Breaker tripped;...serious issue?

[bri160356]

Last night my son lost power in his home due to a circuit breaker tripping;...he had his oven, hob, CH, and TV running the time. He also had his pop-up toaster in operation;...he thinks (but not certain) it tripped when the toaster popped-up/switched off.

Lighting was unaffected.

After re-setting the breaker no further occurrences.

Is this indicative of a an issue with the toaster?...breaker?...or something else?

The house was built in 2001 and I assume the consumer unit is original.

As ever, all advice gratefully received.

Are you suggesting that the oven and hob were on the same circuit as the sockets?

Post a photo of the consumer unit with the lid open so we can read the labels

What letters and numbers are on the device that tripped?

Thanks for the reply.

Son is at work atm,...I’ll get him to photograph the consumer unit and I’ll post clearer info shortly.

Hob between 1.8kW and 6kW, oven between 2kW and 4kW, CH between 0.1kW and 20kW so could well be over 32A so there may be nothing wrong. However it is normal not to have fixed appliances over 2kW on there own circuit. But there is nothing to say you must.

I'm not at all sure about "normal". When (if ever) did you last see a dryer, washing machine or dishwasher 'on its own circuit'?

Edit: forget that - my ageing eyes did not notice the "not" in the statement (thanks to EFLI for noticing!)

Kind Regards, John

Son finished work at 2pm today which was handy;...got clearer info now.

See photos;.... it was the ‘RCD Controlled Circuits’ that tripped;...the oven/hob were NOT switched on so duff info in post #1...sorry for that.

Microwave Oven was on/ kitchen extractor on/fridge on/ freezer on/ CH on/TV-Sky box etc on/Broadband router on/pop up toaster on/ 2 x table lamps on/ Washer off/dishwasher off. Nothing else that we can think of on the ‘sockets’ side of things.

As I said in my thread starter he thinks (but not certain) it tripped when the toaster popped-up/switched off, but after re-setting and using toaster again (and all the other items) no further occurrences.

if the RCD tripped, you have an earth leakage fault, not an overload.

Most often these happen on watery appliances, such as kettles, boilers, immersion heaters, washing machines, tea urns, fishtanks, fountains, outdoor sockets and outdoor lighting or sheds (especially during and after rain). They do not have to be switched on at the time, but they do need to be plugged in or, for fixed appliances such as boilers, the wall switch needs to be on.

Start by looking for any trace of water leakage. If it happens again, UNPLUG all appliances.

It can also be rodent or canine damage to wiring.

Whilst it is certainly true that water-related issues are commonly the cause of RCD trips, so can be crumbs in toasters - so, given what the OP reported, that would be the first place I'd look. If it were the problem, it may just need 'de-crumbing'!

Many thanks for that;...a lot of potential culprits then.

...de-crumbing we can handle!

Whoops now corrected - thanks for noticing!

Bit of burnt toast touching the element. Not uncommon at all.

 

[AndyPRK]

If I was doing some toasting, and I had a power cut or trip, my toast would also pop up, because an electric solenoid (or similar) holds the toast down.

So I'm just putting out there, what came first? the chicken or the egg? What was the cause and what was the effect?


Was the toast suitably brown? or under cooked?

Very true, but that does not in any way preclude the possibility that, if the trip 'came first', that the trip was not caused by something touching the element in the toaster.

At least from my viewpoint, the point is that shaking out the crumbs, and removing any bits of burnt toast/buns/whatever from a toaster is a very simple first thing to do (and is worth doing, even if the toaster had nothing to do with causing the trip on this occasion!).
