Can someone give me some advice please?

I sat my C&G 2394 exam this week. Passed the practical, failed the multichoice by 1 question. Written paper next week. My question relates to one in the multichoice paper.

What is the correct sequence for safe isolation on a 3-phase motor? Can't remember the answers but none had the neutral - earth test.

Would appreciate some help on this one.
