This particular thing has been known to kill the odd Electrician working at a switch-board.
If a Neutral loses its reference to it's usual busbar, it then becomes a Phase conductor.
This is of course assuming that the circuit is still energised and the switch is on.
Leaning you arm up against the metal side of a switch-board body and holding a wire you thought was a Neutral before can be the easy way to get a fatal hand-to-hand shock.
Be careful around them Neutrals!.
