Once you are stuck on the wires you can't let them out. It's a feeling I do not recommend to anyone to feel it on their own skin. I worked on an 6KV substation with automation powered from 110V DC. One of the battery pole was in short circuit with ground. The automation was mounted in an iron electrical cabinet connected to the earth. It was very hot and I was sweaty. With the elbow supported by the cabinet floor, I've touch the other 110V pole on a relay socket. The muscles were blocked. The pain you feel cannot be narrated by words. You have to feel it and to scream to believe. :) Vasile --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
