/diy/ - Do It Yourself

I have a 100A Pushmatic breaker box from the 50's and the 100A main breaker (pic related) trips after about 15 minutes when I have a bunch of stuff on that's drawing a total of about 60 amps. I think this means I need to replace the main breaker. I can get a new one for 100 bucks and I have already had to replace some branch breakers but my question is, how do you replace a main breaker without turning the power off at the meter / pole which I'm guessing would involve paying the electric company to come pull the meter / flip a switch at the pole? I was thinking to buy an insulated screwdriver and making some 1' long wooden chopstick / tweezer things to manipulate the main wires and hold them apart during the job. Am I on the right track? Thanks.
