Can you describe again exactly where you are measuring these voltages ?

100V across immersion - no hot water
- Thread starter PHILatHOME
- Start date
Immersion cable connects to an isolating switch in the airing cupboard, the feed for this is chased down a wall to 'somewhere'.
I turn the switch off (open) and measure 100V across the L & N, at the same time I measure 230V between L and E and 150 between N & E.
My thoughts, if this circuit was all correct would be that I should read 230V across L and N with an open circuit and should read 0V between N & E. I don't understand why I am getting either of these readings L/N or N/E as they don't make sense unless maybe there is an earth fault (but just dont know!!!).

So neutral is broken or badly connected somewhere.
So you are measuring on the load side of the double pole switch, yes ?
