I Was Working On A High Energy Strobe System On The Bench, Late At Night 26 Years Ago Using A 500v Regulated Supply, I Was Tired, And Had The Supply Set To Max Current, And Voltage. Being Tired, I Had The Single Meter Set To Current (Thought 0 Volts), Clipped The Ground Lead To The PCB, And Held Onto The Ground Lead To Steady The PCB, And Grabbed The Positive Lead. At Full Voltage, And 500 Mils For A Minute (A Lead In Each Hand), After Getting My Thoughts To What Was Happening (Very Difficult Under The Present Circumstances)Stood Up And Walked Backwards, And Pulled The Leads Out. The Doctor Said I Should Have Been Dead On The Spot. I Guess The Great Spirit Was On My Side That Night. I Hope No One Here Has To Learn The Hard Way As I Did, Not Only Should Safety Be A Concern, But Mental Awareness, And Another Person In The Vicinity (In Case). Also. As You Get Tired, Dangerous Mistakes Are Made. I Still Have The Scars On Both Hands 26 Years Later As A Reminder Of My Stupidity.

War stories aside for a moment, I think the essence of the question is "afraid". It's my non-humble opinion that his fear is born of inexperience at that level, perhaps also a lack of proper training, and is therefore a 'good thing'. In such situations it's quite common for someone to make a mistake due to the distraction caused by their fear. I would submit that if your friend has no means (or need) to acquire the training, then the experience, which would change the fear to a rational respect - then he has no business messing about where he shouldn't and needs to have it done for him. He's not silly, he's not a coward; he's being quite sensible. Certain situations don't allow for mistakes - not even one. I also have practiced 'one hand only' around high voltage, for something like .......... years. (Hmmm. Where in the world did those number keys go?) Always careful, and I still have the marks to show the effects of an unexpected breakdown, or of waiting six months for an RF burn to heal, or simply of a lapse in concentration. Yes, Craig, we're old. ;<)) Fred -- <>< -- Outgoing checked by Norton AV Yahoo! Groups Sponsor ADVERTISEMENT ------------------------------------------------------------------------------ Yahoo!
