Breaker keeps Tripping

[united4ever]

My Electricity breaker keeps tripping about 8 times a day It also happens in the middle of the night when we are sleeping, happens when we are out so times when we are not using electricity. Usually just a case of flicking up the breaker switch however this morning the switch wouldn't stay up (instantly switched down to off position) so for about 2 hours we had no electricity. Unplugged everything and kept trying to turn it on. After about 2 hours it stayed on though there was no obvious reason why.

Had a mate look at it who is a retired sparky - he tried isolating it and read the currents of the wires going into the breaker which were normal he said. Couldn't really solve it but thought it might be the breaker switch itself. Said to keep an eye on it and he could order a replacement switch.

Anyway, any experts got an idea what could be causing this? Also, if I want to get a professional in to sort it how does it work - do they come and give a quote to solve the problem no matter how long it takes or do they agree to work on it and charge by the hour until it's done. I'd like to know how much it will cost upfront and want it sorting once and for all.....but the guy who came round today spent an hour trying to isolate the problem and I can imagine a lot of it is elimination and head scratching - don't want to pay hundreds and then the electrician fob me off with some non solution.

I live in a 2 bed new build flat (4 years old). We don't use excessive amounts of electricity.

Thanks in advance

What? This is just a fault that with the correct test equipment should be relatively simple to find.

What if the EICR doesn't pick up the fault?

I WOULD CHECK THE MCB AT 1ST INSTANCE might save alot of fault finding

Get an electrician, a proper one! to test circuits and the Rcd. Job done.

Well yes a simple ramp test on the RCCB would be the first test any sparky should carry out.

If your test results for the fixed installation are within spec, then there is no possible reason that a healthy RCd will trip.
Unless there is an obvious wiring fault in the CU.

Siemens RCCB breaker, Also says next to the switch 80amps and has written 5SM13 317-0. The lights still work when it trips. Will post a picture tomorrow.

In a four year old flat ?

Or a faulty appliance being plugged in, a time clock or thermostat turning a faulty appliance on. The list is endless a fault won't always be present on a circuit which is why a EICR may achieve nothing. But the RCCB keeps tripping even though a report says there is nothing wrong with the installation.

Don't siemens still label their RCDs RCCBs?

Maybe seems odd to me I would be guided by the BSEN number personally

but however you label it, as Rich.250 said the circuit affected need identifying and testing, along with the RCCB. If the standard tests show a problem then great, if not then you need to look further.
Now all the OP needs is a spark who knows what he is doing

btw. a question for the OP - does it trip more when (or after) a lot of rain and do you have any outside sockets or lights? Or perhaps a bath or sink that has leaked recently?

Its probably a split load CCU installed under the 16th ed. when the electrical design for the flats were put forward.

There are about four or five possibilities it could be.

Try this one for starters.

Switch off the dish washer/ washing machine at the local switched fused control unit. This will determine whether or not you need an electrician or an appliance technician.

Not disputing that, it was in reference to the idea of getting a EICR carried out to find the fault.

Could be a 16th ED CU?

It may be sound advise to get a good electrician ,but his next problem these days would then be.
How to be sure he's got one :smilewinkgrin:

Yea don't comply unless we label them 7671 is 3 monthly they state 6 Monthly
