My Contactum consumer unit has two RCCB's fitted, one has seven MCB's off it and the other five MCB's off it.
The RCCB with the five MCB's keeps intermittently tripping out, it can go for weeks without tripping, then perhaps goes twice in a week. As the fridge and freezer are on this RCCB one day I will come home to defrosted food!
When the RCCB trips none of the MCB’s off it trip as well, so I don’t know which of the five circuits has the problem.
Any suggestions as to how I can trace the problem, is a fridge or freezer with an intermittent earth leak fault a likely candidate for the problem more than say a TV that doesn’t use an earth?
Thanks for any suggestions.
