Problem with RCD tripping
Posted 18 September 2011 - 10:21 AM
This morning for example I had the TV on for 2 hours with no problem. Turned the washing machine on - 10 mins later RCD tripped. Turned all power off around house then washing machine on and it worked fine. Turned tv on 30 mins later and RCD tripped. Waited for washing machine to finish then turned tv back on and no problem. Also tripped when I had washing machine, microwave and toaster on. Microwave and toaster together didn't trip.
Also had same problem the other day with TV, oven and deep fat fryer.
I am totally confused as other days I can have a lot on but RCD doesn't trip
Your help would be much appreciated

your RCD may be to sensitive, or it could even be your fridge/freezer on its way out. you turn the washer on and all is fine, fridge kicks in and bang.
where in wales are you?

Agree with everything my esteemed colleagues have said......
I will just add..
the TV (or some other home entertainment gear) is unlikely to be a prime culprit..
Because a lot of this gear is double insulated with only a twin flex supplying power.....
So they have no exposed metal parts that have to be earthed...
so less easy path for electric to flow down to earth.....
If the appliance has a thin flat flex its most likely double insulated..
I would concentrate investigations around your kitchen appliances that do washing or cooking...
the higher power stuff with metally bits and earth connections all over!

If you're not an electrician , the RCD does'nt trip on overload but if it detects a fault . As said by my learned colleagues , often kettle, iron, immersion heater, cooker ,specially the older upright ones, driers and sunbeds .

I had one a year ago. PAT tested washer before use, all good. Tested during use, all good again. When it got to its first spin cycle....pop! It was an old washer so client binned it. Cheaper to buy a new one.

It happened to me once to find an earth-neutral fault. With no or little load RCD was fine, all light on RCD tripped, hob on tripped, and so on...
