This thing about being able to let go of 220 better than 110, or one I heard is 220 will knock you down but not hurt, or 220 will bounce off of you and 110 will stick....these are really all a bunch of wives tells I'v been hit by 110 plenty of times, at home working on some of my crazy projects, and even at work in the lab, working on a top swiched power supply. Every time I am able to let go. I have also herd of friends and fellow Engineers who got hit by 220 and they are not here any more.......take your pick I have never got hit by 220 this stuff is a killer, it is usully used to power big motors or furnance in cermercial applications.
