Hello All,
I've recently returned to this country from South Africa and still learning.
I have come across this RCCB, used as a main switch on a consumer unit, for a TT installation on two recent occasions. There is no other RCD downstream and the Zs at socket outlets has been around 0.4 ohms. When did the regs change to the current requirement of a 100mA main switch and 30mA downstream (for sockets etc), as the OSG PAGES 21/22. What would the code be for this, on a PIR?
