Various issues regarding EICR on a MASSIVE industrial installation

[Outspoken]

No...at no point in the OP's question is there any mention of disconnection times,that doesnt mean they are not important,but it does mean the OP has no queries regarding disconnection times.....if you are going off on a tangent and not answering the question you may as well bring the entire scope of an EICR into it,why just pick on disconnection times?

So if you encountered an installation as he has which is all BS3036 and there are clearly Earthing issues, you would not be concerned about Disconnection times...that would be high on my list of concerns along with the functionality of the metalwork to supply an adequate earth path and whether the Earth Loop impedance's for given circuits were adequate..because you can bet if the E/L is up the shoot or there is a break in the metalwork to prevent a complete earth path then the Disconnection times are pointless...

But the OP will have measured that if he's doing an EICR,and will have verified whether disconnection times are met and coded or not accordingly....and as he hasnt asked any questions on it presumably he understands it and likely he does not need telling everything else is irrelevant. If you consider breaking capacities 'irrelevant' than I wouldnt want your input into an EICR.

Of course Iwould be concerned about disconnection times....:banghead:.....but that is not what the effin question is about. It is about whether or not a metal containment can be used as a CPC and whether there is concern over the breaking capacity of a 3036 fuses....according to you that is irrelevant.
