Got sent on this job the other day, 'Contactor burnt out' Oh dear.




IR and checked the windings of the motor all fine.

We replaced all the melted cabling, doing new whole runs of the the phases, also when we could on others and then cutting out the melted cable and crimping some of the longer control runs, replaced a few timers/relays, the contactor of course w/ overload. End to ended everything. IR on 100V. Done, we thought...

So then we powered the panel up in test and and the external suppy DP MCB for the the 110V Tx was tripping, I thought **** ive done something wrong, we then looked at the Tx, all the laminations were melted the varnish has all bubbled. So that was the fault.

Replaced the Tx and all worked

Worked in a factory awhile back their switchboard had blown up, Turns out days earlier they had had an older switchboard upgraded and the electricians doing the work didn't bother cleaning out the copper and steel filings in the bottom of the board, after turning the thing on the filings moved around causing the filings to act as a conductor between two of the phases and blew the thing up! No one was hurt thankfully but we got the insurance job to mop up

Re: Tell us about your faults !

This is a very common fault which often occurs in our houses- plug falls out of the receptacle. This fault due to the losing grip and worn contacts in receptacle. The solution for it is to replace the old receptacle with a new one.

The camera may well just be pointing at the door way.

In which case it's fine.

posted in the arms then rembered this thread.....

So sent to property, small bedsit, to carry out EICR after new tenant moved in. first thing she poins out is that the twin socket in the lounge must be kept on for the kitchen to work!!!
Ok I entertain the idea, nothings pluged in the normal twin socket, and as im starting to explain that the switch will only break whats ever pluged in she switches it off! and I watch the boiler and fridge die!!!!!!!!!!!!!

She switches the socket back on and the power to fridge and boiler comes back up.....


Im looking at it and I lean down and do the same. I have to admit I was gob smacked, a normal switched twin socket with nothing pluged in that kills the kitchen as soon as you switch it off.........


Ok it didnt take long to find the fault but if someone phoned up with such a fault you would bet your life they were lieing.


Turned out that there was no Ring continuity, and switching the socket on and off moved the brass conection at the back of the socket just enought to make and break the live conections.
Just shows the kind of random stuff that can cause a fault.

ohh the ring cont problem was a proper loose/ hanging out conection at the other side of the kitchen.....​

went to install some emergency lights in a small meeting hall today. There was a convenient pull chord near by double pole, so happily connected. All was going well until i came to screw it up and finish when the thing went bang. Thought the usual that somehow it s/c to earth or something, so tried again. Same thing. Since by this time I was running out of length on cable to do anymore connections I spent the day checking the circuit and connections and everything I could think of. The client came at the end of the day and saw me investigating and said the last electrician had to put cardboard between the connections and the earth terminal as they touch as you screw it up. SWAP THE THING IF FAULTY. Annoying to say the least. normally the first thing I check but since it worked perfectly when i attended i didn't think anything of it
