Hi Folks
This is my first post, but I've been reading many posts over the last few months and have found this forum very informative and some times very humorous, Thank you all.

I have recently come across a problem whilst doing some PAT testing for a customer that has left me confused. Although this is nothing to do with PAT testing it was my PAT testing meter that highlighted the problem when I plugged it into a socket.

The property is a 4 year old Timber barn and the loft has a small ring circuit with a spur off it feeding a socket below for a small telly.

My problem is that all of the sockets are only giving voltage readings of 60v but the reading for the circuit at the CU is the standard 240v
The only thing that I can think of is that when building the property someone has banged a nail through a cable somewhere.
I have been round all of the sockets and checked connections etc and found nothing obviously wrong.
When I mentioned it to the customer he said don't worry its probably been like it for ever and the sockets only supply low voltage stuff anyway.

Well I am concerned that its wrong and there is possibly a nightmare waiting to happen.
Im thinking of contacting the customer and trying to get him to let me rectify the problem
Is there anything else it could be?

I await your reply's with baited breath :)
 
It can't be that bad if it highlighted the problem,
Not all bad , I'm angry with myself for believing in it ,and falling in the same trap again.
( Its inteligence - fogs the process at times )
Probably where the Nice round numbers come from !
( Now embarrassed at how wrong I was )

wjat fault are you expecting to find in the CU connections? Or is it a random guess?

Did you measure the 60V open circuit or with any load connected?
Did you carry out an earth fault loop impedance test of the circuit?
Did you observe any appliances working correctly whilst plugged in to an affected socket or do you only have the customers word for it?
 
Mr Random 2 , I thought my phone was bad ,
(Maybe he uses one of those voice recognition apps . )
No sugar coatings ,
Both feet first ,

so maybe I am --on another planet for sure--
Enjoying life , definitely !
Ah I am with you now.
 
Is that when my Spark symbol shows 230+/- 5% (on his Fluke)
Or just anything over " safe" 50V ?
(warning energised)
test voltage 50vIndicates the preset fault voltage limit. The default setting is 50 V. Some locations require the fault voltage be set to 25 V, as specified by local electrical codes. Press  when you turn on the tester to toggle the fault voltage between 25 V and 50 V. The value you set will appear on the display and will be saved when you turn the tester off. 

They ought to be able to check for the voltage going completely off using one MCB off at a time to confirm that. That would be my assumption...

Seen this where T&E has been fixed with a flat bend of too tight a radius.
