Don't confuse apples with oranges.But they actually can connect a live service drop, plug in a meter while live, etc. yet we hear all the preaching about how to work on anything live needs justification and there is not many conditions that justify it - it can always be turned off.
For the most part the equipment utilities deal with is intended to be worked on live, while the equipment we deal with is not, even though it has been common practice to do so.
There are lots of overhead services connected while hot, but I am not aware of any utility making live direct burial terminations.
