I am undertaking an eicr on 20 odd blocks of flats and would like people's opinion on this set up
The blocks are separated be about 30-40 meters apart, each in a typical square shape with stairs in the centre
Have external stairwell areas only, a ground floor and 2 other storys on top, each block has 6 flats, 3 on each side of the stairwells
The supplies/meters for the flats are in flush mounted meter cabinets at the bottom of the stairs
1x TPN 60a PME supply for each side, one phase per flat
I'm only testing the landlords supply!
This is supplied by one meter in a block to a small c.u. Then has 2x 2.5mm SWA sub mains to 2 other blocks each, so one meter supplies 3x landlords blocks, these are in small cupboards on each Block around 600mmx400mm
now I'm happy with most things apart from the fact that each flats water supply comes through this cupboard with the small cu in it
The water incoming is plastic but out going to the flats is copper
If the flats are bonded back to their local supply then the exposed copper
In this small cupboard will bring in a
Different earth potential which is simultaneously accessible to the mini cu earth fed from the PME from the other block
What action would you take if you found this
I know it's long winded, sorry just wanted to give a good picture of the situation
