I know that when rewiring council installs round here they have rcbos installed on the cooker circuits rather than the normal mcbs.
The reason given was to try to minimise nuisance tripping from tenants cookers (which could sometimes be old)
So, just wondering if you got an electric cooker + whether or not its giving you any gyp
Hey mate, thanks for posting
Nah I have a gas cooker and have painstakingly traced the problem to my lights and fan only, and tried the fan on its own which is great its just the lights

So its the braker that trips and not the RCD is that right?, the breaker should be 32A

Does anyone know why this could suddenly happen after years of it being fine??
I know the answer to this I have seen it a few times now and its one that catches a few people out
It could be because you have been running the breaker on its limit for a long time that the breaker can in some cases become sensitive and you end up with it tripping at the drop of a hat
One way to check if its this is to swap it for another 32A that hasnt been running under such stressfull circumstances, like swap upstairs sockets for downstairs and see if it does the same
It could well be something else like the voltage levels or supply parameters have changed but if it were me that would be my first port of call
You should post up a list of exactly what is running on this circuit and the wattage of each device dont miss anything out as you will be cheating your self
Do I win a mars bar now?
I cant work out if you mean the RCD is tripping or just the breaker, when you say the switch in the middle makes me think breaker?? but its unclear
Hey Davey Jones, thanks for this post
I have taken a picture of the box and its the grey breaker switch in the middle(in the crabtree writing bit
Sorry I am no electrician but I am very competent at wiring switches lights etc general household DIY.
So shall I just replace the breaker fuse then? Is this easy to do?
I will try and get a list of all the wattages of the things running on the circuit but without wattages the room has 2 x 1000 watt lights, airforce 2 8" fan, TD Silent 8"fan, 5" system air fan, TD Silent 6" fan, air pump, tiny oil radiator, De'Longhi Slim DES 12 - Dehumidifier and a oscilating 16" fan. My second room is spurred off another double socket in another room but still on the same ring main (upstairs sockets) has a 1000 watt light, 6" system air fan, 6" rvk fan, 5" rvk fan, small oil radiator, mj1000 pump for drippers and a mj1000 pump for flooming the water.
I know this is a lot of stuff but the actual household items that run off the ring main is on minimally like Kettle, Washing Machine, Microwave, Oven but the fridge freezer which is on constantly. When the house I live in had a kitchen extension they used the upstairs sockets ring main for everything for some reason.
I know this is a lot of stuff but its all worked so well for years, but like you say its probably a warn out fuse
I will try and get the wattages together and post back
