Overhead resi and comm up to 400 amp, 3 phase, we cut at the drop, do what is necessary, and then re-connect.
All of the above is done after a permit is obtained, and the utility is notified.
Meter can seals we cut, after advising the utility.
Upon approval of inspection by the town, a cut-in card is issued to the utility, and they re-seal and install their crimps on the drop.
Wait for the POCO; don't hold your breath around here. (Bless the deregulation)
