Just to add a bit of fire to the debate. I have in-front of me a sample 2391 paper with the following question-
An insulation resistance test between P N conductors on three individual single-phase circuits revealed the following values
0.00MOhm; 0.08MOhm; >200MOhm
What circuit conditions are indicated by these values? (3 marks)
How would you answer to obtain the full 3 marks?
