Hi - looked at job today - kitchen which is in extension.
There is a sub main feeding a separate consumer unit - this is a concentric cable which the installer has split the outer un insulated copper into 2 with 1/2 for neutral and 1/2 for earth.
The incoming supply is TNS
Is this acceptable? I realise the problem with broken neutral elsewhere in install at meter
Would running a separate 16mm earth and using outer concentric as neutral only be a solution?
The intention is to fit new RCD consumer unit on end of sub main for kitchen install. Will have hard time trying to sell new sub main cable
what would you do? any advice or suggestions welcome - thanks
