This does NOT mean however that it is unsafe. However your mortgage provider may insist that it needs upgrading. Without seeing the installation if your report only mentions that the sockets need RCD protection I would suggest that it isn't a very good report since 17th edition requires all circuits to have RCD protection unless cables are buried over 50mm deep in walls or are protected in metal conduit or similar. Either change the fuseboard (best done by a qualified electrician) or if you can, change the original circuit breakers for RCBO's of the same current ratings (make sure fuseboard main switch is off though) This just means that your house wiring doesn't comply with the current 17th edition wiring regulations.

Further, I would like to inquire, do we have standard formula for the computation of the ELCB and RCD? if so, appreciate your help. Another, what is meant by 40A/4P/100mA.
