Has anyone else seen a 120 volt electrical service to a house?

I got called in one day to wire a simple ms09 Mitsubishi split system by an AC contractor I have done hundreds for over the years. His boys had the system installed already and were packing up when I got there. They never called me in advance to look the job over, they trust me to give them a fair deal every time. The whole street of shacks only had 120 volt single phase . Oops........
 
I have changed out a few over the years. If memory serves me right it required a 120 volt meter adapter to power the other half of the new panel while waiting for the POCO to change the drop and the old meter.
 
In rural areas of Texas I have seen overhead services that appeared to only have a single conductor. Are they 120V and using the earth as a return path?

As far as I know, you can't use single wire earth return systems at low voltages. They are typically medium voltage systems and are very rare in the US.
 
Only worked on one, POCO engineer got me the job but I can't remember if POCO or HO paid. I think POCO was phasing out all 120v meters, I built new service so they could use modern meter
 
There is actually a house right around the corner from me with one. They have a 120 volt, 30 amp service with 3/4 RMC going up the side of the house, no outside meter of course. The poco updated to triplex long ago and one wire is just taped off. Not surprisingly, they don't have an a/c units in the windows. :happyno:
