![]() "Ignoramus30685" wrote in message ... As I will sometimes test used 460v equipment, using my 240 - 476v, 45 kVA transformer, I would like to somewhat enhance my safety, in regards to "arc flash" and other such problems. What I want to do is this: 1) Wear heavy cotton clothing, like a work jacket 2) Wear a welding helmet 3) Stand on a piece of wood 4) Operate stuff with one hand only 5) As I turn something on, have my employee stand by and hold a handle of a disconnect leading TO the transformer. 6) If he sees or hears anything untoward, he would be instructed to immediately turn the disconnect off. Does this make sense? i You need better research than can be done on a newsgroup. Try finding NFPA docs on arc flash and how to protect from them. Email me (I don't get here often anymore) if you want a DOE document on electrical safety that has some good background info in it and is easy to understand. You might also visit Mike Holt's site - http://www.mikeholt.com/. It's for professional electrical engineers and electricians so tread carefully in the forums. |
