This group of wires is on the side of the house (no cover on the patch box).
I tried tracing some of them (the orange arrow) and that seems to terminate at a phone connector box.
The three wires that you see (green arrow) goes to the pole in the back alley.
I know that's not the main electrical service because I can see the line that goes to the weatherhead (no pictures showing this)
I'm trying to clean up unused wiring that running around the house.
How do test and figure out the wires? I guess as a precaution I should also test to make sure that there isn't high voltage.
** Update ** I finally cleaned up the cables. It turns out that many have already been disconnected/cut from old connections in the house. I was able to pull the cables that were under the crawlspace and they all terminated at the box. I also. called the phone company and they removed them from my property.
