Initial verification and testing is mainly intended to rule out installation issues such as faulty connections or pinched wires, to some extent also manufacturing defects (it's rare but cables sometimes do have non-continuous conductors in the middle of a roll, just to give an example).
Ragner,
This happens every now and then, I've had a new roll of 6mm² 2 Core and Earth run to an oven or an electrode boiler, it got that bad that I would Megger the cable before it was even pulled through or I would install PVC conduit and pull in single cores.
I do note however that in the UK, the EICR seems to be the port of call for Residential and Commercial periodical electrical testing, what are your or others thoughts on that?
