Hello from Spain!
I am after some help and advice.
Whilst checking my supply ( which is TT and the whole installation is protected by a 30ma RCD) I have found the following
With the earth connected to the rod
L to N 240v
L to E 345v
N to E 148v
If I disconnect the earth rod, at the consumer unit I get
L to N 235
L to E 214v
N to E 7v
I rigged up a testing bulb and the voltage is real and not a phantom from my meter. The bulb lights up. Brighter on the higher volts. If I try this after the RCD it trips ( phew! ) which I'm guessing means the system is normally balanced.
When I checked at the incoming supply point, with my Consumer unit isolated, I earthed to the metal leg that holds my supply box I get the same voltages of 345v and 148v.
We live in a very remote rural location.
Is it possible to have both the N and L energised?
Thank you
Dave
