Hi
Circuit Info
32a B RCBO Feeding a Combi Boiler through a FCU in the airing cupboard of the bathroom.
Tested at 1/2 Passed tested at 1 > passed reading Oo 20.5 and 180o at 21.3
When testing at x5 the RCBO is tripping but my meter (kewtech KT63) is showing fail >50v
Im assuming that this is because it it requiring greater than 50v to operate
I have tested:-
at the terminals
FCU
At the terminals with live disconnected
" " " " " " " neutral disconnected
all other RCDs (2 in total) in the CU have passed with x1 29.6 & 31.4 and x5 26.8 & 22.3
It is a TT system and the Ze is 81.9
Zs of all other circuits are between 82.1 and 84.7
Have i missed something? or is the RCBO Faulty
