Large Volt Drop in ring circuit

[Andy]

Do a plan of the wiring - make sure you know where every cable goes.
Zs tests
R1/R2 tests

The results of the above will point you in the right direction.

will do
thanks

I would say this is a simple fault if appliances are operating, I am going for earth continuity.

How many threads I have read where voltage readings(regrettably sometimes with the wrong instrument)have been noted on an installation and all sorts of sometimes wild claims are made by the operator
Concentrating the mind on voltage readings and assessing the safety of an installation on those readings is a sure fire way of coming to wrong conclusions

There are better and tried and tested means of making the assessment of the safety of an installation
Those who are unsure of how or what to test,they are the usual culprits for not being aware that wrong assumptions can be made
I suggest refraining from condemning work based solely on voltage readings,that is until the proper safety tests confirm there actually is a problem

Already have ,(origin of operating volts limits)
No worries , this piece of string has too many unknowns !

take end to end readings at the db for that circuit. That will atleast highlight if the ring is open somewhere...
