I have been hit with 277, and after that I bought some cheap combination
locks from Wal-Mart. I now cut off breaker, and lock box, or handle.
That hirt, and I learned from it. It will not happen again.
I have been an electrician since 85 and luckily have never been blasted by anything other than 120 and evenn than only maybe a hand to ground, never across my chest.But I learned in the electrical trade to always know where my non working hand is when I am in a panel.
Curious, I work occasionally with a sparky that I watched installing a bolt-in breaker one day. He had one hand on the handle of the nut-driver and the other hand on the shaft bolting onto a live bussbar. Why no zap? I don't get it cuz I've been on glass ladder and been smacked.

Answer is that electricity has to 'complete a circuit' to somewhere to 'bite you'. But I will say this clearly: DO NOT use this as an excuse to take chances. Because you never know when you ARE completing a circuit and do not realize it.

I'm glad your o.k but, I am suprised that you would leave the site, return to work on 460 without checking voltage again.
And if there was no disconnect at unit (code in canada), I would make dam sure no one could get to the panel while I was working.

I've been shocked by more power that was "off" then "on", trust nobody and always verify for yourself, and be careful trusting the little voltage testers with the light, tattle tells or whatever, some dont read when small backfeeds of lower then 40 volts is present.
Has Any One Been Shocked By 460
By All Means Get And Carry Lock Out Tags And Locks. I Carry Them And Lock Out When I Cant See The Disconect, Even On Residential.
Safety Takes More Time But Its Better Than Going Home Injured.
I'm religious when it comes to lock out/tag out. However, carelessness can get the best of ya.
About eight years ago, I was working on an old Mammoth packaged RTU. I was checking the system pressures. To do so, I had to crawl into the unit to get at the service valves. The compressor was running and the space was tight. My refer wrench slipped out of my hand and I went to retrieve it. Contorting my arm, I reached over the compressor. While doing so, I felt something move. It was the compressor terminal cover! Shortly after I was hit through my arm with 208. Fortunately, it blew me back against the condenser coil. Man, that arm of mine stung for three days. I had some redness but no burns and I was alive.
Lesson learned: Never stick any part of your body where you can not see it. Know your surroundings at all times. Do your job and return home safely at the end of the day.

in Canada we have 575-600v just for fun - 1 leg is 347 v to ground
Its killed more electricans and others than all other voltages combined
very common in building lighting and thats where it gets you
you ain't been lit up till you get hit by 347 man its a killer I'm sure 277 is almost as bad and I wouldn't want to test them both to see if ones harder than the other

That electrician never got zapped because the handle was insulated but what a stupid SOB, I would never touch a live busbar, what if someone touched you inadvertantly and he was grounded, you both would get it.
