Hi all, sorry had probs submitting a post. Ok here we go, have replaced CU and put in RCBO's 6a 32a 40a. all wired in, RCBO cpc fly lead to designated bar, N to its bar. L & N out, correctly wired into RCBO and cpc to earth bar. supply polarity correct. bus bar is solid not flexy. Energised circuits no probs. pressed test button Flash bang on three buzz and fizzl on forth. now MCB side of things work but no operation of RCD. IR test done with RCBO leads and out E L N disconnected. RCBO is a B type WYlex
