That would solve the issue that I raised at the beginning of the thread, but unfortunately I can't see that as a realistic method for everyday use.Normally use the incomming tails on the meter side as the "known" source.

Even with 2 trips I would have got the same result.My safe isolation procedure includes proving you have identified the correct circuit, motor, pump or what ever is to be worked on. This can be difficult some times but in this instance a couple trips between the MCB and the light circuit using the approved voltage tester should of been sufficient (this can be made much simpler if there are two of you).
I would have switched the MCB off. tested live on my proving unit, tested dead at the light, tested live on my proving unit. Then I would have done this again.
Also (as above), 2 trips would not really be realistic on a day by day basis.
I'm really not sure what the answer is. Luckily it is an extremely unlikely event. Statistically it will probably only happen perhaps once in a career lifetime so I am now fine
