There are many of a certain age who have worked live, for shame!
Thing is now it is frowned upon, just like updated regs books we have to move with the tide.
One reason for it is the reduced competence of those being trained now, so they have to reduce the risks.
Training now is not what it was.
One comment on the hospital works.
When I work at my one of my local hospitals in their DB's I am not allowed to do my own isolation, nor even open the DB cover!
Their electrical engineer comes along, we test, we isolate, we test, he locks off, issues a ptw then we work.
Following this the process is reversed.
SO as far as working live in a board goes, in my local area no chance!
