Re-connection

[gselectrical]

Evening all.

Have been asked by a landlord to "megger" an installation and provide a cert proving its safe. DNO have apparantly requested this so they can re energise a supply that has been disconnected following the previous tennant not paying bills.

When he says "cert" I am assuming he means a letter stating that insulation resistance testing has been carried out and the results are satisfactory.

Is this correct or is there a cert to be provided?

Cheers. GS

You cannot provide any certificate as you won't have carried out any work on the installation. What you can provide is a Periodic Inspection Report. Many people (including DNO associates, who perhaps should be better trained to know these things) confuse a PIR as being a certificate, which it is not.

I would recommend to this Landlord that he has a thorough PIR carried out. This will serve the dual purpose of allowing the supply to be reconnected and will see him through for several years ensuring his Landlord responsibilities are met re electrical safety.

I had to do exactly the same two weeks ago, I used a green pir did all dead tests and made sure that it was clear on the cert that it was only dead tests. Did think about only IR, as asked, but thought cya. Also recomended full test when power re-applied as no existing certs were available to me.

How on earth does an insulation test prove that an installation is safe to put back into use, It requires a PIR otherwise you leave yourself open to blame unless you make it clear in writing that it is all that has been carried out at their request and that you are not responsible for any other defects within the installation.

Is this a new thing?

Why insist on this just because an installation has been disconnected due to non payment of a bill? or did the engineer who disconnected it not like the look of the installation so reported it as substandard?

I've never heard of this before. I have even had the supply re connected to condemned installation before, though to be fair that was on the understanding the property was going to be rewired (which it was)

This is to remove any responsibility for the installation from the supply company. There could be live ends in there etc.

Asking to " Megger" it used to be the criteria for re-energising, perhaps it still is , the old "Contractor's Cert" has dissapeared, that was what they used to ask to be filled in .

I've had this also....for a property that was being refurbished.

So I ripped out the old CU, put a new one in with 1 circuit feeding a twin socket.

EIC with dead test only, live tests carried out after the main fuse was re-instated....

then I did a complete rewire and another EIC..

But in your case I'd do a PIR stating that you've only done the dead tests; you could calculate the Zs if you want using the DNO maximum Ze for the type of installation!

if the property is empty for a long time or the bill hasnt been paid in ages the supply can be disconnected, ive had to do a few for letting agents when previous tenants left owing money and property wasnt filled for a long time.

Yes, I have not come across this either. The installation itself could not have "changed" between the period of disconnection and potential reconnection, seen as nobody has set foot in the premises for 2 years.

Fair enough if the supply had been disconnected because the installation was condemned but otherwise why insist on a PIR?

cables do degrade over time.

and what if there was a water leak? 2 years or leaking water onto electrics wont be safe
