Yes daughter in law was really worried and I went up to sort it out. Everything was RCD protected and my son had a full test set so sure the RCD was going to trip at 30 mA in 40 ms but whole house was being rewired and there was an array of extension leads.
Fault was a broken earth wire in an extension lead and correcting did not trip the RCD.
She was getting a shock when she touched the caravan to get in and out but I could not feel anything myself.
In hind sight I would say no real danger but I was not going to take the chance.
Sizewell 'B' was another reports of sparks coming from the tower crane hook this crane was at the time tallest in Europe. The whole structure was steel and power was 415 volt three phase to a auto transformer then 380 volt to crane. Reported sparks 1/2 inch long. We tested everything we could think of but no faults found but also we saw the sparks from the hook so no silly woman and panic attack there were clearly sparks from the hook but only when the crane was in line with the wind. We came to the conclusion it was static from the wind.
We read
about Emma Shaw and clearly there are times when there is a very real danger and every time we have to investigate.
We we told in college the story about an electrician and a central heating boiler where he put a lose green wire onto a earth spade and it seems it was the normally closed contact of the on/off switch so with the boiler on no problem only when switched off was there a line wire connected to earth. Not sure if real or made up by lecturer but it would seem he tested with everything switched on so found no fault. Court said had he not been called to home because of a shock it would have been considered and an accident but since before the death he had been called to check as mild shock had been received then considered as manslaughter. This was pre-internet so no way to verify the story.
But in essence what he was saying everyone can make a mistake but once any one highlights the possibility there is a fault then it becomes negligent not simply a mistake.
So if some one from "londoniese" family is now electrocuted when he has declared he thinks there is a problem he would likely face manslaughter charges for not doing something to rectify the problem. But if a family member was electrocuted without some warning signs then he would not face any charges.
I clearly hope nothing goes wrong and it turns out to be something like with my daughter in law but now he has posted on here he has no option but to get an electrician there is no other option.
Daft as it may seem proving AOK is harder than finding a fault.
