One way to die when working with electricity is for enough current to pass through your heart, not much is needed. Often you are protected by wearing shoes or by the current flowing through two parts of one arm. One of the most dangerous situations is when accidentally touching hot and neutral or a ground with opposing hands, so that current flows through your chest, potentially your heart, leading to the safety advice to "always keep one hand in your pocket."
Could you protect yourself by taking stranded wire and stripping several inches from each end and wrapping it around your wrists? The theory being the current would flow into the wire in one wrist, then through the wire (instead of your heart) to the other wrist and then back out your other hand. This would be similar to anti-static devices I've seen for working with computers.
But I wonder, would the electricity "find" the wire? I understand skin has some resistance, so it would have to pass through your skin to get into your hand in the first place, then pass through again to get into the wire then through your skin two more times in the other hand. How likely is that to be the path of least resistance?
If preventing electrocutions was this easy, I'm sure professional electricians would wear this as part of their standard gear. So why doesn't it work?
