No offense taken... Note first words... "It means DONT GO NEAR IT!" Remembering HVAC guy, just joining ECN a week or two ago, and seeing red flags of 2700V from a guy who just got into a program, obviously near gear out of his league unattended. The wording was on the fly, (late at night from my usual bad back throbing alarm clock) and kinda roughly meant to deter attempts at exposure to voltages that 'act' much differently than the generic 120/240 that some are used to. At about the 277+ mark it has a tendancey to 'reach out and bite you' with little or no contact at all - depending on potential. So in retro-spect, there should be an 'especially' before that 'deadly". [Linked Image]

HVAC Tech I hope these guys that have you putting your hands on stuff went through the Whens, Hows and Nots (safety) of the gear you were in. At that voltage, one mistake could be your last. Off, AND grounded as well as with proper PPE should be the only way to approch that gear.

Steve, there ought to be a whole thread called "Nailed by Neutral" [Linked Image] I could go on, and on and on....
