    Hi all

    I'm looking for some ideas but communicated at a basic level as electrics isn't my strong point.

    The other night our built in oven had been on for 5 mins and tripped the whole house. I turned it off, reset the board and tried again. The clock etc was on and fine and when I turned on the grill or oven it then tripped again after about 30secs. Reset again and now does it as soon as you switch on the oven/grill. The clock can be on without tripping.

    Any ideas on how to resolve or what it could be? 

    Cheers in advance.

    Hi all,

    I've got the same problem (almost)...
    Moved intro a new house with a built in electric oven (NEFF T1213).

    Top grill/small oven works fine, its just when using the lower large oven things go wrong...
    When the oven light only is on, its fine and if left on still no issues. When move to a temperature the fan starts up and the element starts to glow.
    After a few mins it trips the mains (RCD thing i think).

    I've checked the element, fan motor etc and all looks ok, no visible melting or damage and as i say it all looks almost brand new (ish).

    All advice welcome, thanks!

    Is this circuit on a rcd? Or is the main isolator on a rcd?

    Hope this answers your question if not directly, learning as best i can so apologies if getting the lingo terribly wrong!

    The oven has a local switch (those ones with a red light and a plug beside each other under the sink next to the oven.
    When the fuse goes it only trips one part, thats an RCD (63amp).

    Simplest answer , would have been "Stop using the oven/grill and treat er'indoors to a healthy Kebab/Chinese/Indian/Thai/Steak.. Or take her out for dinner every night.

    I've just moved my oven circuit off the RCD as it kept tripping it - but now it trips the rcd when I turn the oven on
    even when the CB is not on the rcd in the CU!

    How can that be?

    I've had 3 new elements for this in last 4 years - any ideas what could be going on - Takeaways getting abit pricey!!

    Just figured that it's nothing to do with the oven, but any load on that circuit (via the 13A socket on the Oven switch) trips the rcd
    even when the oven circuit breaker is not on the rcd protected strip.

    Any ideas?

    Yes Snail - ramp test the RCD or at least check mA dump to rule out the possibilty of a stuffed RCD

    Sounds like a N-E fault.

    I had omitted to move the neutral across to the other bank - working ok now.
