Sorted a shorting fault at a pendant earlier this evening.
Whilst i was there they asked if I could look at the wall lights that have never worked since they moved in 2 years ago.
2 wall lights. Getting 244v line to earth, 0v neutral to cpc but 74v line to neutral.
The 74v line to neutral is my guess as to why any lamp will not work in the fittings.
I could really do too much investigating because it was late but it got me thinking.
What's usually the cause of this type a reading?
A Lost/loose/floating neutral?
