Are they? They suggest a C3 observation, which is not appropriate for a compliant solution.They are correct.

(In the interests of clarity, I don't like that "solution" either.)
My apologies. I probably didn't read it carefully enough.The they is the younger electricians in that the regs do allow it.
The Niceic brought out an article in their connections magazine which says the same thing, as long as the cpc is confirmed by continuity (R1+R2) etc and the rcd is checked and it’s effectiveness tested, then it is not necessary to measure Zs as per the regulations.i know plenty sparks over the years who no longer even do a ZS tests & just do rcd trip times as according to them the rcd is the be all & end all...

Circuits without rcd protection requires Zs to be measured by direct measurement or other means.
I’ve attached said article for those who want to have a read ??. for the record, I still record Zs.for years and years one of my jobs as an apprentice was to go round our big job sites and do all the ZS tests Once the subby sparks had all moved on to the next site.
now I would only have to test the rcd
where is the fun in that
