I guess you and I have a different view on the triviality of using incorrect formulae.
No, I imagine that we probably have the same view on that. However, I would suggest that when EFLI wrote "Zs=PEFC" he was not specifying a formula but, rather, was using 'shorthand' for "Zs corresponds to PEFC" - and, in context, I imagine that the great majority of readers, including yourself, actually understood that.I guess you and I have a different view on the triviality of using incorrect formulae.
You reckon they can take 240V AC but not 250V DC ? That's the reason for not using 500V for IR testing as I specifically want to avoid disturbing lots of connections.
And in that one statement, you demonstrate beyond any doubt that your opinion in this thread can (and should) be disregarded. Anyone who claims that a dismantling operation can be done without any risk whatsoever of introducing a fault that wasn't previously present is a danger to himself and others.Why do you keep going on about risks? There shouldn't be any.
And those readers who don't understand that and are hoping to learn things?No, I imagine that we probably have the same view on that.

Oh - I see.And in that one statement, you demonstrate beyond any doubt that your opinion in this thread can (and should) be disregarded.

Yup, you don't see what I wrote. You've addressed something I didn't mention at all, drawn incorrect conclusions based on incorrect assumptions, and are using that to suggest I'm trying to do something I'm not.My apologies - I hadn't realised you were opposed to any proper testing ever being done, and had set yourself against the prescriptions of the Wiring Regulations, the advice of the Guidance Notes, the accumulated wisdom of the text books and the teachings of lecturers.
Yes indeed, what would a judge think if in doing intrusive testing I managed to introduce a fault that fried a tenant ?Wonder what a judge would think, if you fried a tenant?
You're entitled to that opinion.IMO a full EIC is not warranted
He would probably conclude that you were not competent to be making testing decisions or carrying out testing.Earlier, askedYes indeed, what would a judge think if in doing intrusive testing I managed to introduce a fault that fried a tenant ?Wonder what a judge would think, if you fried a tenant?
Zs = PEFCJust to check, Zs = PFC measured at the outlet
Zn = PSCC
Higher of these = PFC.
Zs/Zn and PEFC/PSCC have different dimensions....Zs = PEFC
Zn = PSCC
Ah, so we now get to the nub of it - you believe that "fully qualified" people are incapable of creating faults during testing. A belief that makes you dangerous, as I've mentioned earlier.He would probably conclude that you were not competent to be making testing decisions or carrying out testing.
You're welcome, but I fear that he might 'have you' again - 230/Zs is not a 'product', it's a quotientI apologise. I was merely using the same format as the OP, albeit technically incorrect. Nevertheless, thank you John. However, does a Zs of 0.23Ω not equal a PEFC of 1kA (I suppose not semantically).
I should have written:
230/Zs = PEFC
230/Zn = PSCC
(Where '/' means 'divided by' and '=' means 'equal to')
Greater of these products = PFC
Depends on your definition of "required".Personally I fail to see why doing testing over and above that which is required makes me an "incompetent and dangerous landlord".
