Hi,
Just been to a block of flats - 1920's - testing the landlords lighting (that's all that there is communal area run off a timer, no switches for users).
There's no earthing to the lights - although they're all out of reach - but I got excellent Zs reading as I guess all the earthing is provided by the metal containment that goes around the property.
Firstly, if I'm doing a test cert should I say there are 'no earth' despite the fact I've got a reading to suggest otherwise (Zs) and...
Secondly, doing the insulation testing came up well as well, but then it should do i guess. Can I test between the earthed conduit and L & N to report IR or is that giving it more credence than it really has.
Thirdly, I don't think a landlords communal area is a 'special area' so presumably like household lighting earthing isn't essential if the fittings are double insulated (there are no light switches as it's all on a timer).
I've not come across this sort of problem before - is it common in properties of this age?
thanks in advance.
