Hi, Just recently moved into new house ("new" as in newly built). Over the past week the RDC switch in fusebox for sockets has tripped about 5 times. On each occasion there have only been one or two applicances plugged in and drawing power so it doesn't seem likely as if overloading could be an issue. I have tried plugging in and turning everything on to see if it is a particular appliance causing the problem but as is expected I haven't been able to reproduce the tripping. (it only happens when I'm least expecting it!). On at least 2 occasions the RDC has tripped when I have plugged in a laptop but with no other appliance (apart from fridge freezer) turned on. I have never had any issues with the laptop at my previous address. Is this most likely to be an appliance caused problem or would I be better off getting an electrician to check wiring in house? Any advice appreciated. Thanks Rebeller
