I am a new Electrician. I have helped do dozens of panels but have always chose to do the inside work(panel work). I have helped do the outside as well but have never actually made the service connections at the weatherhead. I never had the opportunity to watch either. I cannot understand how the other person I was working with was not getting shocked as he was not wearing "hot gloves". He was a kind of shady character and told me as long as you're only touching one conductor at a time you cannot get shocked? As I stated earlier I do have hot gloves but have never used them nor performed this connection "LIVE"before. I'm also unaware of the different kind of connectors available. If anyone out there can give a new guy some help I'd appreciate it. Thank you.
