Undersized Main Earth Conductor

Former Community Member
Former Community Member
Hi Folks,

I was carrying out an EICR on a domestic property with a PME supply.

The Main earth conductor is 10mm, the water and gas bonding is also 10mm connected to the earth terminal in the consumer unit.

Would you give this a C3 or C2?


I know there's an equation knocking about for checking main earth conductors however, I'm under the impression that this only works if the bonding conductors are terminated at the MET and not the consumer unit.


Any suggestions will be welcome.


Thanks

    Before DZ says anything, I shall say that the turn of phrase above does not give me much confidence in the OP's credentials for inspection and testing.


    Any road, it's the adiabatic which JP mentions above.
