Minor works R1+R2 measurement

[gazdkw82]

I think I may have asked this question a while ago but not sure on what the answer was and it's come up again at our monthly tool box talk.

When doing a Minor works for an additional spurred socket or extra light fitting on a circuit, should the R1+R2 measurement be taken from the protective device or the socket/fitting you have spurred from?

To confirm continuity and polarity

Perzaktly Gaz ( not a spelling mistake)

Before what?

 

[telectrix]

but it's not just the form, it's to confirm that there is a cpc to each point

 

[gazdkw82]

Before what?

Energising the circuit.

My question was more a question of where the R1+R2 was performed

A Zs would confirm the same?

Exactly. So before you energise a circuit you want to make sure their is a fault return path in case there is a fault on the circuit or equipement connected to it and therfore ensuring live testing is carried out as safe as it can be.

So with that in mind what would you do now in terms of R1+R2 testing?

Well I guess the question remains Gaz, do you just test the new bit of cable or the entire circuit, unless you have a test cert of the original it's a mute question, which nobody can give a definitive answer to, yet.

That is not the case at all.
I have already given a definitive answer.
To whit: Do as the form requires, measure the R1+R2 of the altered or extended circuit.

What does the form say exactly Spin? not questioning it per say just need proof, does it say only the new bit? Show me the proof that it's only the extension that needs testing, with reg numbers etc, and I promise I will shut up honest, I'll be a good Boy and not question it again, unless it's to confirm your findings.

It means all of the circuit, after it’s been altered or extended.

Right so that's the entire circuit Yes. from the CU? I only ask cus it has been a bone of contention for me for some time, so just to confirm, you are adding a spur to a RFC you test the whole circuit, so sorry to sound like a dork, but so many people question my reasoning it's getting to hurt my brain cus I believe you are right, now comes the clincher, where does it say this? I need to know otherwise I wont sleep tonight.

Is this thread an actual joke? Am I on @Pete999 's ignore list???

It states this on the MEWIC itself.

OK sPIN thank you very much

My reason for checking continuity of RFC conductors after making a spur from the ring, would be to confirm they have continuity after I have conducted the work.
