Changed a CU today. Switched it back on & the RCD tripped when I reset one of the Ring CB's .
I admit I only did a r1,r2,rn test (0.50, 1.48, 0.52) & an IR test (P+N joined & tested across to CPC). on this circuit (& the others). I know I should have done a proper PIR, but this time when I inspected sockets & lights the installation looked tidy, but dont slate me!
I also had the shower, another ring, & cooker on the RCD side but their CB's were off. Would it affect the RCD tripping with these still connected but not switched on or would the problem be definately on the ring in question ?
