There's a few more pre change tests to be carried out too. Well at least I do em.

I can't do any tests at the minute anyway mate! [emoji6]

Why is that?

Why is that?

Because I've got his tester

 

[pennychew]

Had a chuckle to myself about that one!

Oh well thats boogered that then, not got one of your own then?

Mine died last week had a few jobs I couldn't shift so put an appeal out which Stu answered. To my enormous gratitude.

Nice to have such good mates isn't it?

Global IR, good chance on an installation of this age the insulation of the cables has degraded to the point there is a high impedance fault between L/N and E. If you don't confirm the IR values are acceptable, the newly added RCD is may trip and you will have an understandably unhappy customer!

Also Ze to check the earth supplied to the property is acceptable?

And?? a bit more regarding earthing

R1+R2 for all earthed points on all circuits, check bonding on all extraneous conductive parts (continuity not above 0.05Ω).

If lighting circuits are unearthed I would be tempted to ensure no fittings requiring an earth are present, although this is more in the scope of an ECIR.

Have you been reading GN3???? LOL your 0.05ohms that referring to the https://www.youtube.com/watch?v=v38PfIVy2rIextraneous parts is it? https://www.youtube.com/watch?v=rnvNfI__kYU

I really want it but I can't justify spending £25 on it when it's gonna get updated before I actually need it!

I've been thinking I should just bite the bullet, but I remember a thread on here not long ago about dodgy copies from amazon.

Was my answer OK then?

I think your 0.05 ohms is referring to the main protective bonding conductors, check out the two vids I sent you that will clear up your answer I hope. The figure for extraneous metalwork is 2200 ohms or 0.02 megohms, the vids will explain better that I can

Those vids are really good,I've watched the whole series of them a few times over now and would definitely recommend them[emoji106]
