Just Had A Power Outage. Should I Be Concerned?

[chicat]

Just this Tuesday I had an electrician do an inspection and fixing and replacing some things.

Just today my house had a power outage.

Does anyone think this may have something to do with the inspection I had this Tuesday or was this just the usual appliances being overpowered (thus causing outage)? Thanks.

Did you loose ALL of the electricity in your house?

just the usual appliances being overpowered

no, what actually tripped? can we have a photo if possible?
If it is usual for the circuit to be overloaded there's a problem with your installation. If it's the RCD tripping it may be a problem with an appliance.

Did your neighbours also experience a power cut?

Pete999,
No, not all of the electricity. Most of the power was lost but not all per se. I remember my oven (and I think the light in my bathroom (where the box is located)) had power.

Johnduffel,
It doesn't happen too often so far. It was the RCD tripping. Flipped it back up now.

Davesparks,
I don't know because it was still sunny where the power outage happened. So I couldn't tell if my neighbours experienced a power outage or not. I don't think so, otherwise we wouldn't have needed to untrip the RCD. Usually if the whole neighbourhood experiences a power outage the power comes back on its own.

Hi - if you've had your RCD trip and you've had to reset it there is likely to be a fault. It's possible it's an appliance or it can be the wiring that's faulty. Sounds like you need to call your Electrician back for a look.

Hi,what box is in the bathroom?

Wilko,
This is a stupid question but what is it that makes an appliance the cause of the power outage? Fuse overload? Too many appliances using up power?

Peg,
RCD Fuse board is what I meant.

 

[johnduffell]

in simple terms, an RCD compares the current flowing in the live and neutral and trips if they differ much. In normal circumstances it would be more or less identical as all the appliances use those conductors for power only.
However there is a third pin (earth) and also a lot of other conductive things around, including yourself, so if something is wrong thre are plenty of opportunities to find a current path another way. Obviously that's not a safe situation to be in.
If that happens, whether it be through the fixed wiring or through an appliance, the RCD will trip. This is to keep you safe and also indicate to you that there's a fault that may cause a danger so needs investigating.

Not always an overload, but with rcd's now days they sense leaks in electrical systems, imagine if you will a large water tank with a tiny pin hole in it, so that it still works as a tank, but just looses some water, the same thing applies to an electrical system and/or electrical appliances they can leak small amounts of power to ground. So possibly your system could have a small leak somewhere ?

I would very much doubt it has anything to do with what your electrician has tested and by coincidence you have an appliance which has developed a small fault which your rcd is detecting.

Does your CU (fuse board) have 2 RCDs?

What box is in the bathroom ?? Fuse board ?

Don't agree 100% with this. If it was a thorough inspection that included removing accessories, it could be the inspector pushed an accessory back into place and caused minor damage to say a neutral conductor that will randomly cause an N-E fault and consequently trip the RCD.

Hi - as above, the RCD is checking no current is leaking to earth. It's an additional safety protection for us, because it's that current leakage that can be the cause of electric shock.
