My first was same as "CTwireman"

Had a couple due to my own how shall we say oversights but the most memorable

Instaling an extention telephone bell (yes that is correct a telephone bell)outside a building so I decided to connect up from the telephone socket first then conect up the external bell. All went well untill someone rang the phone and 50v gives you hell of fright when you are 20 ft up a ladder. It may have not been the electricity that could have killed me or even the fall. But the sudden stop at the bottom of the ladder not keen on that..................

I freely admit I am a coward when it comes to working with electricity. I just dont like pain
