Hi
If I disconnect earthing conductor and put a voltmeter between the earthing conductor and the earth rod how many volts should I expect?
None I would have thought.
However I get 60V with nothing plugged in and 110V with computer plugged in.
Caravan on tt system fed from tncs property - ( no earth exported )
Only 1 radial circuit with 4 sockets.
ze = 20 ohms
insulation resistance l - e, l - l = 999 M ohms +
lead supplying caravan insulation resistance as above
proven polarity
proven continuity of all conductors
Am I being dull ?
thanks
