Shower and cooker circuits shown as 2.5mm2 on shedule but overall condition satisfactory

[UKMeterman]

I am reviewing a EICR for a property I am buying. The vendor has had the EICR done, but both the Cooker and Shower are on 40A 60898 B curve mcbs and the cable type is shown as 2.5mm2 type A install methord C. I suspect a clerical error but as it is in the vendor document pack what would you suggest? The cooker is a four ring built in electric hob. The shower is an electricaly heated shower rateing of which to be checked tomorrow.
All the circuit insulation measurements are 500M ohm which is a bit sus.

Go and verify it.

I'm guessing this is the value at which the inspector's MFT tops out.

I don't see the 500 Meg ohm as being 'suss' why wouldn't it have been assuming this is just a reading to earth.

I was guessing it seemed suss as >999 is the sort of reading a lot of people would expect when results are the same on all circuits. Stands to reason the tester measures a maximum of 500mΩ.

It is 500M for both L to N and L to E

What's 'suss' about that?

 

[nicebutdim]

At 500V this tester measures a maximum of 500mΩ, which seems quite reasonable at 500x the minimum acceptable measurement.

For an EICR I would question whether they really disconnected all connections across line and neutral to achieve an L to E reading.

From information provided by the OP, it looks as though the EICR raises a number of questions about exactly what 'testing' & 'inspection' took place.

my problem here is that there is a reading from a 2,5mm on a 32a breaker.... not ok sorry just re read 40a breaker definately not ok
