Are you carrying out an EICR or are you looking at a Report done by someone else.
Yes I’ve got Zdb and ka, but I’m on about max Zs left hand side of RCD X1Sorry but I'm still struggling to understand the question. There will be a Ze at the intake, and a Zdb at each sub board. The maximum permitted Zs at each DB will depend on the OCPD protecting the distribution circuit.
