Was already in a grumbly mood about having to work outside today. It is freaking raining hard as hell down here, and electrictity and water go great together. Still though it could be worse I think to myself. I'm used to working in the rain and other less than ideal conditions. It goes with the trade. Anyway, the main part of the job I need to get done is fixing some lighting in the marquee over the front of the restraunt. No biggie except I have to climb into from the access holes mounted on top. I catch a break in the rain and drop through a hole into the sign. Working by feel I get the three lamps popped in and hop out and power it back up. Nothing, Nada, Zilch. So I gotta go back into said marquee again. Opening the middle access, I start to climb back into the sign. Now this sign runs off its own 120Volt sub panel which is mounted to the sign. It has 4 ckts. for incandescent lamps, 2 ckts. for florescent lamps (which was what I was doing today), and 9 ckts running neon lamps. Yes its that big. Anyway, while climbing into said sign my pant leg rolled up on my right leg some. As I set that foot down and was climbing off the built in step ladder my calf made contact with the secondary from a neon transformer. (someone installed it and just set it on top of the enclosure instead of putting it back in like the were supposed to.) I took all 15kv from that wretched little box into my right calf and out my left arm. My friends it was pain beyond pain. Pain of which I have never experienced before and hope to never again. I honestly wanted to die. It lasted about four seconds, and that was enough for me for a life time. Oh and theres no damage to myself just two small red spots on my leg.
Now for a little info on neon lighting. Neon runs off of a transformer, as I have already stated. In order to make it illuminate it takes high voltage and thusly uses low amperage. By increasing voltage you lower amperage. The typical transformers in big signs push between 6kv and 15kv. But only use 30-60millie amps. Also with a transformer you have primary and secondary windings. In this case the primary feed is 120volts and the secondary output is 15000volts.
