Hello,
I am trying to find out how to accurately identify both the size and type of an existing in ground service that runs from an outdoor mounted main panel to another building about 800 feet away. There is no identifying marks on the cable at either end and going by the physical dimensions it is closest to 300 mil stranded aluminum with a THHN insulation of which I know it is not !
The insulation is somewhat like a rubberized 14-3 cord ? I don't know what the standard cable types were when this was installed in the 70's so I could use a little help from the more experienced electricians out there,please.
I'm trying to avoid having to run new underground wiring.
Thanks,
Carl
