Discuss Large Volt Drop in ring circuit in the UK Electrical Forum area at ElectriciansForums.net

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 )

It can't be that bad if it highlighted the problem, I just need more time to retest the whole system starting at the connections in the CU:)

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?
 
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. 
