Where is the point at which a higher (but continuous) conductor reading should be considered 'OK' on an EICR?
I know the theory is that it should be between 0.05 ohms, but when it falls outside that, how do others decide when it becomes an issue that must be resolved?
Checking a small flat today, with a single socket circuit - about 14 sockets in total.
r1: 0.7 Rn: 0.84 r2: 1.17
Of course the ideal answer would be to drop every socket and check connections etc...and perhaps do an r1+rn at every socket to try to isolate the issue. This flat is empty so it's probably doable, but in a normal inhabited home it becomes trickier...
Not to mention that unless you FI and then quote for the work you risk not doing much...
The same applies to cpcs where the reading is higher than it should be, but still continuous (And not just because it's 2.5/1.0 cable)...
Is there a rule of thumb people have for when they would accept it without comment, note it but not code it, or FI/C2 it?
