had a customer enquirey to change card meters in some flats each flat is fed with 10mm twin and earth and each flat has its own earth stake on fuse fusebox side of flat,each flat has a 30ma rcd inbetween incoming supply cable and fusebox. however there is no earth stake for the incoming supplies to each flat only earth stakes for the circuits from each fusebox, my question is and my thinking is install a earth rod for all supply cables to the flats at the front end of the installation have a 30 ma time delayed rcd for each 10mm cable as it is twin and earth buried into a wall
