At my company you need to use gloves for the voltage you are using the hotstick on. So in this case if it were 34kv single phase it would be 19.9, which would require us to use Class 3 gloves. I'm sure there will be a lot of different requirements for other companies, but that is what ours is. The class 2 glove I believe is rated for 17.5 with the newer OSHA rules. So if I get caught using a class 2 glove on a 34kv single phase PM, I will get time off.
