any domestic electricians in the house?
« on: November 05, 2008, 01:04:01 PM »
We've been in the house since mid July without any electrical incidents but in the last few days one of the trip switches in the box on the wall trips out and turns off all the sockets in the house. The lights are unaffected and the cooker which goes through its own switch is OK too. Because it was tripping so often, I was worried that the fridge/freezer would ruin the food in it and I've run an extension across from the garage to supply that.
I've turned off every socket in the house to see if it would still trip with no obvious draw on it. It still trips.
It might go off once every few hours or it might trip 4-5 times in one hour. When I reset the switch it often takes a few tries to get it to stay on.

Does anyone have any ideas or is it time to call in an electrician?

Originally i would have said that it could be a screw or nail gone into one of the wires for the sockets but it could be just a faulty trip switch!

if it is the trip switch is it an electrician job?
High Voltage stuff is kind of daunting to me. :o

Is it the 20A breaker or the ELCB (the bigger one) that trips.

I presume it is an earth fault in one of the wires/ sockets.

as gary c said, this is exactly what happened to me. It is either a socket wired wrong or a wire shorted to earth/neutral.

It is a trial and error job disconnecting checking and reconnecting. or else call in the Electrician who did the job in the first place. he f'd up, or the builder put a nail thru a wire.

then it is definitely an earth fault.

so go round each socket, pull it off the wall and check the connections?

I presume my tripping that big fella to the off position it'll be safe to go poking at sockets?

that'll be a job for tonight so. Saturday I was flushing radiators ::)

I'd rather be in the garage ;)

Used to be an electrician, not did much domestic, more commercial
has it been tripping since you did the radiators ?
got any small leaks soaking down the walls ?
I once worked at a house where the walls were so damp you could get a shock off the plaster  :o

I'd go and recheck all the rad connections

only an idea

sockets are relatively easy.... worth checking. On the wires,  I am not sure how you'd figured out which one is faulty - perhaps a multimeter checking the on the earth to live / neutral  ( with the power off) would identify which socket would get it.

Not sure though.

no, it was happening since before the radiators (I think)

even with all the sockets switched off it trips periodically.

I have a multimeter, I'll check the sockets with the trip switch off when I get home later on.

I'll let ye know how it works out...
