EVERYTHING TRIPS OUT WHEN I USE OVEN

[Nicetoseeyoutoseeyounice]

Every time I use my oven everything in the house trips out, this happened about 12 months ago, I bought a new element and it worked fine but is jow happening again.
The oven dosnt seem to cut out if nothing else in the house us on, ie TV, microwave, but have noticed that when the Tv is on it happens.
Is this an electrical fault or do I just need to purchase another element.
Your advice would be appreciated.

Every time I use my oven everything in the house trips out,

I presume it is an RCCB that trips?

If so:

this happened about 12 months ago, I bought a new element and it worked fine but is jow happening again.

It could have gone again; some aren't very good.
To be certain some measurements need to be taken.

The oven dosnt seem to cut out if nothing else in the house us on, ie TV, microwave, but have noticed that when the Tv is on it happens.

This could be accumulated leakage.
I suspect it hasn't got too bad yet but will become worse and trip on its own.

Is this an electrical fault or do I just need to purchase another element.

It could be but, as said, the element could be tested.
Do you have a multimeter?

What is a multi meter? And is the RRCB the mains box ? Excuse my ignorance.

It is a meter without which you cannot (satisfactorily) do electrical work.

And is the RRCB the mains box ? Excuse my ignorance.

The thing that trips; what is written on it. RCCB?

A multimeter, at least, is an essential tool to have if you want to work on your electrics. It is just as important to have that correct tool as it is to have screwdrivers to use on screws instead of the point of a vegetable knife, wirecutters to use instead of nail scissors, wirestrippers to use instead of teeth, and so on.

Neon screwdrivers are questionable from a safety POV as they use your body as a current path, and they are unreliable - to safely check for voltage you must use a 2-pole tester, such as a proper voltage indicator or a multimeter.



This looks ideal for a household starter set - multimeter, voltage indicator and dedicated continuity tester, all in a handy case: http://www.amprobe.eu/de_DE/showproduct/115/Junior-Set/

All in German, unfortunately, as is the blurb on each product:

Continuity tester: http://www.amprobe.eu/de_DE/showproduct/481/TESTFIX/

but it should be available in the UK - the company is now owned by Fluke, contact them (http://www.fluke.co.uk) for info on where to buy.

If not, there are sellers in other parts of Europe: https://www.google.co.uk/search?q=amprobe+("junior-set"+OR+1333)

Right now the English specs are still lurking on the Internet Time Machine from when Beha was an independent company:

Also see another discussion here: //www.diynot.com/forums/viewtopic.php?t=26282 It's a few years old, so specific model number advice may be obsolete (and prices will be higher), but the generic advice is still sound.

Or RCD

Thanks for your replies.
I don't have a multimeter.
As to The photo you show of the RRCB, I have a whole row of these on my board, but unlike when a light trips out, one goes and we flick it back up.
With oven the main BIG switch flicks, like all the others but wider.
What I didn't mention was that when the oven trips, after being on 6-7 minutes, when it is switched back on immediately after flicking the mains switch it never trips for a second time, it stays on and heats up.

Well, in that case no testing can be done and the problem cannot be determined.

Doubtful.

Wider than those in the picture?

Do you mean it stays on for as long as you want or
trips again after another 6-7 minutes?

Almost certainly you don't. I expect they are MCBs.

when the oven trips, after being on 6-7 minutes, when it is switched back on immediately after flicking the mains switch it never trips for a second time, it stays on and heats up.

this can happen when the sheathing has failed, and the insulation inside has got damp. The initial switch-on can dry it out enough not to trip again. It is very common for oven elements to fail and trip RCDs in this way.

maybe look for an original part if you are changing it again, or at least, a very reputable make.

changing the element will probably be easier and quicker than investing in additional fault-tracing, which will be your next step if the problem recurs.

btw you mention the trip happening if the TV is on at the same time as the oven. This can happen when there are multiple causes of earth leakage. For example if the RCD id designed to trip at 30mA, your oven might be 25, your TV might be 10. Individually they might not cause a trip, but added together they will. There are very likely also small leakages from any watery appliances in your house, such as kettle, immersion heater, boiler, heating pump, washing machine, and a combination of several at any time may cause a trip. You need to actually unplug, not switch off, to eliminate them.

To EFLImpudence, yes you are right about the size, the narrower ones are what you call MBCs, it's the widest one at the end of the row, the main one, that trips, all the narrower ones stay in the up position. Also, once the oven has tripped out after 6-7 minutes, when we switch back on, to answer your question, it WILL stay on for as long as we need without tripping again.

To JohnD, we did buy a cheaper version from ebay, I suppose then you get what you pay for. Don't mind shelling out 5 times the amount for a Cannon part just as long it's this that's the problem. Would hate to get it and the same thing happens.
