The power company serving Honolulu stopped allowing electrical contractors cut service drop conductors and re-tap using split bolts or crimp connectors during service change outs about 10 years ago. Since then I have seen more than a few instances where the existing energized socket is pried off the wall while still energized, and suspended from the roof overhang by ropes, romex, once I witnessed a carpenters tool bag suspenders doing this duty, in order to allow a new service can to be placed in the same location as the existing can was. These "suspenders" hang like this for up to a week while waiting for the city inspector to check and clear the new socket install, and then the poco comes and re connects the new socket. This is supposed to be SAFER than allowing non company personel to touch the energized lines (cutting the existing service drop conductors, changing existing service and reconnecting the service drops. like we used to be able to do.)
