.

 

[suffolkspark]

I've emailed them, as a NAPIT member I'm ----ed off to be quite honest. What a joke

 

[suffolkspark]

Nothing back so far.... incidentally their codebreakers book lists pvc pvc cables buried in the ground as a C2...

 

[mattg4321]

Just goes to show what a joke these scams are.

What is the point of all us honest/rule abiding sparks paying out subs every year and having our annual inspections if it means nothing.

The scams are not there for the customer or the electrician, they are there purely to make money.

 

[mattg4321]

OP if you are still reading you should quote them the relevant section of their code breakers book.

I think that would then be ‘game set and match’ and I would expect them to swiftly apologise and say what a big mistake they have made and offer to put it right.

Afternoon all, Napit have just phoned me back, they have thoroughly looked into it, and listened to the recorded call from the OP. After ascertaining the cable type and installation methods from the customer they did infact tell them it was incorrect, however at approx 6 minutes into the call after being told basically the slabs etc all need to come back up to replace it, the OP began asking if it was unsafe or dangerous, which it obviously in real terms isn't, which the tech support told him, and it seems that final part of the conversation was all he then wanted to soak in as it were. This wasn't mentioned to us us full in the posts. They have provided him a follow up call to clarify and given a tech sheet showing that NYYJ is suitable for direct burial, but that's not compliant with BS:7671 unless in a duct as we know.

So overall, seems we didn't get the full picture initially, the installer now knows it's wrong and is rectifying, and Napit have followed it up with the customer too which is good.

Well handled Napit, you shall have another £474 from me next year and a handful of notification fees ?

Great stuff, thanks for the update. Always good to get the full story. Good that NAPIT looked into it.

Would NYYJ have the CCC of an armoured cable or a PVC/PVC cable?

Ref A for cable type or ref F?
