Much safer is just to call the power company, tell them you are doing maintenance on your panel and the seal was broken. Cut the seal and pull the meter. They will come out and replace the seal. Electricians and inspectors do this all the time.

street juice? You think it's lower once it's inside the panel or something? You actually advise people to work a panel where it has two hots (that are live) coming into it without experience, reliable knowledge of electricity? It's MUCH safer to call power company and have them pull the meter for you. That turns those incoming LIVE lines going into your main breaker, OFF for you. So that you don't accidently do something stupid and contact one (or both), or cause one (or both) to short out to neutral and/or ground. That would be bad for you, and, the transformer won't appreciate you either.
