Oh is that what you call working live nowadays, yes of course I have fitted an mcb in a live db, working live to me is playing with live bits in busbars etc

Although technically it is working live, fitting an MCB wouldn't bother me.

I have in the past drilled and tapped live bus bars. That is what I would consider live working. We followed a strict procedure, and had proper tools and equipment.
 
FYI, fitting an MCB into a DB is classed as working live, an electrician friend of mine got seriously hurt doing just this, all down to a faulty breaker which blew up in his face as he fitted it.
The HSE got involved and said there was no reason why the board should not have been switched off to carry out the work. His company got fined and he has the scars on his face and hands.
As with all accidents, its the unexpected that gets you..

I have done just that too, not today, it is just not worth it. HS would have a field day.
 
Oh memories
Going back a bit here but I remember one wonderful occasion fitting a 3 phase MCB in a KQ board and the damn thing just wouldn't click in so in that time honored tradition I decided to give it a little shove.
Yep it went then, straight in too far and shorted out on the metal panel behind.
Woke me up I can tell you.

How fat are your fingers @polo1? There's 2" between like and the other! It's certainly fiddly on an I phone, sometimes it takes 5 goes to get it right!
Is that how you spell 'goes'? You judge but careful to not press the dumb button! sausage fingers!
