Bottom line is really,
If you intend to cut PoCo seals on meters, you are required to let that PoCo know before-hand and get permission.
All of us Lines Co inspectors over here (in my area anyway), use crimp tools unique to each Inspector, to crimp lead/wire seals.
On the other side of the coin, all electricians in this area have our cell numbers and ask if it is OK to cut any of our seals, I've never turned an electrician down yet.
