DNO's isolator

[monkey5]

im changing an old fuse board for a customer and normally give them the number for e.on to come out and install a isolator in the tails (id rather not cut seals and pull fuses!), and they normally come out within a week. but for some reason they have now passed it on to southern electric (customers supplier)- they have told my customer to buy an isolator and they'd come and fit it.

My questions are

any idea what there called? (obviously DP isolator) and where to get one from (ie would a wholesalers stock them - didnt get told till 1730 tonight)

or would a standard DP 100A Isolator like this

Perfect. Wholesalers should stock these as well.

100A double pole isolator and 2 module insulated DIN enclosure.

I had same thing recently with I think edf, customer called them and they wouldn't fit isolator, all they would do was remove fuse while I fitted isolator and refit fuse - it gets hrder and harder to do the job properly!

yeah i know, like i said normally spot on but this time a pain in the A"

how much southern charging for this? the southern Electric meters round here have a built in isolator which is nice.

And if they dont i believe southern electric have a scheme where you can pull the fuse and temporary re-seal yourself.

Isn't it bloody pathetic that this nonsense continues, its gone for years now. The new power suppliers are avoiding the issue, its on their side of the meter , its a H&S issue but they won't address it .

A commitee has been meeting on this and should shortly report their recommendations.

It looks like they will go for Option 1 which is an accreditation scheme for Contractors.

No doubt we will have to pay for it !!!!

Couldnt agree with you more evans, seems ridiculous when you think about it.

Do heating engineers have the same problems with gas meters?

 

[androiduk2002]

No because they have an isolation valve before the meter ! !

 

[wozz]

what about the seals on the meter itself or do they not have to touch these when connecting new pipework?

Don;t quote me on this but I think they're allowed to remove and refit meters. Why we aren;t allowed to screw a cable in a meter is a mystery, especially as nowadays most meter fitters are some random person of the street.

Now I know opinion is split on pulling the fuse, I don't mind doing it - I've got my HV authorised persons ticket so can work on 300Kv if I wanted but not allowed to pull a simple fuse - rediculous in my opinion, but imagine if everyone who currently pulls the fuse or doesn't but does it live using a henley block called the DNO and asked for a "fuse fitter" the waiting list would be 6 months long!!

On a similar note well ish I had a thought about part p, what if every electrician in the country said they wouldn't renew with any scam until the system was improved - they would keep on doing the work but not notifying it, couldn't prosecute everyone and maybe it would get something done!!

They do allow registered electricians to pull the fuse and reseal.

Who is they, and registered with who?

 

[androiduk2002]

They do allow registered electricians to pull the fuse and reseal.

There might be a few that do allow that, there also some that dont, going on what I have read on here and in discussions with my lecturers.

 

[Evans Electric]

Well,no they don't .really Nicey, the legal situation is still " Only authorised persons are allowed to work on network equipment"

Which registered electricians were you thinking of ?

It should be like that but its not ....yet.

 

[niceguy]

A few years ago, there was a document drawn up by some DNO's which "authorised" certain registered electricians that could go to the local depot and pick up temporary seals which allowed them to reseal after they were done.

They would then supposedly follow on to seal properly "when they were passing".

This didnt concern ALL of them though.

Not sure if this took off as most couldnt be bothered to go the official route.

 

[Lurch]

I've still yet to get to a job with seals on the fuse and meter.

So if you was to call them and they verbally told you to pull the fuse, would you ? IF so and anything was to happen (god forbid) who would be liable ? Or would you request written confirmation to allow you to do this ? Before you pulled said fuse ?

 

[Theorysparky]

so if you cannot pull the fuse,,,,see the rating/type

what do you put on the cert ?
