Why my breaker tripped?

[sew333]

Hello. Today first time something tripped breaker in my house. I mean i was sitting on Windows 10 desktop ,like always and i hear BUM from fuse box. And power go down. Pc turned off.
I have that pc almost 1 year and something like that never happened. I think there was not circuit overload,because all devices was off,like tv,washer etc. Only pc was on. And nothing get damaged. Anybody have clue why it happened?

To turn back power again i change breaker to up of course. And its fine again.

PC:
Aorus AD27QD
AORUS PRO Z390-PRO GAMING
Aorus 2080 Ti waterforce stock
2x16GB DDR4 GSKILL XMP
9700K STOCK
Seasonic TX-750W TITANIUM PLUS PRIME


Never happened with that pc in whole year. Also pc is stable during full load etc.
Today i just browsing internet and power goes down with tripped breaker.
Pc working like before again. Weird any clues?

Or maybe pc is faulty? I mean some part and it caused that once?

All other devices in house was off,like tv,washer,lights.

could be just a nusiance trip. happens now and then. keep an eye on ---, seeif it holds. or if it trips, keep a record of when and what was connected.

it's very common for a bulb (especially halogens) to trip a breaker when they fail.this is due to the high fault current generated at the time of failure. something to do with ionisation of the gas in the bulb. basically the breaker sees this excessive curent draw and trips, as it is meant to do.

so that halogen bulb when blows its normal that tripped breaker and power goes off ? ( power cut )

 

[ackbarthestar]

Breakers (MCBs) are prone to trip as they are very sensitive to short circuit currents.

Sorry i am not eletrician. So if MCB was tripped it cut power in entire house? So RCB was tripped or MCB?

Generally,
Faults between:
1. Live - neutral = MCB
2. Live or neutral - Earth (CPC) = RCD/RCCB

Somebody from reddit say this to me"
You just confirmed your main (not just a circuit breaker) was tripped while using your computer. This should virtually NEVER happen unless you are fully overloading your main breaker (which by your description you are not). Computers and bulbs shouldn't ever blow a main breaker, just the breaker they are on. If your whole house breaker tripped, either something is wired very very wrong in your house and can cause a fire or shock (kill) someone OR your main breaker needs to be replaced which definitely needs an electrician to fix."

That shouldnt trip main breaker ,when bulb get burned. And i am worried. He is right?

a blown lamp can cause a chain reaction. 5A fuse then 16A breaker, and a RCD. or even a 63A breaker. it's all down to which device sees the fault first.
