Not long passed my test but was wondering why it’s okay for a circuit to be over the max zs if it’s protected by an RCD?

not really relevant as even with a high Zs, the L-N loop impedance is independentof the Zs and a fault L-N shoud still trip the OCPD.Simply put really it is not ok. The problem with relying on RCD is it does not really address faults between L-N. In certain situations that can be a problem. Before opting for such a means to say "cover" high Zs one must consider the implications of what would happen in a L-N fault. Could someone be harmed or a fire, in say a combustible environment?
