On an eicr we can write LIM for L-N testing and do a test with L-N connected to earth if there's too many electronics to unplug.

What about on an EIC when only doing something like a CU upgrade? Can't do the IR test between L-N with too many things to unplug and we can't write LIM on EIC in the live-live column?

So what to write in the L-L test columns on an EIC?

I know its always good to do the EICR before upgrade, but still got to do the EIC afterwards.

Thanks in advance.
 
When testing on a cu you can do a globe on L to L and earth.
But must show test results .by saying that if you do not take out the items that are in it will give false reading.
 
According to BS7671 an EIC should detail the extent of the work it covers and should include schedules of inspections and test results detailing appropriate inspections and tests which relate to the work covered by the certificate.
Further an EIC should not be used to report on the condition of an existing installation.
As such you are not required to include the results of inspecting and testing existing circuits in the schedules.
Some may argue that you are in fact prohibited from doing so.

If you are unable to conduct an unneccessary test, then it is not a limitation, so does not need to be recorded as such.
 
L&N to earth is not a problem, but i've always been taught that goes only in the L-E column.

Is that reading also accepted in the L-L column?

So we leave the columns blank then? Surely we can't just leave them blank or write NA?

I'm just trying to know what's the best way to fill the form, I know what tests to do and how to do them.

You haven't conducted the test, so "N/A" would be fair enough in my opinion. And in the section of the certificate asking about limitations on the inspection and testing obviously I would note that insulation testing has not been carried out between live conductors due to the presence of connected lamps and loads.

Live conductors to Earth is the most important one for insulation testing anyway - in fact in many countries the requirement is simply for insulation testing to Earth.
 
As far as I’m aware, there’s no British Standard for filling out a Schedule of Test Results.
I would not record calculated results, because the schedule is for recording the results of tests.
I would not use X, as it might be taken as meaning fail.
I would not use / as it may be taken as a tick.
I could use \ though I prefer to use -.
N/A is pretty universal as being taken for Not Applicable.
N/V might need some explanation, but then you might have to explain why the measured value for Zs is below the Maximum allowed, yet it still fails.

Both the OSG and GN3 have examples of filled out Certificates and Reports.
Not sure whether they are examples of how to, or how not to fill them out.
 
Given that the Schedule of Test Results derives from BS 7671 then the stipulations therein should be adhered to. For an Electrical Installation Certificate this means that everything is either compliant or inapplicable.
