Success! Meter fitted.

[Percyprod]

Just like to thank everyone for their help and advice re by previous post, but contrary to some opinions, man from supplier came to fit meter this morning, and of course it is fitted and all working. He tested it thoroughly (checked polarity with a neon tester at isolator) and fitted the meter. Asked him if he wanted to see wiring certificate and reply was "No, not for a stable". I kid you not! Just as an aside, horses are still alive, but before I retired I was sometimes given a job to connect a rewire, usually after a cut-out change or a service alteration. Companies rules were 'as you are not part p registered you cannot test the installation, so no certificate, no connection'. So if I'd been given this job when I was working I wouldn't have connected it! It's a funny old world. That was before I knew it didn't come under part p, but no more on that please!
Forgot photo of meter etc

He checked the polarity with a neon tester? Very professional, those things are only good for stirring your tea and stabbing holes in plasterboard walls...

 

[Percyprod]

We used them on dno, didn't prove it was live, test lamps for that, but approved for use to prove neutral, eg on pme.

 

[Percyprod]

When working we used these to prove neutral, not live, especially on pme supplies. Approved instrument.

Checked polarity with a Neon Tester, best thing for those things are in the rubbish bin.

The only real use I've found for those things is a quick check on a cable before breaking through the insulation with my probes for a final confirmation.

I use the screwdriver one quite a lot, just the right size for popping out cage nuts...

What do you mean Strima "breaking through the insulation"?

 

[Percyprod]

Not the same thing. For a start there is no metal tip to touch. It is NOT used to prove dead. It also has a buzzer, and as you can see, a test unit. We used the Drummond test lamps as he did, to prove live or dead, which are proved with a tester before and after testing to make sure they work. To check polarity on pme otherwise you need to use temporary earth rod and a lead, which could be a distance from the cut out.

 

[Percyprod]

Watched to end of video, and he is more or less.right.

 

[Strima]

If I need to break into the circuit for any reason. For example you could have three circuits running parallel to each other and I need to alter one of them, I would isolate as normal, use to voltage pen to find the dead circuit then finally use my voltage tester to test for dead by going through the insulation.

Hopefully by that point when I get the cutters out I won't be testing the VDE rating...

I would say he is 100% Right Percyprod

I've never seen a meter fitter or DNO worker ask for a cert on any job. Domestic, commercial, whatever. And that includes times when a specific written request has been sent from them to have an available copy of the certificate on or before connection.

 

[Percyprod]

Sorry pete999, he is right as to using for proving dead, but he didn't mention using it for polarity check on a circuit you have proved live with test lamps.

So rather that trace the cable visually you would rely on a volt stick, as for making a hole in the insulation, don't think I had better say what I think.

 

[Percyprod]

That's fine andy78, can only say what our rules were. Other dnos may be different. If I connected an uncertified installation to the meter and because it was faulty someone was hurt, who do you think would carry the can?

It's not always possible to fully trace a cable along its path. As for making holes in the insulation, if I'm cutting the cable it makes no odds, but I'd rather be cutting the dead one.

I'm curious. How did you use that to test for a neutral...?

We have northern powergrid round here so they are the only one I have dealt with.

I think they have rules that certs should be provided, hence the written insistence I referred to. But what happens on site and on paper are different things.

The onus of any incident would surely be on whoever energised a consumer's system. I have never seen the DNO energise a system, only provide power for it to either a connection block or isolator.

 

[Percyprod]

Open cut out, use test lamps to prove supply is live (using proving unit to make sure test lamps are working) between live and neutral. As it is pme no earth to use to check live. You can then use test pen. If it lights on one terminal and not the other then that is the live terminal. Like it or not, that is one of the methods in the company's codes of practice. You can run a lead to a tempory earth rod, but the unatended end will be live when you test, albeit only for a short time.

 

[Percyprod]

Agreed andy, I worked for enwl, normally connections would be done by supplier, but if already metered, sometimes we would do it, for example, some one buys a house, rewires it and has the service position moved. Jointer or linesman would move supply point, but we would move and reconnect meter. I know, inefficient, but that was sometimes what happened. Like I say, I would have been in deep doodoo without certificate.

i order of merit for safe/dead/polarity testing.

at no.1 we have the tried and tested G38 approved voltage tester.

at no.2 is the ubiquitous volt pen. loved by plumbers and kitchen fitters.

at no.3 we have the neon screwdriver. guaranteed to give you a nasty shock when used after stirring your tea with it.

and finally, the DIYers favorite... the wet finger.

 

[Percyprod]

I'm talking about polarity at cut out, may not be any earth to test it to.

Ahh. I see. You use test lamp first. That will confirm that L & N are present.

When working we used these to prove neutral, not live,

The EA device does not, and cannot, of itself detect anything other than the presence of a voltage on a line conductor. It cannot indicate the presence of a neutral.

then what are you standing on.. the moon?

 

[DPG]

I think he's appreciates the 'proper' method for testing for dead before working on systems, but that you may need to test polarity as a DNO operator when you only have phase and neutral coming in, and so you can't use a GS38 type two-prong tester.
