That's an impressive looking arc. I wonder how many volts were on
that cable?


I think the standard voltages for distribution is now 69,000v and
115,000v in most places.

Some lower ones are 13,500 volts but would not draw an arc like that.
The house we had in Duxbury was fed underground from the road to a
transformer closer to the house. It was 13,500v in a coaxial cable to
the primary of the transformer. The secondary fed two, 200 amp panels in
the house and another 100 amp panel in the garage. It shorted one day
where it ran into the ground by the road and the whole ground shook.
It's amazing though. The primary fuse on the pole is only a 15 amp fuse.

Lotsa volts anyway.

It would not open for me.

Around here, street distribution "medium voltage" is 13.5kv wye.
"Transmission" is 230kv delta.
