Oh and I forgot to add, in GN3 , it clearly states that if test method 1 is used RCD's should be removed and not subjected to test voltage

Hey all, Ive noticed alot of you are fixated and worried about pumping 500v through a consumer unit with fear of damaging elerctronic equip. In most cases for newly built electrical installations all volt sensitive equipment/IT equipment are capable and designed to withstand 500DC. If you just want to be on the safest side simply switch off mcbs that are connected to such equipment and perform your IR test as normal from output side of Main Switch.
