EICR on 3 year old house thats a rental property. C2 because ev charger is sharing an rcd with other circuits in a split load board.Complied with how many organisations interpreted the regulations at the time of design.
No.high integrity ways available, only practical solution is replace the board or additional board for the ev charge point. Could consider rebuilding the internals of the existing cu, but still time consuming and fairly expensive.
Just generally interested in how the as long as it complied at the time approach works.
Who is responsible for the costs?
