The utilities here are wierd, that's the only word that comes to mind. I suppose if we dereg things wil change..dunno...
Anyways, most of us will do an arieal live. There are many service laterals that we will arrange so as to a minimal downtime swap over once the power boys pull up. And i won't touch those steel JB's they have for thier UG systems..too tight for live work..

My technique for a live arieal bug simply comes from years of watching the power boys. The only difference is the actual connection, the use crimp-on's covered by an 'H-tap' which is only a snap on cover. They'll cut off anything i do, so i will usually use those 2-hole in-line connectors as they are cheap $$$.

If you really think here, the power boys could shut down the serving X-former, but usually don't.
