My neighbours mother has problems with nuisance tripping, she has 1 fridge,1 fridge freezer and 1 freezer all on 30ma trip side of cu. dont know why she needs all these but when i tested with ramp test the trip tripped at 21.9 ma. tested mine at home, same make trip and got the same reading, and found out that this is quite normal.Ive moved freezer in garage to non rcd side,and fitted a spur to it, and this has helped, but if the other two are running and she plugs in her kettle the trip trips. I think there are going to be a lot of problems with the new regs on older installations even with rcbos .
Do you not consider there may be a faulty appliance here???
NOT a nuisance trip??
Why would a Kettle be leaking to earth??
As I have mentioned before..
We have had bog-standard Split-load board fitted for longer than I can remember...
With ALL of the kitchen appliances, Fridge/Freezer/Dishwasher/Washing Machine/Tumble drier.....
Bread machine/Microwave/ central heating boiler...
Electric showers.. etc.. etc..
The only time our RCD trips..
Is when the Steam Iron is overfilled & water gets in the gubbins...
Or our old steam iron had a fracture in the water chamber..
i.e. Tripping because there was a FAULT.. not nuisance.
Me moms kettle tripped their RCD a few months back.. Faulty kettle... dripping over inlet lead!!!
NOT an RCD tripping when it shouldn't
I think the main "problems" will tend to be highlighting genuine faults that need addressing!
