Even if you use long lead method (R2) to calculate cpc, you still have to 'power down' to determine R1 and Ze - you may as well just invent a figure for Zs, jot it in the form and be on your way lol

well....it was actually for that shanky article to work out....

however R2 is adequate for condition reporting...together with Zs...so by means of a breakout box/prods as required...you wouldn`t need to power down...would you....i just wanted to see if he could work it out...

you would need to power down for your end to ends (ring) and IR as usual but....using this method you cause minimum disruption ...

There's been a lot of sniffing around in this thread but not for likes and thanks

...and for Ze

well...if you cant power down then UV is OK for condition reporting...

in other words you report/note/record what you were able to see/measure....

yep lims agreed

Come to think of it I could phone the customer and get him to run round with a tape measure (I know the resistance of cables per meter), then I could fill in the EICR from my comfy armchair at home while watching Columbo!

You can get a Ze value by "enquiry" to fulfil the EICR requirement! But then it also wants you to prove (tick) that you have "connection/continuity" of the earthing conductor (and bonding conductors) ..... and as we know you can do that live! Or have I missed a trick/technique somewhere?

well you could do....but then you`d be missing the all important inspections wouldn`t you...

If it's TT then Ze by enquiry will probably be a value of 'how the ferk should I know!

probably?

christ even the IET & NIC cant agree on what the max value should be....
