Hi guys

Did an EICR last week in a council house and the occupant has complained to the council that during my testing I've damaged her TV! I did an insulation resistance test with line and neutral linked together, to earth. I normally do it at 250V then, if the reading is healthy, at 500V which I did in this case and recorded 140MegOhms. Also i usually switch off the sockets without unplugging the accessories but I can't actually remember switching the TV socket off on this occasion so it may have been in the on position. So is it possible to damage a TV at 500V with L+N together? I didn't test line to neutral seperately.

I went back and just checked the plug top and cordset and they are fine so maybe its an internal fuse that has operated. It's an LG LED TV and it's completely dead. Penny for your thoughts?

Thanks in advance

J.O.B.

Can you remember if it was the same TV that was there last week?

Need to make sure these sods have not swapped it for another.

Its a bit strange as linking L and N is supposed to stop that from happening. I am glad I am paranoid and always unplug everything.

seen this before years ago company replaced a load of plasma tv,s before I stopped it, same tv being passed around different houses.Boss just gave them a new tv and didn,t take old one which got passed on to next person.Stopped when I took the broken tv away.
 
After one decent homes rewire, Jabba The Hutt who inhabited the hovel (sorry I meant house, my fingers slipped) got in touch with tenant liaison and told them the night after we had finished there was a surge which damaged beyond repair her brand new (yeah right) fridge freezer (lots of other appliances were plugged in at the time but only this was damaged...hmmmm)
Furthermore she mentioned me by name and claimed that I had been round that morning and acknowledged that it had happened AND that it was my fault. After tenant liaison helped me recover from my laughing fit they rejected the claim only to receive a letter from a solicitor which stated something along the lines of "The new electricity I had installed was faulty"
Yeah the new electricity isn't a patch on the old stuff!
Chancers mate, the world is riddled with them. Tell them to prove it.

IT equipment does have an earth rail which can still damage componants, hence why pc's must be disconnected from circuits being IR'd.
I know most tv's used to be double insulated class2 but more and more do now seem to have an earth so iv'e noticed, so could be the case here. Bit of luck it is just a fast blow fuse on it but i would not want to play with it if in your shoes.
If it has damaged it were only talking a tv so not the end of the world, if it was me just pay a £60 tv man callout and if it has gone pop stick it on the insurance or pay a new one, sounds like a coucil contract you have so not worth losing it over a tv, accidents happen so don't let it eat you up.
 
Funny how it always happens in Rented houses, I had it once on a test where I heard this noise and the bloke came in and said his computers just 'blown up' and must of been something you were doing. I said thats funny mate as I was just filling out paperwork! He then got really angry with me and I said 'numbers on the back of the van mate'

Disagree strongly, if he accepts liability on this one word will spread like wildfire and if he goes back to that estate for any more testing there will be an avalanche of claims from the less than scrupulous. His premiums will rise exponentially
Stand your ground on this one mate

End of the day there's no way you blew the TV up because you ALWAYS unplug every appliance before doing any testing because otherwise you could get a wrong test result....

That's what you ALWAYS do without question....

I'm right aint i?




Just *nod* yes and stick with it....you know it's the right thing to do *nods slowly*

If you're IR testing with L+N to Earth @500V the only way that might cause a problem would be if there was an N-E reversal somewhere on a circuit.

However he has proven that there wasn't by following the full and correct method for testing an RFC

Quite right. Linking Line and Neutral keeps everything at same potential but seeing as "it was unplugged" there was no chance of it blowing. We had council rewire and the tenant wanted us to move a socket - next it came the redecoration because of the mess and holes left - we made the mistake of offering a small fee, not for the damage but for the delay in repositioning the socket. Two weeks later it was her neighbour wanted a socket repositioned after the rewire. We refused because she marked the positions. Next she said she wanted new carpets due to the mess. We refused as we didn't use paint or nail varnish!! SEVEN months later a solicitors letter saying we hit a gas pipe and she was overcome with fumes for seven months.

Our insurance company investigated and discovered the gas fitter who gave her the report was her brother. TV always show cowboy builders but don't mention tenants from hell
