I have a friend with a small storage building behind their house.
She told me that the circuit breaker tripped to the building. I went and looked at it all. what a fustercluck.
The exposed cable insulation oxidized and has been shorting out, arcing and sparking along the length of the run. They fed the disconnect box with a 2 amp circuit breaker, but installed 60amp fuses in the disconnect. They only ran the Hot leg through the fuse, and they tied the neutral to the ground. Sheeesh.
They ran no conduit. The cable is stapled to the wall until it reaches the weatherhead. From the weather head to the second weatherhead, it is just hanging free-air and unsupported for about 10ft. By looking at it I would say it was not rated for aerial use, exposed to UV and unsupported.
I have never used aerial cable. What is it that I should ask for at the supply house? I usually ask for THHN for indoor stuff.
Even if it was rated for free air, why not run a support cable from an eye hook to another eye hook and hang the aerial of of that like normal?
It is only a 20am circuit for lights and receptacles in a 10 X 10 room.
