I remember like it was yesterday, back in 98' I was working at Ft Benning Ga. Installing new ballasts in 277v fixtures, I disconnected the hot..capped it off, then same with the Neutral, but before I capped it with a wire nut, I let my left finger slip down on to the copper..my other 'paw' was resting on the backside of the ballast cover. OUCH!
