Hi
can anyone help.

I have just done an extension to an annexe, using 3 core 1.5mm swa for the lighting and 4 core 2.5mm for the ring into a 2 way CED Garage Consumer Unit with a 63A 30mA RCD, 32A and 6A MCBs.

Ze, Insulation resistance and continuity test came out fine testing with a Megger MFT 1553 but the RCD will only trip at 5x.

Any advice please?
 
Ill have a guess, remove bus bar and do a three lead test on the load side terminal screws and see if it trips. This means your rule out any possibility of it being down to the circuit(s) your testing. Coreect me if im wrong though :D

No need to remove busbar. Switching off circuit breakers will do.
