Thats as maybe, but I don't set the rules where I work for does. Besides it wasn't specifically lighting breakers they were messing with, but machinery breakers as well. This is dangerous as I have lockoffs etc to enable me to work safely isolated.
The machine was tripping and these people were re-setting the breaker, whilst people still had their heads and various bodily parts in the machine still I saw some nasty accidents caused by this, granted flicking a lightswitch breaker back on is different, but if several breakers are down and no labling is present in the board as is normally the case then how can you know which breaker does what, you could turn on a breaker that could cause a fatality. unskilled people do not normally know what all the different numbers on a breaker means, a 6amp is the same as a 32 to them!!
